30+ curated questions with the same answer shape every time: quick recap, deep dive, pitfalls, and follow-ups. Coverage includes unit testing basics, tdd practices, mocking with mockito, integration testing, and more.
Suggested path
Topics follow a teaching order. Each answer ends with a clear Next question control so you can move forward without hunting the list.
Testing interviews test whether you understand testing as a strategy, not just whether you write tests. This module is an elevation arc: it opens with unit-testing basics and TDD (the foundation), then Mockito (the mocking tool every Java test uses). Integration testing and Spring Boot testing are the framework tier, then Testcontainers (the modern integration approach). Testing strategies, automation, and contract testing follow, then the specialized tiers — performance, chaos. Unit-testing advanced closes the depth tier, then comparisons and scenario-based questions.

Numbers 1–30 follow the order we recommend — click any row to open the full answer, or use the sticky Next link at the bottom of each page to go Q1 → Q30.
Interviewers rarely ask Java Testing in isolation. These are the modules that most often come up in the same loop.
