How to one-off run @DataJpaTest against real database instead of in-memory with Spring Boot

Question

I am using Spring Boot 1.4.3 and have a whole bunch of tests that are annotated with @DataJpaTest . By default, they run against an in-memory database. I would like to be able to run all of them against a local MySQL temporarily. How can I do this in an easy way?

I have found that I can make it work for one by adding @ActiveProfiles("local") where I have an application-local.properties that points to my local MySQL, but it is just too much work to add that everywhere, run the tests and then remove it again (since I only want to run this manually against MySQL, the CI environment will run against the in memory db).

I am using Maven if that would matter.

UPDATE:

So I have an application-local.properties which contains the db properties to connect to my local MySQL database (Which I use already to run my application against the local MySQL)

Then I right-click in IntelliJ on a package and select "Run all tests in package". In the settings of that run configuration, I add -Dspring.profiles.active=local to the "VM options" field.

I would have thought that this would activate the local profile during the tests, but it does not. If I stop the local MySQL, the tests still run fine.

Answer 1

In the docs it states that you are able to remove the autoconfigured h2 datasource with @AutoConfigureTestDatabase(replace= Replace.NONE) on the test class https://docs.spring.io/spring-boot/docs/1.4.2.RELEASE/reference/html/boot-features-testing.html#boot-features-testing-spring-boot-applications-testing-autoconfigured-jpa-test .

Also you then need to provide your db setup in properties, so that it does not use your app properties eg:

# Database
spring.datasource.url=jdbc:mariadb://localhost:3303/test
spring.datasource.username=test
spring.datasource.password=test
spring.datasource.driver-class-name=org.mariadb.jdbc.Driver
spring.jpa.hibernate.ddl-auto=none
spring.jpa.show-sql=true

i put this in application.properties in the test package

Answer 2

You can add the profile with the MySQL datasource properties in the same application.properties (or .yml) as:

application.yml

# Existing properties

---
spring:
  profiles: h2
# More h2-related properties

---
spring:
  profiles: postgres
  database:
    driverClassName: org.postgresql.Driver
  datasource:
    url: jdbc:postgresql://localhost:5432/db_dvdrental
    username: user_dvdrental
    password: changeit
  jpa:
    database: POSTGRESQL
    generate-ddl: false
# More postgres-related properties

and either use @ActiveProfiles("postgres") in an integration test class or start teh container using VM argument as:

java -Dspring.profiles.active=h2 ...

Answer 3

1. Add application.yml(properties) with jdbc connection into src/test/resources

2. Run your JPA test with @AutoConfigureTestDatabase(replace= AutoConfigureTestDatabase.Replace.NONE) - it disables using embedded database (h2), otherwise :

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource': Invocation of init method failed; nested exception is java.lang.IllegalStateException: Failed to replace DataSource with an embedded database for tests. If you want an embedded database please put a supported one on the classpath or tune the replace attribute of @AutoConfigureTestDatabase.
