Using static testing

Static testing involves carefully reviewing the code to think through its implications and possible issues. It lets you find bugs before the code is even run by highlighting edge cases that haven’t been handled and good coding practice. If your company already runs code reviews, check that they always consider these cases and testing.

In terms of the review types listed in Chapter 3, How to Run Successful Specification Reviews, this is an inspection, stepping in detail through the code to identify and solve technical problems by domain experts.

Static testing should review the unit tests, which are written alongside the code. Apply the ideas in this book to ensure the unit tests comprehensively verify the individual functions within each feature. The tests can even be written before the code as part of Test Driven Development (TDD). In TDD, the developer writes unit tests based on their proposed implementation, which initially fails. As they write...
