Modern Testing Tools for Java Developers
summary
Five concrete tools with concrete wins: AssertJ replaces brittle field-by-field checks with recursive comparison, yields soft assertions and custom assertion classes so a failing object reports every differing field; OpenAPI + RestAssured generates client code (used across 13 teams) to shrink API test maintenance; Awaitility polls up to 10s to make async messaging tests reliable; WireMock runs persistent service-virtualization containers for shared stubs; PiTest (mutation testing) finds uncovered logic by mutating conditionals.
