If you only need to test whether the server responds to specific requests, you can create a test from a single request. In this case, a functional test case will be created automatically.
Right-click the project in ReadyAPI and select Create Load Test, or click in the toolbar.
In the New Load Test dialog switch to the Manual tab and select the Single request option.
Select the request for which the load test will be created and enter a name of the new test and click OK.
ReadyAPI will first create a new functional test matching the request, and then create a new load test.
