This repository contains the code examples of JUnit 5 for the book Mastering Software Testing with JUnit 5, authored by [Boni García] and published by Packt.

These examples cover the main features of JUnit 5, such as:

  • JUnit 5 tests lifecycle.
  • Assertions.
  • Tagging and filtering tests.
  • Conditional test execution.
  • Nested and repeated tests.
  • Migration from JUnit 4.
  • Dependency injection.
  • Dynamic tests.
  • Test interfaces.
  • Test templates.
  • Parameterized tests.
  • Parallel execution.
  • Ordered tests.

Moreover, the integration with third-party technologies is also illustrated with examples, concretely:

  • Mockito (popular mock framework).
  • Spring (Java framework aimed to created enterprise applications based on dependency injection).
  • Docker (container platform technology).
  • Selenium WebDriver (test automation library for web applications).
  • Appium (test automation library for mobile devices).
  • Android (open source mobile operating system based on Linux).
  • REST services (using REST Assured, Retrofit2, or WireMock).
