Start using Test Driven Development today is a post I wrote over on my company’s blog. It covers how TDD has improved my work since I started Helicoid Limited, and how you can start using TDD right now.
- Learn how to write basic tests in your chosen language – don’t worry about fully learning the test framework, start by copying examples
- When adding a new feature, start by creating tests first. Write code to satisfy these tests
- Refactor old code to work well with automated tests
- Write test data carefully and patiently, using this as a design technique for exploring the quality of your data modelling
- Find a mocking library so you can write encapsulated tests that don’t require external resources
- Find a tool for producing coverage reports in your chosen language
- Investigate automated testing triggered when deploying/releasing code
