More Examples

Random form data

<showFile("example/random-forms.json")>

{
  "baseUrl": "http://echo.jpillora.com",
  "duration": 5000,
  "connections": 1,
  "sequence": [
    { "method": "POST", "path": "/api/login",  "forms":[
        {"username":"foo","password":"bar"},
        {"username":"ping","password":"pong"},
        {"username":"zap","password":"zoop"}
      ]
    }
  ]
}

More response expectations

<showFile("example/expectations.json")>

{
  "baseUrl": "http://echo.jpillora.com",
  "runs": 3,
  "connections": 1,
  "sequence": [
    { "method": "GET", "path": "/api/code-test",  "expect": { "code": 408 } },
    { "method": "GET", "path": "/api/string-test",  "expect": { "contains": "abc" } },
    { "method": "GET", "path": "/api/regex-test",  "expect": { "match": "^a[Bb]c$" } }
  ]
}

runs is how many times to run the sequence. Can be used with or instead of duration.

Simulate load balancer

<showFile("example/load-balancer.json")>

{
  "baseUrls": [
    "http://74.125.237.114",
    "http://74.125.237.115",
    "http://74.125.237.116"
  ],
  "headers": {
    "host": "www.google.com.au"
  },
  "duration": 5000,
  "connections": 1,
  "sequence": [
    { "path": "/" }
  ]
}

Every request will randomly choose one of the baseUrls

Requests may also specify a header object which will override the job's header object
