Testing is a critical aspect of software development, and maintaining a clean test environment ensures accurate and reliable results.
To set up the test environment, include the necessary dependencies in your pom.xml, such as spring-boot-starter-data-jpa, spring-boot-starter-test, and hsqldb.
This article explores how to effectively manage database states in tests, focusing on how to set up and tear down Java HSQLDB databases.
The article explores the following solutions: Using spring.jpa.hibernate.ddl-auto and @DirtiesContext to reload the application context. Using @Sql annotation to reset the database state after every test with custom SQL scripts.
The spring.jpa.hibernate.ddl-auto=create-drop ensures the database schema is recreated for each test suite.
This approach uses the hibernate.hbm2ddl.auto property to recreate the schema on application startup and the @DirtiesContext annotation to reload the Spring context after each test.
The @Sql annotation provides a way to execute custom SQL scripts before or after each test.
When the application is executed, the test suite runs all the defined test cases, ensuring the database behaves as expected.
From leveraging hibernate.hbm2ddl.auto with @DirtiesContext for schema recreation to employing @Sql annotations with custom scripts for flexible cleanup, each method offers unique benefits tailored to specific use cases.
