This repository contains code examples of JUnit 5 for the book Mastering Software Testing with JUnit 5, authored by Boni Garcia and published by Packt. These examples covers 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 frameworks and 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 (test framework for web applications).
- Appium (driver for mobile devices).
- Android (open source mobile operating system based on Linux).
- REST services (using REST Assured, Retrofit2, or WireMock).
