test-strategy

From the author

Decide what to test and at which level before any tests get written — enumerate failure modes by consequence, give each one the cheapest level that can actually observe it, and name what is deliberately left uncovered. Use when starting testing on a feature or a codebase, when asked for a test plan or why coverage sits where it does, or when a suite is large and still missing bugs. Not for writing the tests themselves, and not for proving a finished change works.
