Defining expected behavior with tests before modifying production code ensures expected outcomes are specified in advance. This reduces errors during development by validating that new changes pass automated or manual checks.

To verify a bug fix, define a test, fixture, or manual check to confirm the expected behavior. Run the check to see it fail for the expected reason, implement the code change, then rerun until it passes.

The best way to ensure behavior correctness is specifying expected outcomes through verification checks before editing the main codebase. This approach supports reliable development workflows by catching errors early.

Yes, you can use manual checks instead of automated tests. The verification process supports defining and running both automated tests and manual checks to validate software behavior before making changes.

You need to run a verification check during a development workflow whenever implementing a new feature or bug fix. Run it initially to confirm it fails for the expected reason, then rerun after modifying code until it passes.

Yes, this testing approach works for both new features and bug fixes. It facilitates defining verification checks to validate expected software behavior before implementing changes across various development workflows.
