How are measurements calculated for SoapUI Tests?
Credit consumption for SoapUI tests is calculated based on the number of HTTP requests the test generates, not by the number of Steps in the Test Case.
For example, see the attached image from a TestCase in ReadyAPI. This test case makes an HTTP call in step 1, then uses Groovy to capture Headers from the response in step 2, and then makes a 2nd HTTP request in step 3. This test uses only 2 measurements, despite having 3 steps. This is because the 2nd step in the TestCase does not generate an HTTP request.
