The Playwright Playbook — Part 3: Multi-User, Multi-Tab & Browser Context Testing

"Most frameworks test one user at a time. Real apps don't work that way."

In Part 1, we built the full foundation — POM, storageState, fixtures, and a clean project structure. In Part 2, we took control of the network layer — mocking APIs, simulating failures, and asserting on real network calls.

Now we tackle the scenario that breaks most automation frameworks.

Multiple users. Simultaneously. In one test.
