Write the failing case first
A bug you are about to fix.
Shortregressiontdd
Write the failing test for this bug first. Nothing else yet, no fix.
Making it yours
- Paste your own material where the prompt asks for it. Everything above that line is instruction, not content.
- Delete any rule that does not apply to you. A shorter prompt that fits beats a thorough one that does not.
- If the answer comes back vague, add a line saying what you do not want. Constraints work better than encouragement.
Failing and flaky tests. Diagnosing a red run, stabilising a flake, and locking a fixed bug in with a regression test.
