You can call a Service Test test from a QuickTest test, and call a QuickTest test or action from a Service Test test. When the test runs, a single, combined report is generated with the results of all the actions and tests.
In Service Test, you can insert a special activity type that allows you to select a QuickTest test or action, which will run as part of the Service Test run.
Similarly, from QuickTest, you can add a call to a Service Test test, which will run as part of the QuickTest test run.
When the test runs, a single report is generated showing the results of all the tests and actions that ran, and their status.
