Guidance for Spring Boot TDD covering JUnit 5, Mockito, MockMvc, Testcontainers, JaCoCo and coverage enforcement, ideal for adding endpoints, fixing bugs, or refactoring with high confidence.

Provision enterprise-grade Playwright Java tests with a Page Object Model scaffold, JUnit 5 workflows, thread-safe parallel runs, Allure reporting, CI-friendly setup, and hybrid API/UI coverage to fix flakes and scale browsers.

This guide provides comprehensive best practices for writing robust and effective unit tests using JUnit 5 in Java. It covers standard test structures (Arrange-Act-Assert), advanced data-driven testing using parameterized methods, best assertion practices (including AssertJ), and dependency isolation using mocking frameworks like Mockito. Ideal for developers aiming to improve code coverage and test reliability.

A comprehensive guide and generator for writing robust, production-grade unit and integration tests using JUnit 5 in Java. It covers advanced features like parameterized tests, Mockito mocking, lifecycle management, and nested test structures. Use this skill when you need to write clean, reliable, and highly structured Java test suites.

A comprehensive guide to Test-Driven Development (TDD) for Quarkus 3.x LTS, focusing on event-oriented architectures. This framework utilizes JUnit 5, Mockito, REST Assured, Apache Camel, and JaCoCo to ensure high code coverage (80%+). Use it when developing new features, fixing bugs, or refactoring event-driven services and API endpoints.

This comprehensive guide details the complete Test-Driven Development (TDD) workflow for Spring Boot applications. It covers best practices for writing unit tests (JUnit 5, Mockito), web layer tests (MockMvc), integration tests (SpringBootTest), and persistence tests (DataJpaTest). It also instructs how to use Testcontainers for realistic database simulations and achieve high code coverage with JaCoCo, ensuring robust and maintainable codebases.

This skill generates production-grade JUnit 5 unit and integration tests in Java. It covers assertions, parameterized tests, lifecycle hooks, mocking with Mockito, and nested tests. Ideal for developers needing robust testing strategies and best practices for Java projects.

This skill enables developers to scaffold, write, and debug enterprise-grade Playwright E2E tests in Java. It enforces the Page Object Model, JUnit 5, and Allure reporting integration. Supports parallel execution, CI/CD pipelines, and thread-safe base classes for production-quality testing. Ideal for Java 17+ environments.
