How do I troubleshoot my iOS unit tests?

I'm having trouble with my iOS unit tests failing. What should I check first?

First, check the error messages in the test results. They often provide clues about what's going wrong.

I see an error related to a nil value. How can I debug that?

You can use breakpoints to inspect the values of variables at runtime. Make sure your objects are initialized properly.

What if the tests pass on my local machine but fail on CI?

This could be due to environment differences. Check your CI configuration and ensure all dependencies are correctly set up.

Any tips for writing more reliable unit tests?

Yes! Focus on isolating your tests, use mocks for dependencies, and ensure your tests are deterministic.
