# Run Dependency

You can set a dependency of test cases within a test scenario. This means that if a single test case failed, none of the other test cases should be executed. To do so, use these buttons:

This enables you to set dependencies to marked test cases. In the following example, test case 2 will only be executed if test case 1 passed, and test case 3 will only be executed if test case 2 passed.
