Let's enhance the PricingService to report the cheaper price whenever the competitor has the same product in stock: The notify(String productName) method is void and hence we don't have to mock the return value of this call as it is not used for the execution flow of our implementation. pom.xml Is there a way to bypass the security? It creates a Mock for the EmployeeRepository, which can be used to bypass the call to the actual EmployeeRepository: Since the setup is done, the test case will be simpler: Our Controller depends on the Service layer; let's only include a single method for simplicity: Since we're only focused on the Controller code, it's natural to mock the Service layer code for our unit tests: To test the Controllers, we can use @WebMvcTest. AssertJ is another assertion library that allows you to write fluent assertions for Java tests. Testing Spring MVC Web Controllers with @WebMvcTest 3. Spring Boot applications are spring bases web applications. Furthermore, the ProductVerifier might also need other objects/resources/network/database to properly work, which would result in a test setup hell. It also provides annotations which help in integration testing as well. Also, you do not need to do that if you want to use H2.

A first test might require the ProductVerifier object to return true. The test cases for the integration tests might look similar to the Controller layer unit tests: The difference from the Controller layer unit tests is that here nothing is mocked and end-to-end scenarios will be executed. But if you define your own SpringTemplateEngine with your own settings, Spring Boot does not add one. For example, the Ruby on Rails web framework uses YAML to initialize a database with known parameters before running a test. It is the major and most used testing framework for Java. Practical Unit Testing with JUnit and Mockito. The JUnit assertEquals takes the expected value as a first argument and the actual value as the second argument, Hamcrest does it the other way around: The Hamcrest Matchers class exposes feature-rich matchers like contains(), isEmpty(), hasSize(), etc. The guides on building REST APIs with Spring.
