TDD (Test-Driven Development)

Test-Driven Development: define expected behavior first, then make it pass with implementation.

Quick Reference

TDD Cycle

Define expected behavior → natural failure → implement → pass → refactor. See cycle.md.

Test Execution

Environment detection → impact scope → execution (unit→integration→e2e) → result reporting. See run.md.

Test Design Techniques

Decide which test cases to write (boundary value, equivalence partitioning, etc.). See test-strategies.md.
