Spring Boot - Testing a MongoDB application with @DataMongoTest - Example
In this section, we will learn how to test Repository layer components with @DataMongoTest in Spring Boot application. 1. @ DataMongoTest Instead of bootstrapping the entire application context for every test, @DataMongoTest allows us to initialize the Spring application context with only those beans needed to test Data MongoDB-based components. By default, it scans for @Document classes and configures Spring Data MongoDB repositories. It will auto-configure MongoTemplate . If an embedded database is available on the classpath, @DataMongoTest will autoconfigure one for testing purposes. Regular @Component , @Service or @Controller beans are not scanned when using this annotation. This approach not only speeds up the testing process but also ensures a focused and efficient testing environment. This approach is also known as "slicing" the application context.
