Spock and Spring Boot example

This is an example of Spring Boot app tested with Spock framework.

• Spring Boot 1.5
• Spock 1.1

Component Test

• FooServiceSpec
• BarServiceSpec

These are component tests using the constructor mock injection.

Mark as a Spring Boot test without the web environment:

@SpringBootTest(webEnvironment = NONE)

Instantiate a service class with a mock dependency.

    @Subject BarService service

    ExternalApiClient client = Mock()

    def setup() {
        service = new BarService(client)
    }

Declare the mock interaction by Spock style:

        given:
        1 * client.getDefault() >> new Hello('world')

Integration Test

• FooControllerSpec
• BarControllerSpec

These are end-to-end tests using the test rest template. See also Testing improvements in Spring Boot 1.4.

Mark as a Spring Boot test with the real web environment:

@SpringBootTest(webEnvironment = RANDOM_PORT)

Import the mock configuration.

@Import(IntegrationTestConfiguration)

Use the TestRestTemplate to make a request.

    @Autowired
    TestRestTemplate restTemplate

Make a request to the target application:

        when:
        def entity = restTemplate.getForEntity('/foo', Hello)

Verify the response:

        then:
        entity.statusCode == HttpStatus.OK
        entity.body.name == 'world'
