I am writing a new app and trying to do BDD using cucumber and Spring Boot 1.4. Working code is as shown below:
@SpringBootApplication
public class Application {
I got it working with Spring Boot 1.5.x and 2.0 and then wrote a blog post to try to clarify this since it's tricky.
First, even if it's obvious, you need to have the right dependencies included in your project (being cucumber-spring
the important one here). For example, with Maven:
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-java</artifactId>
<version>2.3.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-junit</artifactId>
<version>2.3.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-spring</artifactId>
<version>2.3.1</version>
<scope>test</scope>
</dependency>
Now, the important part to make it work, summarized:
@RunWith(Cucumber.class
. @Given
, @When
, @Then
, etc.). @SpringBootTest
, @RunWith(SpringRunner.class)
and any other configuration you need to run your test with Spring Boot. For instance, if you're implementing an integration test without mocking other layers, you should add the webEnvironment
configuration and set it to RANDOM_PORT
or DEFINED_PORT
. See the diagram and the code skeleton below.
The entry point:
@RunWith(Cucumber.class)
@CucumberOptions(features = "src/test/resources/features/bag.feature", plugin = {"pretty", "html:target/cucumber"})
public class BagCucumberIntegrationTest {
}
The Spring Boot base test class:
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public abstract class SpringBootBaseIntegrationTest {
}
The step definitions class:
@Ignore
public class BagCucumberStepDefinitions extends SpringBootBaseIntegrationTest {
// @Given, @When, @Then annotated methods
}
This is what you need to make DI work. For the full code example, just check my blog post or the code in GitHub.
Prior to Spring Boot 1.4 you can use
@ContextConfiguration(classes = {YourSpringConfiguration.class}, loader = SpringApplicationContextLoader.class)
From Spring Boot 1.4 onwards SpringApplicationContextLoader is deprecated so you should use SpringBootContextLoader.class instead
Really just adding @SpringBootTest (with an optional configuration class) should work on its own, but if you look at the code in cucumber.runtime.java.spring.SpringFactory method annotatedWithSupportedSpringRootTestAnnotations it's not checking for that annotation, which is why simply adding that annotation in conjunction with @SpringBootTest works.
Really the code in cucumber-spring needs to change. I'll see if I can raise an issue as in the Spring docs it states that SpringApplicationContextLoader should only be used if absolutely necessary.I'll try and raise an issue for this for the cucumber spring support.
So as it stands stripwire's answer using a combination of @SpringBootTest and @ContextConfiguration is the best workaround.
I had the same problem. The comment from above directed me to the solution
The problematic code in cucumber-spring seems to be this github.com/cucumber/cucumber-jvm/blob/master/spring/src/main/…
After adding the annotation @ContextConfiguration
the tests are working as expected.
So what i've got is the following...
@RunWith(Cucumber.class)
@CucumberOptions(plugin = {"json:target/cucumber.json", "pretty"}, features = "src/test/features")
public class CucumberTest {
}
@ContextConfiguration
@SpringBootTest
public abstract class StepDefs {
}
public class MyStepDefs extends StepDefs {
@Inject
Service service;
@Inject
Repository repository;
[...]
}
I hope this helps you further
This is my configuration, you can try it
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
@ContextConfiguration(classes = {Application.class})
I've got it working in Spring Boot 1.5. I want to share the configuration with you:
