        <dependency>            <groupId>org.testcontainers</groupId>            <artifactId>testcontainers</artifactId>            <version>1.5.1</version>            <scope>test</scope>        </dependency>        <dependency>            <groupId>org.slf4j</groupId>            <artifactId>slf4j-simple</artifactId>            <version>1.7.25</version>            <scope>test</scope>        </dependency>

The idea behind Test Containers is really simple. Since we're going to deploy our web service in a Docker container anyway, why not use a Docker container during our test as well? All you need to add is a @ClassRule. We create GenericContainer, we pass it to a Dockerfile, we pass ...
