It's a best practice to reuse test cases.
For example, you can have only one Login test case and import it in all of your test suites.
When you select the
Import Test Case action, the
Test case to import dropdown gets populated with the entire list of test cases that you have access to.
You can only import test cases from other Web Tests in a Web Test.
You can only import test cases from other Mobile Tests in a Mobile Test.
When the test is executed, the
Import Test Case action executes the latest version of the imported test case.
The variables declared in the imported test case can be accessed from the test suite in which it gets imported.
