How can I debug XCTests that are failing?

I'm facing some XCTest failures in my iOS app. How can I debug them?

Debugging XCTests can be tricky. First, check the error messages in the test report. What specific errors are you seeing?

The error says 'unexpectedly found nil while unwrapping an Optional'. What does that mean?

This error usually means you're trying to access a value that is nil. Check your code to ensure that the variable is initialized before use.

How can I find out where the nil value is coming from?

You can set breakpoints in your code to inspect the values of your variables at runtime. This will help you identify the source of the nil.

Thanks! Any tips for writing better tests to avoid these issues?

Absolutely! Make sure to use optional binding and provide default values. Also, consider using XCTest assertions to validate your assumptions.
