Next-Gen Testing Tools for Java

" summary

Covers concrete tools and results: JQwik property-based testing generates thousands of inputs, finds a failing case at the 71st try and shrinks it to a minimal seed (e.g. -2147483648); PITest mutation testing flips conditionals to ensure tests fail when code is mutated; Testcontainers with Postgres 14.5 spins real Docker databases (and Testcontainers Cloud) to run integration DAO tests that actually persist and retrieve students; Awaitility polling handles async waits; Rest-Assured, MockServer/WireMock and AssertJ round out API and assertion workflows.
