TDD Test Generation

RGRC Cycle

Phase	Goal	Rule
Red	Failing test	Verify failure reason
Green	Pass test	"You can sin" - dirty OK
Refactor	Clean code	Keep tests green
Commit	Save state	All checks pass

Baby Steps (2-min cycle)

30s: Write failing test → 1min: Make pass → 10s: Run tests → 30s: Tiny refactor → 20s: Commit if green

Test Design

Technique	Use For	Example
Equivalence Partitioning	Group same behavior	Age: <18, 18-120
Boundary Value	Test edges	17, 18, 120, 121
Decision Table	Multi-condition logic	isLoggedIn × isPremium

Coverage

Level	Target	Focus
C0	90%	All lines executed
C1	80%	All branches taken

Naming

Level	Pattern
Suite	`describe("[Target]", ...)`
Group	`describe("[Method]", ...)`
Test	`it("when [condition], should [expected]", ...)`

Framework Detection

Condition	Framework
`vitest` in deps	Vitest
`jest` in deps	Jest
`bun` as runtime	Bun test
No framework found	Vitest
