Test Frameworks and Configuration Questions

Knowledge of how unit and integration test frameworks structure, configure, and run tests, illustrated across common frameworks (JUnit and TestNG in Java, pytest and unittest in Python, Jest and Mocha in JavaScript/TypeScript, Go's built-in testing package, RSpec in Ruby). Candidates should understand test lifecycle hooks (setup and teardown at the method, class, and suite level: for example JUnit's @BeforeEach/@AfterEach or TestNG's @BeforeMethod/@AfterMethod, pytest fixtures, Jest's beforeEach/afterEach) and how they define execution order. Coverage includes test grouping and filtering (tags, categories, markers, or include/exclude patterns), parameterized or data-driven tests (JUnit's @ParameterizedTest, TestNG's DataProvider, pytest's parametrize, table-driven tests in Go), handling test dependencies and ordering, parallel execution and thread or worker configuration, and expected-exception or error-assertion handling. Candidates should also know how to implement listeners, hooks, or custom reporters to capture test events and produce custom output, use assertion libraries effectively, and configure a framework's behavior via config files and build tool integration (for example pom.xml/build.gradle, pytest.ini/pyproject.toml, jest.config.js). Finally, assessors should evaluate understanding of the trade-offs between framework choices within a given language ecosystem and when to prefer one over another.
