What are test dependencies and why are they important?

Test dependencies refer to the relationships between different tests and the components they rely on. They are crucial because they help ensure that tests run in the correct order and that the necessary conditions are met for each test to execute successfully.

Can you give me an example of a test dependency?

Sure! For instance, if you have a test that verifies user login functionality, it may depend on a test that sets up a user account. If the account setup test fails, the login test will also fail, even if the login functionality itself is working.

How can I manage test dependencies effectively?

You can manage test dependencies by using test frameworks that support dependency management, organizing tests into suites, and ensuring that setup and teardown processes are well-defined.

What happens if I ignore test dependencies?

Ignoring test dependencies can lead to unreliable test results, as tests may fail due to unmet conditions rather than actual issues in the code. This can waste time and resources during the testing process.
