Write one failing test for a single behavior (red), write the minimal code to make it pass (green), then refactor while keeping tests green. Repeat per behavior rather than writing all tests upfront, which produces tests coupled to imagined structure.
Good tests verify observable behavior through public interfaces and survive internal refactors. Bad tests mock internal collaborators, test private methods, or assert on call counts, breaking whenever implementation changes without behavior changing.
Mock only at system boundaries like external APIs, databases, time, and file systems. Never mock your own classes or internal collaborators; in this codebase, randomness is handled by seeding the splitmix64 RNG rather than mocking.
Require red before green: a new test must fail before implementation exists. When adding tests around working code, briefly break the implementation and confirm the test goes red, then restore it.
No. Horizontal slicing produces tests of imagined behavior that pass when behavior breaks. Use vertical tracer bullets: one test, one minimal implementation, repeated so each test responds to what the previous cycle revealed.
