What are common assertion errors in pytest?

Common assertion errors in pytest include AssertionError, ValueError, and TypeError. They usually occur when the expected result does not match the actual result.

Can you give me an example of an AssertionError?

Sure! An AssertionError occurs when an assert statement fails. For example, if you have assert 1 + 1 == 3, it will raise an AssertionError because the condition is false.

How can I debug these assertion errors?

You can debug assertion errors by using the -v option for verbose output, which shows detailed information about the failed assertions.

Are there any best practices to avoid these errors?

Yes, some best practices include writing clear and concise assertions, using fixtures for setup, and running tests frequently to catch errors early.
