wiremock-spring-boot with a BDD Cucumber step definition

[corstad]

I have successfully used this library for a @SpringBootTest. I am now trying to utilize it on a Spring Boot Cucumber test and am having issues. The @InjectWireMock isn't being wired for the test.

Has anyone been able to use this library with a Spring Boot Cucumber test?

Can you publish somewhere a sample that does not work?

@maciejwalkowiak In cucumber with Spring Boot you have a class which define the runtime context for Cucumber Test. It is on this class you put the annotation @EnableWireMock. Like following :

@SpringBootTest(webEnvironment = RANDOM_PORT)
@CucumberContextConfiguration
@EnableWireMock({
        @ConfigureWireMock(name = "my-service", property = "application.url"),
        @ConfigureWireMock(name = "positions-service", property = "position.url"),
        @ConfigureWireMock(name = "crm-service", property = "crm.url")
})
@Testcontainers
public class BootstrapCucumberContextConfiguration {

After that I try to inject defined Wiremock server into Step class as we do for Spring Bean :

public class Steps  {
    @Autowired
    private BeanInterface bean;
    @InjectWireMock("my-service")
    private WireMockServer myService;

    @Given("my step...")
    public void step1() {
        myService.stubFor(...);
    }

When you run this configuration you end up with a null myService which provoque a NullPointerException (of course).

In addition, Cucumber use the suite Junit 5 feature through the annotation @Suite and its own engine. From my minimalist comprehension of Junit5. Running a TestSuite with a custom engine doesn't seem to "launch" extensions. So the WireMockSpringExtension can not inject wiremock server in classes in the test context.

[McKratt]

Confirmed ! Custom Engine doesn't use Extension. Only the Jupiter platform Engine use Extensions

I don't think this is going to work. @InjectWireMock looks only at test classes hierarchy. Perhaps if it would be added as a Spring Bean, you could inject it, but at least at the time when I was designing this library I figured that it creates more noise than needed. Which, may not be true after all.
