PUT /v2/tests/:test_id/run

When you create a test, it runs automatically (unless you scheduled it to run at some other time). You can run the same test again with this method. Make sure your validation files/DNS records are still in place.

curl -X PUT https://api.loader.io/v2/tests/f133e9e3691e405eefd3e1b7c351cb18/run \
     -H 'loaderio-auth: API_KEY'

Response:

{
    "message": "success",
    "result_id": "d745513b3d1e0689ab5f5e34525cc484",
    "status": "running",
    "test_id": "f133e9e3691e405eefd3e1b7c351cb18"
}

Each run generates a new result set with a unique result_id.
