# Run tests and next steps


## Run the tests

```console
$ ./mvnw test
```

Or with Gradle:

```console
$ ./gradlew test
```

You should see the Keycloak and PostgreSQL Docker containers start with the
realm settings imported and the tests pass. After the tests finish, the
containers stop and are removed automatically.

## Summary

The Testcontainers Keycloak module lets you develop and test applications using a
real Keycloak server instead of mocks. Testing against a real OAuth 2.0
provider that mirrors your production setup gives you more confidence in your
security configuration and token-based authentication flows.
