• undertone-htb.js - This is your partner module file, by default it contains a template divided into multiple sections which need to be completed.
• undertone-htb-validator.js - This is the validator file for the configuration object that will be passed into your module.
• undertone-htb-exports.js - A file that contains all of the modules exports (i.e. any functions that need to be exposed to the outside world).
• spec - Contains the unit tests for the module.
  • mockPartnerConfig.json - this is a mock partner config for your module that will be used for unit testing.

Getting Started

1. Complete the undertone-htb.js file
   • undertone-htb.js is where all of your adapter code will live.
   • In order to complete the partner module correctly, please refer to the Partner Module Overview and the Utility Libraries sections.
   • Please refer to the Partner Requirements and Guidelines when creating your module. Ensure requirements are met to streamline the review process.
2. Complete the undertone-htb-validator.js file

   • Things like type and null checks will be done here.
3. Complete the undertone-htb-exports.js file
   • This file will contain any functions that need to be exported or exposed to the outside world. Things like render functions, custom callbacks, etc. Any legacy render functions will also need to be exposed here. Anything added to the shellInterface.UndertoneHtb will be accessible through window.headertag.UndertoneHtb
4. Run & Create Unit tests for your module
   • Inside the spec folder you will find a set of basic unit tests for your module.
   • You must pass these basic unit tests before submitting your module.
   • In addition, you should create more specific unit tests with actual values based on mock ad responses to confirm that your module is working as expected.
   • Please refer to the Testing section below for more information.
5. Submitting for Review
   • Once the module has been verified submit a pull request from the development-v2branch to the master-v2 branch for the Index Exchange team to review. If everything is approved, your adapter will be officially certified!

Standard HTW Creative Tag

Our standard creative tag in dfp looks as follows:

<script type="text/javascript">
var w = window;
for (var i = 0; i < 10; i++) {
    w = w.parent;
    if (w.headertag) {
        try {
            w.headertag.UndertoneHtb.render(document, %%PATTERN:TARGETINGMAP%%, '%%WIDTH%%', '%%HEIGHT%%');
            break;
        } catch (e) {
            continue;
        }
    }
}
</script>

Partner Requirements & Guildelines

In order for your module to be successfully certified, please refer to the following list of requirements and guidelines. Items under required must be satisfied in order to pass the certification process. Items under guidelines are recommended for an optimal setup and should be followed if possible.

General

Required

• The only targeting keys that can be set are predetermined by Index. The partner module should not be setting targeting on other keys.
• Must support the following browsers: IE 9+, Edge, Chrome, Safari, and Firefox

Recommended

• Please use our helper libraries when possible. Refer to our Utility Libraries documentation below. All of the utility functions in this library are designed to be backwards compatible with supported browsers to ease cross-browser compatibility.

Bid Request Endpoint

Required

• Must provide cache busting parameter. Cache busting is required to prevent network caches.
• Partner endpoint domain must be consistent. Load balancing should be performed by the endpoint.
• Your endpoint should support HTTPS request. When wrapper loads in secure pages, all requests need to be HTTPS. If you're unable to provide a secure endpoint, we will not be able to make requests to your ad servers.

Recommended

• Your module should support a single request architecture (SRA) which has a capability to send multiple bid requests in a single HTTP request.
• Partner should use AJAX method to make bid requests. Please use our Network utility library for making network requests, particularly the Network.ajax method. This ensures the requests will work with all browsers.

Bid Response

Required

• Returned bid must be a net bid.
• Pass on bid must be explicit in the response.
• All returned bids shall be in the currency trafficked by the publisher.
• Size must be returned in the response. The sizes must also match the requested size. This size parameter will be validated.
• Encrypted prices must be flagged in the response.

Pixels & Tracking Beacons

Required

• Pixels/beacons must only be dropped only when the partner wins the auction and their ad renders.
• Dropping pixels during auction slows down the execution of auctions and is not allowed by Index Exchange.

DFP Setup

Required

• DFP line items, creatives, and render functions will be set up by the Index Exchange team.
  
  

Partner Module Overview

Prelude: Configuration & Parcels

The Header Tag Wrapper passes each partner a configuration object that has been configured based on a publisher's website. This object contains all the configuration information required for the wrapper, including partner-specific slot mappings, timeouts, and any other partner-specific configuration. The partner-specific slot mappings dictate how ad slots on the page will map to partner-specific configuration. There are 2 concepts to be familiar with when understanding how slots on the page are mapped back to partner-specific configuration. Header Tag Slots, which refers to htSlots and partner-specific configuration, which refers to xSlots in the codebase.

• htSlots - This is an abstraction of the googletag.slot object.
  • These will need to be mapped to xSlots.
• xSlots - These are also an abstraction for partner-specific configuration that will be mapped to htSlots.
  • These represent a single partner-specific configuration.
  • An xSlot is how a partner can map their ad server specific identifiers (placementIDs, siteIDs, zoneIDs, etc) to the htSlot object.
  • It can represent a single or multiple sizes.
  • Multiple xSlots can be mapped to the same htSlot.

Example Partner Configuration Mapping

{
    "partners": {
        "UndertoneHtb": {
            "enabled": true,
            "configs": {
                "xSlots": {
                    "xSlot1": {
                        "placementID": "123",
                        "sizes": [ [300, 250], [300, 600] ]
                    },
                    "xSlot2": {
                        "placementID": "345",
                        "sizes": [ [300, 250] ]
                    }
                },
                "mapping": {
                    "htSlotID-1": [ "xSlot1" ],
                    "htSlotID-2": [ "xSlot2" ]
                }
            }
        }
    }
}

Based on the mapping defined in the partner config, Parcels will be generated for every xSlot/htSlot pair. Parcels are objects that carry different kinds of information throughout the wrapper. In the context of the adapter, parcels are the input into your adapter. Parcels carry information regarding which slots on the publisher's page need demand. More specifically parcels contain information like xSlot reference, htSlot references, demand (after its been applied by the adapter in parseResponse), etc. Each parcel represents a single combination of an htSlot and an xSlot.

Each parcel is an object in the following form:

{
    "partnerId": "UNDR",
    "htSlot": {
      "__type__": "HeaderTagSlot"
    },
    "ref": "googletag.Slot",      // reference to the slot on the page, in this example it is a googletag slot
    "xSlotRef": {   // contains the reference to the xSlot object from the partner configuration.
      "placementID": "123",
      "sizes": [ [300, 250], [300, 600] ]
    },
    "xSlotName": "1",
    "requestId": "_fwyvecpA" // generated by the wrapper is used to map the creative back to a piece of demand.
                            // This will show up as targeting under the id key, and is used by the render function.
}

These parcels will be fed into both of the functions that your adapter needs to implement:

1. First generateRequestObj will need to craft a bid request for the parcels that need demand.

2. Second parseResponse will take the same parcels and apply the demand (set specific properties in the parcel objects) that is returned from the bid requests to the same parcels and send them back to the wrapper.

High Level Event Model

1. The Header Tag Wrapper script tag is loaded on the page.
2. Wrapper specific configuration validation is performed.
3. All the partner modules are instantiated.
   • Partner-specific configuration validation is performed - checking that all the required fields are provided and that they are in the correct format.
4. An external request for demand is made to the wrapper. This can be via a googletag display or refresh call, or by other methods depending on the wrapper product in use. The wrapper requests demand from the partner modules for the required slots (provided in the form of parcels).
   • The wrapper calls generateRequestObj(returnParcels) for every partner module.
   • The adapter then crafts and returns a request object based on the parcels (containing slot information) specified.
   • The wrapper then sends out a bid request using the request object.
   • Depending on how the adapter is set up and whether jsonp is supported, a response callback (adResponseCallback) is called.
   • The adapter parses the response (parseResponse) and attaches the demand to the same returnParcels. It also registers the ad creative with the wrapper's render service.
   • The returnParcels are then sent back to the wrapper.
5. The wrapper applies targeting using the demand from the returnParcels.
6. If the partner wins the auction in the ad server, their creative code will be returned and executed.
   • The creative code contains a call to the wrapper's render function.
7. The partner ad is rendered.

Creating a Partner Module

In this section you will be filling out the undertone-htb.js, undertone-htb-exports.js, and the undertone-htb-validator.js files to create your module.

Step 0: Config Validation (undertone-htb-validator.js)

Before you get started on writing the actual code for your module, you need to figure out what your partner configuration (refer to Configuration) object will look like. This is crucial because it will determine the input (parcels) to your module's core functions.

Once you have a basic idea of what this will look like, and how you will uniquely identify each slot on your server (via xSlot placementId or other inventory codes) you will need to validate this configuration. This validation will be performed by the wrapper using the undertone-htb-validator.js file.

The undertone-htb-validator.js file contains a single export, a partnerValidator function, that takes in the configuration object that will be fed to your module's constructor (refer to Configuration for an example layout) and validates it via type checks. The type checks are performed using an external library called schema-inspector, for which the documentation can be found here https://github.com/Atinux/schema-inspector.

We have provided a very basic validation schema in undertone-htb-validator.js that is based off of the example mockPartnerConfig.js object found in the spec/support directory for testing (refer to the Testing section for the testing structure).

Once you have filled this file out, you can continue actually writing your module!

Step 1: Partner Configuration (undertone-htb.js)

This section involves setting up the general partner configuration such as name, default pricing strategy as well as the general format of incoming/outgoing bids for the adapter. Please read the following descriptions and update the __profile variable if necessary.

• partnerId - This is simply the name of our module, generally if your module is a bidder the name will end with Htb. The format of the name should be PartnerName{Type}.
• namespace - Should be the same as partnerId, it is the namespace that is used internally to store all of variables/functions related to your module, i.e. adResponseCallbacks.
• statsId - A unique identifier used for analytics that will be provided for you.
• version - If this is the first iteration of your module, please leave this field at 2.0.0.
• targetingType - The targeting type of your bidder, the default is slot for slot level targeting but could also be page.
• enabledAnalytics - The analytics that the wrapper will track for the module. requestTime is the only currently supported analytic, which records different times around when bid requests occur.
• features - Extra features that a partner can support
  • demandExpiry - Setting an expiry time on the demand that partner returns.
  • rateLimiting - Used for limiting the amount of requests to a given partner for a given slot on pages that support rate limiting in dfp.
• targetingKeys - Different targeting keys that will be used to record demand for a given parcel.
  • id - This key will be used to trace back the creative that has won in dfp for rendering.
  • om - This key signals the open market bid in cpm.
  • pm - This key signals the private market bid in cpm.
  • pmid - This key signals the private market deal id.
• bidUnitInCents - This tells the wrapper the unit of the bid price returned by your endpoint. The unit is in terms of cents, thus it should be set to 100 if your endpoint returns dollars, 1 if your endpoint returns cents, 0.1 if your endpoint returns tenth of a cent, etc. Note that this value must be an integer power of 10.

The last three properties are critical for the wrapper to understand how to interact with the endpoint:

• callbackType:
  • Partner.CallbackTypes.ID - Use this option if your endpoint accepts an arbitrary identifier in requests which will be returned in the matching response. You will need to set this callbackId in the generateRequestObj function and retrieve it in the adResponseCallback function. This is the preferred method for matching requests and responses. Pass the following reference into your request object when generating the request object in generateRequestObj. SpaceCamp.NAMESPACE + '.' + __profile.namespace + '.adResponseCallback'. You will need to fill out the adResponseCallback function to store the ad response in the __baseClass._adResponseStore[callbackId] object, where callbackId is the same callbackId that was passed back to the wrapper as part of the object that is returned in generateRequestObj. The wrapper will use the callbackId to reference to pull your stored ad response from that adResponseStore and feed it back to parseResponse. You will also need to expose this function inside your exports file, see below exports section for more information.
  • Partner.CallbackTypes.CALLBACK_NAME - Use this option if your endpoint has no parameter which can be used as a callback ID. The wrapper will generate a new callback function for each request, and use the function name to tie requests to responses. Similarly to the above ID method, you can reference the generated ad response callback as such: 'window.' + SpaceCamp.NAMESPACE + '.' + __profile.namespace + '.adResponseCallbacks.' + callbackId, where callbackId is the same unique callbackId that is passed back to the wrapper as part of the object that is returned in generateRequestObj. Unlike the ID method above, you do not need to fill out the adResponseCallback function. The response will simply be passed into the parseResponse function.
  • Partner.CallbackTypes.NONE - Use this option if your endpoint supports AJAX only and will return a pure JSON response rather than JSONP with a callback function. In this mode your endpoint will not receive any demand requests if the user is using a browser which does not fully support AJAX, such as Internet Explorer 9 or earlier. In this mode, you also do NOT need to provide a callback function in generateRequestObj.
• architecture:
  • Partner.Architectures.MRA - Use this option (Multi-Request Architecture) if your endpoint requires a separate network request for each ad slot. In this mode your endpoint will receive one network request for every xSlot mapping active in the current wrapper demand request.
  • Partner.Architectures.FSRA - Use this option (Fully Single-Request Architecture) if your endpoint can handle any number of slots in a single request in any combination, including multiple requests for the same slot. In this mode your endpoint will receive a single network request per wrapper demand request.
  • Partner.Architectures.SRA - Use this option (Single-Request Architecture) if your endpoint can handle any number of slots in a single request, but cannot repeat the same xSlot more than once in a given request. e.g., you use a placementId and can receive a request for multiple placementIds at once, but not for the same placementId twice. The wrapper will arrange the mapped xSlots into the minimum possible number of network requests to your endpoint.
• requestType:
  • Partner.RequestTypes.ANY - Use any request type when making requests. The wrapper will attempt to make an AJAX request for your bid requests, if XHR is not supported, the wrapper will attempt to make a JSONP request if possible.
  • Partner.RequestTypes.AJAX - Use only AJAX for bid requests. Note, if the browser does not support ajax the bid requests will not go out.
  • Partner.RequestTypes.JSONP - Use only JSONP for bid requests.

Step 2: Generate Request URL (undertone-htb.js)

This step is for crafting a bid request url given a specific set of parcels.

For this step, you must fill out the generateRequestObj(returnParcels) function. This function takes in an array of returnParcels. These are the parcel objects that contain the different slots for which demand needs to be requested.

The wrapper will ensure that the array contains an appropriate set of parcels to pass into a single network request for your endpoint based on the value set in __profile.architecture. Note, in the particular case your architecture is MRA, this array will have length 1.

Using this array of parcels, the adapter must craft a request object that will be used to send out the bid request for these slots. This object must contain the request URL, an object containing query parameters, and a callbackId.

The final returned object should looks something like this:

{
    url: 'http://bidserver.com/api/bids' // base request url for a GET request
    data: { // query string object that will be attached to the base url
        slots: [
            {
                placementId: 54321,
                sizes: [[300, 250]]
            },{
                placementId: 12345,
                sizes: [[300, 600]]
            },{
                placementId: 654321,
                sizes: [[728, 90]]
            }
        ],
        site: 'http://google.com'
    },
    callbackId: '_23sd2ij4i1' //unique id used for pairing requests and responses
}

If your endpoint uses POST please add the following networkParamOverrides object to your return object:

{
    url: 'http://bidserver.com/api/bids' // base request url for a POST request
    data: { // will be the payload in the POST request
        slots: [
            {
                placementId: 54321,
                sizes: [[300, 250]]
            },{
                placementId: 12345,
                sizes: [[300, 600]]
            },{
                placementId: 654321,
                sizes: [[728, 90]]
            }
        ],
        site: 'http://google.com'
    },
    callbackId: '_23sd2ij4i1' //unique id used for pairing requests and responses,

    /* Signals a POST request and the content type */
    networkParamOverrides: {
        method: 'POST',
        contentType: 'text/plain'
    }
}

More information can be found in the comment section of the function itself.

Step 3: Response Callback (undertone-htb.js)

Once the request from Step 2 finishes the adResponseCallback will be called to store the returned response in a adResponseStore object.

If __profile.callbackType is set to CALLBACK_NAME or NONE, the wrapper will handle the callback for you and you can remove this function. If it is set to ID, you must retrieve the callback ID from the network response and store that response in the _adResponseStore object keyed by the callback ID.

See the function in the template for details.

Step 4: Parsing and Storing Demand (undertone-htb.js)

In this step the adapter must parse the returned demand from the bid response and attach it the returnParcels objects. The returnParcels array will be one of the same arrays that was passed to generateRequestObj earlier.

This step involves first matching the returned bids to the internal returnParcels objects. This can be done via some identifier that was setup for an xSlot (for example, a placementId) in the partner configuration and the same id being present in the bid response object.

This function first iterates over all of the returned bids, parsing them and attaching the demand to the returnParcel objects (which will be implicitly passed back to the wrapper). This step also involves registering the creative (if returned) with the render service, which is responsible for storing and rendering that creative if the corresponding demand wins the DFP auction.

In order to complete this step correctly, please fill out the section which includes the matching criteria. This step is necessary to map returnParcel objects to the returned bids correctly. In order to do this, we need to use some common criteria that is present both in the xSlot configuration and in the returned bids (usually placementIds or inventory codes).

Also please fill out each of the variables for each bid, these will be attached to the parcel objects to store the demand:

• bidPrice - The bid price for the given slot
• bidWidth - The width of the given slot
• bidHeight - The height of the given slot
• bidCreative - The creative/adm for the given slot that will be rendered if is the winner. Needs to be decoded and ready for a doc.write.
• bidDealId - The dealId if applicable for this slot.
• bidIsPass - True/false value for if the module returned a pass for this slot.
• pixelUrl - If you require firing a tracking pixel after your creative wins and your tracking pixel is not part of the original adm that is rendered, please provide the decoded url of the tracking pixel here. This pixelUrl variable will then be passed to the __renderPixel function, which will then be called by either your module's specific render function or a generic rendering function depending on the line item setup.

After filling out these objects, the resulting returnParcel objects should look something like this:

{
    "partnerId": "UNDR",
    "htSlot": {
      "__type__": "HeaderTagSlot"
    },
    "ref": "googletag.Slot",      // reference to the slot on the page, in this example it is a googletag slot
    "xSlotRef": {   // contains the reference to the xSlot object from the partner configuration.
      "placementID": "123",
      "sizes": [ [300, 250], [300, 600] ]
    },
    "xSlotName": "1",
    "requestId": "_fwyvecpA",

    // notice these new fields with demand
    "targetingType": "slot"
    "targeting" : {
        "ix_undr_id": ["_230l09jd2"],
        "ix_undr_cpm": ["300x250_2.50"]
    },
    "price": 2.50,
    "size": [300,250],
    "adm": "<script> test creative </script>"
}

Step 5: Rendering Pixel (undertone-htb.js)

This step is only required if your adapter needs to fire a tracking pixel after your creative renders. The function __renderPixel will be called right after we render your winning creative. It will be called with the paramter pixelUrl that needs to be filled out in __parseResponse.

Step 6: Exports (undertone-htb-exports.js)

In this step, you will be required to fill out the exports file for your module. This file will contain all of the functions that will need to be exposed to outside page if they need to be accessed outside of the wrapper. In the usual case, all you will need to change in this file is your partner module's name in the included snippet:

shellInterface.UndertoneHtb = { //shell interface is the window variable that is accessable through the window object, currently this will always be window.headertag
    render: SpaceCamp.services.RenderService.renderDfpAd.bind(null, 'UndertoneHtb')
};

This snippet, exposes your module's render function to the outside world via the window.headertag namespace.

If your module requires using a custom adResponse callback via Partner.CallbackTypes.ID callback type, that callback will need to be exposed here. Which would look something like this:

if (__directInterface.Layers.PartnersLayer.Partners.UndertoneHtb) {
    shellInterface.UndertoneHtb = shellInterface.UndertoneHtb || {};
    shellInterface.UndertoneHtb.adResponseCallback = __directInterface.Layers.PartnersLayer.Partners.UndertoneHtb.adResponseCallback;
}

If your module requires using a custom adResponse callback via Partner.CallbackTypes.NAME callback type, that callback swill need to be exposed here. Which would look something like this:

if (__directInterface.Layers.PartnersLayer.Partners.UndertoneHtb) {
    shellInterface.UndertoneHtb = shellInterface.UndertoneHtb || {};
    shellInterface.UndertoneHtb.adResponseCallbacks = __directInterface.Layers.PartnersLayer.Partners.UndertoneHtb.adResponseCallbacks;
}

  • floor - Minimum acceptable bid price.
  • inputCentsMultiplier - Multiply input bids by this to get cents. This is identical to bidUnitInCents in __profile.
  • outputCentsDivisor - Divide output bids in cents by this.
  • outputPrecision - Decimal places in output.
  • roundingType - Should always be 1.
  • buckets - Buckets specifying rounding steps.

Note that bid transformer instances suitable for dfp targeting and price reporting are already provided via __baseClass._bidTransformers. It is recommanded to use the provided instances as they are sufficient for almost all use cases.

Testing

General Test Structure

For our unit testing suite we are using a combination of jasmine as a test runner, chai for assertion and schema-inspector for type validation.

The spec folder is where all of the testing files are contained and is structured as follows:

• spec - The main folder for all of unit testing
  • support - Contains various stubs and mock data
    • mockPartnerConfig.json - Contains your module mock partner config that is used throughout the suite
    • mockResponseData.json - Contains your module's mock response data that is used in the parseResponse.spec.js test cases.
    • libraryStubData.js - Stubs for various libraries
    • partnerStub.js - Stub for the partner library
    • jasmine.json - Jasmine test runner config
  • generateRequestObj.spec.js - The spec for testing generateRequestObj function
  • parseResponse.spec.js - The spec for testing parseResponse function
  • profile.spec.js - The spec for testing the partner's profile configuration

As you can see, we have divided the spec files based on the different functions/areas that you need to fill out for your module.

Running Basic Tests

In order to submit your module for review, you must first pass all of the basic test cases included in the repository. In order to run these tests you must first install all the necessary npm packages by running npm install and then simply run the command npm test from the root of the repository to execute the tests. NPM version 3. 8.6 and node version v6.1.0 were used when developing these tests.

Before running the npm test command you must first fill out both the mockPartnerConfig.json to contain a correct sample configuration for your partner. Based on this configuration, parcels will be generated. For SRA partners, all of the slots outlined in your mockPartnerConfig will have corresponding parcels generated. For MRA, each of the generated slots will be fed into your functions one at a time .

You will also need to fill out the mockResponseData.json file to match the mockPartnerConfig.json. This file will contain a json object with the following three properties that need to be filled out accordingly.

• bid - this is the response data array for in the case of real bids, this is used for the should correctly parse bids test cases. If your partner is MRA, keep this an array and put response objects inside it, one for every generated return parcel. If your partner is SRA, make this property a single object that contains the response.
• pass - same as bid but used to mock bid passes.
• deals - same as bid but used to mock deals. Should include some sort of dealid field.

Note: These ad response should match your mockPartnerConfig.json in the sense that there should be the correct number of objects/demand in this object for each one of the returnParcels that are generated from your partnerConfig.

For example, mockPartnerConfig.json contains a sample partner config. Here are the different returnParcels arrays that will be generated.

NOTE: This is an array of parcels, for SRA architectures the entire array is fed into your functions but for MRA architectures one parcel at a time is fed into your functions. This is because MRA partners have one request per slot.

var returnParcels = [{
    partnerId: 'UndertoneHtb',
    htSlot: { getId: function () {
        return "htSlot1"
    } },
    ref: '',
    xSlotRef: { placementId: '54321', sizes: [ [300,250] ] },
    requestId: '_1496788873668',
  },{
    partnerId: 'UndertoneHtb',
    htSlot: { getId: function () {
        return "htSlot1"
    } },
    ref: '',
    xSlotRef: { placementId: '12345', sizes: [ [300,600] ] },
    requestId: '_1496788873668',
  },{
    partnerId: 'UndertoneHtb',
    htSlot: { getId: function () {
        return "htSlot2"
    } },
    ref: '',
    xSlotRef: { placementId: '654321', sizes: [ [728,90] ] },
    requestId: '_1496788873668',
  }]

An example mockResponseData.json will be structured, according to the above returnParcel example, as follows depending on the architecture of your partner.

For SRA:

{
    bid: {  // Notice how this is an object containing the demand for ALL the parcels.
        54321: {
            price: 23,
            adm: '<script> test </script>'>,
            width: 300,
            height: 250
        },
        12345: {
            price: 10,
            adm: '<script> test2 </script>'>,
            width: 300,
            height: 600
        },
        654321: {
            price: 15,
            adm: '<script> test3 </script>'>,
            width: 728,
            height: 90
        }
    },
    pass: { // Contains only passes
        54321: {
            pass: true
        },
        12345: {
            pass: true
        },
        654321: {
            pass: true
        }
    },
    deals: { // Contains dealids
        54321: {
            price: 23,
            adm: '<script> test </script>'>,
            width: 300,
            height: 250,
            dealid: 'DEAL1'
        },
        12345: {
            price: 10,
            adm: '<script> test2 </script>'>,
            width: 300,
            height: 600,
            dealid: 'DEAL2'
        },
        654321: {
            price: 15,
            adm: '<script> test3 </script>'>,
            width: 728,
            height: 90,
            dealid: 'DEAL3'
        }
    }
}

For MRA:

{
    bids: [ // notice this now an array. again this is because in MRA there is one request per slot
            // and each object represents a single response
        {
            price: 23,
            adm: '<script> test </script>'>,
            width: 300,
            height: 250,
        },
        {
            price: 10,
            adm: '<script> test2 </script>'>,
            width: 300,
            height: 600
        },
        {
            price: 15,
            adm: '<script> test3 </script>'>,
            width: 728,
            height: 90
        }
    ],
    pass: [ // Contains only passes
        {
            pass: true
        },
        {
            pass: true
        },
        {
            pass: true
        }
    ],
    deals: [
        {
            price: 23,
            adm: '<script> test </script>'>,
            width: 300,
            height: 250,
            dealid: 'DEAL1'
        },
        {
            price: 10,
            adm: '<script> test2 </script>'>,
            width: 300,
            height: 600,
            dealid: 'DEAL2'
        },
        {
            price: 15,
            adm: '<script> test3 </script>'>,
            width: 728,
            height: 90,
            dealid: 'DEAL3'
        }
    ]
}

These tests perform basic type checks and make sure that all of the required fields have been filled out correctly. For example, if the mockData returned a bid, each of the parcels above for an SRA architecture bidder should contain new additional fields for price, size, creative, and targeting.

However these tests are very basic and we encourage you to write your own test cases to further confirm the functionality of your module. Please refer to the next section on how to write additional test cases.

Creating Additional Tests

In order to create additional test cases and further verify your module, please fill out the ADD MORE TEST CASES TO TEST AGAINST REAL VALUES section in both generateRequestObj.spec.js and parseResponse.spec.js for your corresponding module architecture type.
