| [[add-canvas-elements]] | ||
| === Add elements | ||
|
|
||
| Create a story about your data by adding elements to your workpad that include images, text, charts, and more. You can create your own elements and connect them to your data sources, add saved objects, and add your own images. | ||
|
|
||
| [float] | ||
| [[create-canvas-element]] | ||
| ==== Create an element | ||
|
|
||
| Choose the type of element you want to use, then connect it to your own data. | ||
|
|
||
| . Click *Add element*, then select the element you want to use. | ||
| + | ||
| [role="screenshot"] | ||
| image::images/canvas-element-select.gif[Canvas elements] | ||
|
|
||
| . To familiarize yourself with the element, use the preconfigured data demo data. | ||
| + | ||
| By default, most of the elements you create use demo data until you change the data source. The demo data includes a small data set that you can use to experiment with your element. | ||
|
|
||
| . To connect the element to your data, select *Data*, then select one of the following data sources: | ||
|
|
||
| * *{es} SQL* — Access your data in {es} using SQL syntax. For information about SQL syntax, refer to {ref}/sql-spec.html[SQL language]. | ||
|
|
||
| * *{es} documents* — Access your data in {es} without using aggregations. To use, select an index and fields, and optionally enter a query using the <<lucene-query,Lucene Query Syntax>>. Use the *{es} documents* data source when you have low volume datasets, to view raw documents, or to plot exact, non-aggregated values on a chart. | ||
|
|
||
| * *Timelion* — Access your time series data using <<timelion,Timelion>> queries. To use Timelion queries, you can enter a query using the <<lucene-query,Lucene Query Syntax>>. | ||
|
|
||
| Each element can display a different data source. Pages and workpads often contain multiple data sources. | ||
|
|
||
| [float] | ||
| [[canvas-add-object]] | ||
| ==== Add a saved object | ||
|
|
||
| Add <<managing-saved-objects,saved objects>> to your workpad, such as maps and visualizations. | ||
|
|
||
| . Click *Add element > Add from Visualize Library*. | ||
|
|
||
| . Select the saved object you want to add. | ||
| + | ||
| [role="screenshot"] | ||
| image::images/canvas-map-embed.gif[] | ||
|
|
||
| . To use the customization options, click the panel menu, then select one of the following options: | ||
|
|
||
| * *Edit map* — Opens <<maps,Maps>> or <<create-panels,Dashboard>> so that you can edit the original saved object. | ||
|
|
||
| * *Edit panel title* — Adds a title to the saved object. | ||
|
|
||
| * *Customize time range* — Exposes a time filter dedicated to the saved object. | ||
|
|
||
| * *Inspect* — Allows you to drill down into the element data. | ||
|

| == Automated Accessibility Testing | ||
|
|
||
|
|
||
| To write an accessibility test, use the provided accessibility service `getService('a11y')`. Accessibility tests are fairly straightforward to write as https://github.com/dequelabs/axe-core[axe] does most of the heavy lifting. Navigate to the UI that you need to test, then call `testAppSnapshot();` from the service imported earlier to make sure axe finds no failures. Navigate through every portion of the UI for the best coverage. | ||
|
|
||
| An example test might look like this: | ||
| [source,js] | ||
| ---- | ||
| export default function ({ getService, getPageObjects }) { | ||
| const { common, home } = getPageObjects(['common', 'home']); | ||
| const a11y = getService('a11y'); /* this is the wrapping service around axe */ | ||
| describe('Kibana Home', () => { | ||
| before(async () => { | ||
| await common.navigateToApp('home'); /* navigates to the page we want to test */ | ||
| }); | ||
| it('Kibana Home view', async () => { | ||
| await retry.waitFor( | ||
| 'home page visible', | ||
| async () => await testSubjects.exists('homeApp') | ||
| ); /* confirm you're on the correct page and that it's loaded */ | ||
| await a11y.testAppSnapshot(); /* this expects that there are no failures found by axe */ | ||
| }); | ||
| /** | ||
| * If these tests were added by our QA team, tests that fail that require significant app code | ||
| * changes to be fixed will be skipped with a corresponding issue label with more info | ||
| */ | ||
| // Skipped due to https://github.com/elastic/kibana/issues/99999 | ||
| it.skip('all plugins view page meets a11y requirements', async () => { | ||
| await home.clickAllKibanaPlugins(); | ||
| await a11y.testAppSnapshot(); | ||
| }); | ||
| /** | ||
| * Testing all the versions and different views of of a page is important to get good | ||
| * coverage. Things like empty states, different license levels, different permissions, and | ||
| * loaded data can all significantly change the UI which necessitates their own test. | ||
| */ | ||
| it('Add Kibana sample data page', async () => { | ||
| await common.navigateToUrl('home', '/tutorial_directory/sampleData', { | ||
| useActualUrl: true, | ||
| }); | ||
| await a11y.testAppSnapshot(); | ||
| }); | ||
| }); | ||
| } | ||
| ---- | ||
|
|
||
| === Running tests | ||
| To run the tests locally: | ||
|
|
||
| [arabic] | ||
| . In one terminal window run | ||
| `node scripts/functional_tests_server --config test/accessibility/config.ts` | ||
| . In another terminal window run | ||
| `node scripts/functional_test_runner.js --config test/accessibility/config.ts` | ||
| . In one terminal window run: | ||
| + | ||
| [source,shell] | ||
| ----------- | ||
| node scripts/functional_tests_server --config test/accessibility/config.ts | ||
| ----------- | ||
|
|
||
| . When the server prints that it is ready, in another terminal window run: | ||
| + | ||
| [source,shell] | ||
| ----------- | ||
| node scripts/functional_test_runner.js --config test/accessibility/config.ts | ||
| ----------- | ||
|
|
||
| To run the x-pack tests, swap the config file out for | ||
| `x-pack/test/accessibility/config.ts`. | ||
|
|
||
| After the server is up, you can go to this instance of {kib} at | ||
| `localhost:5620`. | ||
|
|
||
| The testing is done using https://github.com/dequelabs/axe-core[axe]. | ||
| The same thing that runs in CI, can be run locally using their browser | ||
| plugins: | ||
| You can run the same thing that runs CI using browser plugins: | ||
|
|
||
| * https://chrome.google.com/webstore/detail/axe-web-accessibility-tes/lhdoppojpmngadmnindnejefpokejbdd?hl=en-US[Chrome] | ||
| * https://addons.mozilla.org/en-US/firefox/addon/axe-devtools/[Firefox] | ||

|
|
||
| === Anatomy of a failure | ||
|
|
||
| Failures can seem confusing if you've never seen one before. Here is a breakdown of what a failure coming from CI might look like: | ||
| [source,bash] | ||
| ---- | ||
| 1) Dashboard | ||
| create dashboard button: | ||
| Error: a11y report: | ||
| VIOLATION | ||
| [aria-hidden-focus]: Ensures aria-hidden elements do not contain focusable elements | ||
| Help: https://dequeuniversity.com/rules/axe/3.5/aria-hidden-focus?application=axeAPI | ||
| Elements: | ||
| - #example | ||
| at Accessibility.testAxeReport (test/accessibility/services/a11y/a11y.ts:90:15) | ||
| at Accessibility.testAppSnapshot (test/accessibility/services/a11y/a11y.ts:58:18) | ||
| at process._tickCallback (internal/process/next_tick.js:68:7) | ||
| ---- | ||
|
|
||
|
|
||
| * "Dashboard" and "create dashboard button" are the names of the test suite and specific test that failed. | ||
| * Always in brackets, "[aria-hidden-focus]" is the name of the axe rule that failed, followed by a short description. | ||
| * "Help: <url>" links to the axe documentation for that rule, including severity, remediation tips, and good and bad code examples. | ||
| * "Elements:" points to where in the DOM the failure originated (using CSS selector syntax). In this example, the problem came from an element with the ID `example`. If the selector is too complicated to find the source of the problem, use the browser plugins mentioned earlier to locate it. If you have a general idea where the issue is coming from, you can also try adding unique IDs to the page to narrow down the location. | ||
| * The stack trace points to the internals of axe. The stack trace is there in case the test failure is a bug in axe and not in your code, although this is unlikely. |
