Testcontainers<\/a> is a Java library that allows integrating Docker containers in JUnit tests with ease. In a Containerized World<\/em>, there is little sense to complicate the tests configuration with embedded databases and services. Instead, use run your services in Docker and let the Testcontainers manage this for you. So if you are need Redis, MongoDB or PostgreSQL in your tests – Testcontainers may become your good friend.<\/p>\n

In this blog post you will learn how to configure Testcontainers to manage PostgreSQL instance in Quarkus integration tests.<\/p>\n

Dependencies<\/h2>\n

In order to use Testcontainers with PostgreSQL you need to add the following dependencies to the pom.xml<\/code>:<\/p>\n

<dependency>\n    <groupId>org.testcontainers<\/groupId>\n    <artifactId>testcontainers<\/artifactId>\n    <version>1.12.5<\/version>\n    <scope>test<\/scope>\n<\/dependency>\n<dependency>\n    <groupId>org.testcontainers<\/groupId>\n    <artifactId>postgresql<\/artifactId>\n    <version>1.12.5<\/version>\n    <scope>test<\/scope>\n<\/dependency><\/pre>\n
Note: Testcontainers provides JUnit 5 plugin, but in the scenario presented in this article it is not needed.<\/p>\n
Test datasource configuration<\/h2>\n
The default PostgreSQL configuration in Quarkus application may look like below:<\/p>\n
quarkus.datasource.url=jdbc:postgresql:\/\/localhost:5432\/some-db\nquarkus.datasource.driver=org.postgresql.Driver\nquarkus.datasource.username=user\nquarkus.datasource.password=password<\/pre>\n
By default, this configuration will be used in any active profile. The built-in profiles in Quarkus are: dev<\/code>, prod<\/code> and test<\/code>. The test<\/code> profile will be used every time you run the @QuarkusTest<\/code>.<\/p>\n
You can adjust test<\/code> profile by providing the %test.<\/code> prefix to the configuration properties in src\/main\/application.properties<\/code> file. This allows to configure (and launch) PostgreSQL database container via JDBC URL scheme<\/strong>. To achieve this make sure to:<\/p>\n
