# Run tests and next steps


## Run the tests

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

Or with Gradle:

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

You should see the WireMock Docker container start in the console output. It
acts as the photo service, serving mock responses based on the configured
expectations. All tests should pass.

## Summary

You built a Spring Boot application that integrates with an external REST API,
then tested that integration using three different approaches:

- WireMock JUnit 5 extension with inline stubs
- WireMock JUnit 5 extension with JSON mapping files
- Testcontainers WireMock module running WireMock in a Docker container

Testing at the HTTP protocol level instead of mocking Java methods lets you
catch serialization issues and simulate realistic failure scenarios.
