Wait for TestComplete Step to end

Hello CristianE,

I'm sorry you're running into this issue. I have found that it works more effectively to call your ReadyAPI project from TestComplete instead of the inverse. When you build your TestComplete test to prepare your environment, you can call the .xml file associated with your ReadyAPI project to execute the testcase. TestComplete will generate reports to the location of your choosing and include the API testresults in the test logs. 

Let me know if this suggestion is helpful.
