Spring Boot Unit Testing with JUnit, Mockito and MockMvc

Develop Real-Time Spring Boot Unit Tests: JUnit, Mockito, MockMvc, TDD, JsonPath, Hamcrest, H2 Embedded DB, MySQL

Spring Boot is the most popular framework for building enterprise Java applications. Spring Boot includes testing support to develop unit tests and integration tests using JUnit, Mockito and MockMvc. By developing tests, you can create applications with better code design, fewer bugs, and higher reliability. This course shows you how to take full advantage of Spring Boot's testing support.

You will also use modern development tools such as IntelliJ (free version) and Maven. All of the projects are based on Maven, so you are free to use any IDE tool that you want.
