Hi Ramona,
Suppose, you have an OldTest keyword test. To copy the test, follow the steps below:
1. Right-click the OldTest node in the Project Explorer panel and select Save As from the context menu.
2. In the ensuing dialog, specify a new name for the test (for example, NewTest) and press Save. TestComplete will display the copied NewTest test in the Project Explorer panel.
3. Add the old test to the project. Right-click the KeywordTests node in the Project Explorer and select Add | Existing Item from the context menu. In the ensuing dialog, select the OldTest.tcKDTest file and press Open.
Now you can view both tests (OldTest and its copy - NewTest) under the KeywordTest node.
