With traditional software unit tests, there is never a guarantee that an application will actually function correctly in the production environment. When you add microservices to the mix, testing becomes even more intricate.

Testing Java Microservices is a comprehensive guide that teaches readers how to write various types of tests, including unit, component, integration, container, contract, chaos, and more. Throughout the book, it delves into technologies such as the Arquillian ecosystem, Wiremock, Mockito, AssertJ, Pact or Gatling. Moreover, it demonstrates how these testing techniques seamlessly integrate into the Continuous Delivery pipeline.

Key Features:
1. Practical Hands-On Guide: This book provides a hands-on approach to testing Java microservices, making it accessible to developers with a basic understanding of programming in Java. While experience with testing tools like jUnit is helpful, it is not mandatory. Some experience in Java EE, Spring, and Docker is also beneficial.
2. Writing Persistence Tests: The book emphasizes the importance of writing effective persistence tests, which ensure the reliability and consistency of data storage and retrieval in microservices. It covers techniques for testing databases, message queues, and other storage systems.
3. Teaching Test Strategies: Readers will gain insights into various test strategies, such as unit testing, integration testing, and end-to-end testing, and how they can be applied to microservices. The book provides guidance on test design, test automation, and test reporting.
4. Integrating into Continuous Delivery Pipeline: The book demonstrates how all the testing techniques discussed fit together into the Continuous Delivery pipeline. It explains the role of testing in the development and deployment process and how it can be integrated with other tools and processes.

A microservice can be a complex entity, consisting of several thousand lines of code or even several hundred thousand lines of code. Microservices enable programmers to isolate and scale smaller parts of an application, rather than the entire application as a whole. This modular approach allows for greater flexibility, scalability, and resilience in the face of changing requirements and environments.

In conclusion, Testing Java Microservices is an essential resource for developers who want to ensure the quality and reliability of their microservices-based applications. It provides practical guidance, hands-on examples, and insights into the latest testing techniques and technologies. Whether you are a seasoned tester or just starting your journey into microservices, this book will help you build robust and effective testing practices that contribute to the success of your software projects.
