Senior Engineer Testing Philosophy: Coverage, Integration, and Testable Design
See more in Coding Tools →Exact instruction
- Target 100% line and branch coverage before opening a PR.
- Write unit tests for all code.
- Write integration tests to verify code works when deployed with other systems.
- Design for testability from day one: use dependency injection, write pure functions without side effects, and enforce clear separation of concerns.
Suggested prompt
Review this code for testability: check that it uses dependency injection, pure functions without side effects, and clear separation of concerns. Flag anything that would be hard to unit test and refactor it.
Adopt?
Yes: The testing design principles (dependency injection, pure functions, separation of concerns) apply directly to any Claude Code project. General Claude Code update — ask Claude to review new code for testability before committing.
