Property to create-drop to let Hibernate generate If this is not the case, we must disable Flyway Only then do we knowĪt test time that the flyway scripts work as expected.Īs long as the scripts contain SQL that is valid on both the productionĭatabase and the in-memory database used in the tests (an H2 database Use it in our JPA tests as described above. If we're using Flyway in production it's really nice if we can also The following log output confirms that the file has been executed: If we set it to always, it will always execute. Meaning it will only execute for an embedded database (i.e. We can control whether the schema.sql file should be executed with the property This overrides the ddl-auto configuration of Hibernate If Spring finds a schema.sql file in the classpath, this will be executed against Spring Boot supports executing a custom schema.sql file So, if we’re happy with Hibernate creating the schema for us, we don’t Meaning that the schema is created before running the tests and auto, which Spring Boot sets to create-drop by default, Using Hibernate’s ddl-autoīy default, will configure Hibernate to create the database Let’s look at some different ways to do this. Creating the Database Schemaīefore we can test any queries to the database, we need to create an This way, the database state stays pristine between testsĪnd the tests stay independent of each other. Runs in its own transaction, which is rolled back after the method This is why, by default, each test method Note that by default the application context containing all theseĬomponents, including the in-memory database, is shared between all “real” database we might have configured in application.properties To point to an embedded, in-memory database instead of the We can, for instance, inject a DataSource, our test class if we need them.Īlso, we can inject any of the Spring Data repositories from our application.Īll of the above components will be automatically configured Of it containing the components needed to initialize any JPA-relatedĬomponents like our Spring Data repository. Needed for our Spring Boot application, but instead only a “slice” Spring Boot test annotations like so created application context will not contain the whole context Load the SpringExtension because it's included as a meta annotation in the As of Spring Boot 2.1, we no longer need to That matter, Spring Boot provides the We can just add it to our unit test and it will set upĪ Spring application code examples in this tutorial use the annotation to tell To test Spring Data JPA repositories, or any other JPA-related components for In a docker container that is set up on-demand in the continuous integration Have to provide a real database in the background (for instance Might not work with the embedded in-memory database, so we would If they really use database-specific SQL, those tests So, native queries are prime candidates for integration tests. Since the query may containĭatabase-specific SQL, there’s no way Spring Data or Hibernate It’s important to note that neither Hibernate nor Spring Data Instead of specifying a JPQL query, which is an abstraction over SQL, we’re UserEntity findByNameNativeQuery ( ( "name" ) String name ) Value = "select * from user as u where u.name = :name" , We’re using JUnit Jupiter as our testing framework and In this tutorial, aside from the usual Spring Boot dependencies, Testing Spring MVC Web Controllers with Testing JPA Queries with Spring Boot and Integration Tests with you like learning from videos, make sure to check out Philip’s Testing Spring Boot Applications Masterclass (if you buy through this link, I get a cut).This article is accompanied by a working code example on GitHub. In this tutorial, we’ll first discuss which types of queries are worthy of tests and thenĭiscuss different ways of creating a database schema and database state to test against. With the annotation, Spring Boot provides a convenient way to set upĪn environment with an embedded database to test our database queries against. Aside from unit tests, integration tests play a vital role in producing quality software.Ī special kind of integration test deals with the integration between our code
