How are your tests related to each other?

Tests are usually interconnected through shared data, dependencies, and execution order. For example, integration tests may use the results of unit tests, and end-to-end tests may rely on data prepared in previous steps. Automation often employs patterns such as the Page Object to reuse code and reduce duplication. Chains of tests can also be built, where one test checks basic functionality, and the next tests more complex scenarios based on the previous results.
