Learning Test-Driven Development • Saleem Siddiqui & Dave Farley

Learn the principles and best practices of Test-Driven Development (TDD) with experts Saleem Siddiqui and Dave Farley. Discover how TDD can drive good design, catch errors early, and improve code maintainability and reliability.

Key takeaways

Ensure your state machine logic is idempotent and unaffected by external changes.
Test-driven development is a means to an end, not an end unto itself.
The goal of testing is to get fast feedback and move quickly, rather than writing comprehensive tests.
TDD is not just about writing unit tests, but about writing good design.
The act of writing a test can help drive the design of the code.
The red-green-refactor cycle is a key aspect of TDD, allowing for incremental and rapid progress.
TDD can be used to write more maintainable and reliable code.
TDD is a discipline that requires effort and practice to develop, but the benefits are well worth it.
There is no one “right” way to do TDD, and different approaches can be effective.
The most important thing is to find an approach that works for you and your team.
The emphasis on fast feedback and continuous testing is important, as it allows for rapid iteration and improvement.
The power of TDD lies in its ability to drive the design of the code and catch errors early on.
TDD is not a panacea, but it can be a powerful tool in a developer’s toolkit.
