If a script causes an error, TC will either terminate the test run or just go on, depending on the "stop on error" option. In both cases, trying to find the cause of the error is very time consuming...
Hello,
TestComplete has a special method that allows pausing script execution at a desired point - Runner.Pause. Documentation on this method can be found in the Pause Method help topic. This method can be called in the test code itself as well as in the OnLogError event handler code.
So, generally the requested functionality exists in TestComplete.
