out: Run a new load test

Parameters

  • plan: The path to load test file.
  • data: The path to load test data.
  • pods: Number of distributed pods for the load test.
  • overwrite: Overwrite the load test if exists. Possible values: true or false
  • type: Load test type.
Optional
  • vars: The path to environment variables file.

Those parameters will be used to create load test with this API call.

The load test will be tagged with tags in source configuration plus current timestamp in nanoseconds (in order to sort the versions).

curl -X POST http://${KANGAL_PROXY_ADDRESS}/load-test \
  -H 'Content-Type: multipart/form-data' \
  -F distributedPods=${pods} \
  -F testFile=@${plan} \
  -F testData=@${data} \
  -F tags=${tags} \
  -F type=${type} \
  -F overwrite=${overwrite} \
  -F envVars=@${vars}
