// MISSION BRIEF

Your Mission

The suite takes 40 minutes and the release train leaves in 10. Parallelism is the answer, and also the reason your tests just started failing in ways they never did alone.

This quiz covers Playwright's execution model: workers, file-level vs test-level parallelism, serial mode, sharding, and merged reporting.

Battle teaser

Playwright's default parallelism model:

  1. AEverything runs serially unless you buy a license
  2. BParallelism only happens across different browsers
  3. CTest FILES run in parallel across worker processes; tests inside one file run in order in the same worker
  4. DEvery individual test always runs in parallel with every other
Answers, scoring, hints, and the full battle stay sealed.
