AutoCzar provides a feature of TestCase 'Reusability'.Any No. of Testcases can be called by just adding the Testcase as a TestStep in the main TestCase.
For example, we have two Testcases T1 and T2. If you want to call T2 in T1, select the action name column in the T1 Testcase, right click on T2 Testcase and select “Add to Test Step” option. Thus when you execute T1 Testcase, first the steps in the T1 will be executed and then the T2 Testcase. (Execution will be performed in the same order the Testcase is designed)
