I5 · REST Assured ↔ Playwright: After finishing GROUP H and I, as a Java developer you should ask: to test `/api/v1/bugs`, REST Assured or Playwright?
After finishing GROUP H and I, as a Java developer you should ask: to test `/api/v1/bugs`, REST Assured or Playwright? The answer starts with "both", but the WHY matters: REST Assured stays INSIDE the Java ecosystem and directly shares the `Bug` POJO (H3), `RequestSpecification` (H5), and JUnit/TestNG reporting (H6) — if your team lives in Java with Selenium/REST Assured, the friction is near ZERO. Playwright lives in TypeScript and provides I3's hybrid power (API+UI in the SAME file) — if the team already writes UI tests with Playwright, keeping API tests in the SAME TypeScript project instead of moving them to a separate Java project (REST Assured) provides consistency. This is not "which is better", it is the **"which language/ecosystem does the team live in"** question — just like the Express/Nest decision in C6/D5. **For a deep Playwright guide → see the `/playwright` page.**
The Same Test, in Two Languages
🎬 The Same Bug, Two Test Ecosystems
Playwright (TypeScript)
The team's language decides
The same `GET /api/v1/bugs/42` request will be tested in two different ecosystems.
REST Assured: `given/when/then`, the `Bug` POJO, a JUnit report — INSIDE the Java ecosystem.
Playwright: `request`/`expect`, switching to `page` for UI in the SAME file — INSIDE the TypeScript ecosystem.
The lesson — both correctly test the SAME endpoint; the choice is not "which is better", it depends on "which language the team lives in, is hybrid power or Java ecosystem integration the priority".
The Order for Choosing the Right Tool
Look at the team's ecosystem…
Does the team already work in Java/Selenium or TypeScript/Playwright?
Ask about hybrid needs…
Is API+UI needed in the same file (I3), or is pure API testing enough?
