// MISSION BRIEF

Your Mission

Flaky tests are not bad luck, they are undiagnosed bugs in the test (or occasionally the app). This drill covers the signatures: order dependence, network races, stale references, and the retry settings that hide versus reveal them.

Seven questions. Speed bonus active: quick, correct answers earn extra points.

// FIRST CONTACT

Battle teaser

A test passes when run alone via .only but fails in the full suite. Primary suspect:

  1. AThe test file is too long for the runner
  2. BLeaked state from earlier tests, backend data, uncleaned mocks, or storage that testIsolation does not cover (it resets browser state, not your database)
  3. C.only changes the assertion engine
  4. DSuite mode randomizes viewport sizes
Answers, scoring, hints, and the full battle stay sealed.
