Other features

Support for authentication, cookie containers, and default credentials. It is possible to use the same credential configuration for multiple test cases. The credential configuration is specified by the CredentialConfigurationKey property.

{
  "CredentialConfigurations": [
    {
      "Key": "cred_1",
      "Provider": "NetworkCredentialProvider",
      "Data": {
        "username": "foo",
        "password": "bar"
      }
    }
  ]
}

Http request headers can be specified.

{
  "TestCaseConfigurations": [
    {
      "Name": "post_simple_1",
      "Uri": "http://localhost:3000",
      "HttpMethod": "POST",
      "NumberOfRequests": 10000,
      "FetchContent": false,
      "Parallelism": 500,
      "BoundedCapacity": 500,
      "Headers": {
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64)"
      },
      "Body": {

        "ContentType": "application/json",
        "Encoding": "utf-8"
      }
    }
  ]
}

Http request

Http requests created by WebBen are not actually sent to the server. Instead, they are stored in a queue. The queue is processed by multiple threads depending on the parallelism.

POST / HTTP/1.1
Host: localhost:3000
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) WebBen/1.2206
Content-Type: application/json; charset=utf-8
Content-Length: 15

{"name":"test"}

WebBen is just a simple tool to generate http requests. You can combine it with other tools to make more complex tasks. For example, you can use WebBen to generate requests and then use another tool to send them to the your backend.

Example

webben uri https://url-to-benchmark.local/pages/1 -e json | \
curl -H "Content-Type: application/json" \
    -X POST \
    --data-binary @- \
    https://your-awesome-backend.local/api/v1/posts
    

POST / HTTP/1.1
Host: your-awesome-backend.local
User-Agent: curl/7.79.1
Accept: */*
Content-Type: application/json
Content-Length: 1042
