Spring Boot - Testing Spring Data JDBC application with @DataJdbcTest - Example
In this section, we will learn how to test Repository layer components with @DataJdbcTest in Spring Boot application. 1. @ DataJdbcTest Instead of bootstrapping the entire application context for every test, @DataJdbcTest allows us to initialize the Spring application context with only those beans needed to test Spring Data JDBC-based components. It will auto-configure JdbcTemplate and if an embedded database is available on the classpath, @ DataJdbcTest will autoconfigure one for testing purposes. By default, tests annotated with @ DataJdbcTest are transactional and roll back at the end of each test, means we do not need to clean up saved or modified table data after each test. 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. Find the...
