Model your first Test Case

There are two types of test cases in TPT - step list test cases and time partition test cases. The latter is a more advanced kind of test case.

Use step list modeling to create step list test cases.

Step list

A step list consists of one or more steps or actions. The steps are executed sequentially or even simultaneously.

To create a step list test case, right-click on the Test Cases folder in the Project view. Select Add test case (step list). Select the test case added.
