I have a Spring Boot 2.7.1 (but same happens with 2.6.4) project using Cucumber BOM 7.4.1.
testImplementation(platform("io.cucumber:cucumber-bom:7.4.1"))
testImplementation group: 'io.cucumber', name: 'cucumber-java8'
testImplementation group: 'io.cucumber', name: 'cucumber-spring'
testImplementation group: 'io.cucumber', name: 'cucumber-junit-platform-engine'
My entry point is :
@Suite
@IncludeEngines("cucumber")
@SelectClasspathResource("features")
@ConfigurationParameters({
@ConfigurationParameter(key = GLUE_PROPERTY_NAME, value = "my.project.cucumber"),
@ConfigurationParameter(key = FILTER_TAGS_PROPERTY_NAME, value = "@Dwh"),
@ConfigurationParameter(key = JUNIT_PLATFORM_NAMING_STRATEGY_PROPERTY_NAME, value = "long"),
@ConfigurationParameter(key = PLUGIN_PUBLISH_QUIET_PROPERTY_NAME, value = "true"),
@ConfigurationParameter(key = PLUGIN_PROPERTY_NAME, value = "json:build/cucumber/cucumber.json")
})
public class RunCucumberDwhTest {
}
My glue code :
@SpringBootTest(classes = DwhE2EApplication.class, webEnvironment = RANDOM_PORT)
@ContextConfiguration(classes = DwhE2EApplication.class)
@CucumberContextConfiguration
@ActiveProfiles("test")
public class DwhStepDef implements En {
....
}
When running the Cucumber tests, I get this error :

io.cucumber.spring.TestContextAdaptor.notifyTestContextManagerAboutAfterTestMethod(TestContextAdaptor.java:125) ... 89 more
I can see in the logs that my Spring Context gets loaded, the in-memory DB gets bootstrapped... it fails after.
In debug mode, I see that the Given/When/Then steps are captured, so my feature file is found for sure.
Actually, it seems to fail when Cucumber performs some cleanup after a step executes :
at some point in io.cucumber.spring.TestContextAdaptor , we have this method that gets called :
private void notifyTestContextManagerAboutAfterTestMethod() {
try {
Object delegateTestInstance = delegate.getTestContext().getTestInstance();
Method dummyMethod = TestContextAdaptor.class.getMethod("cucumberDoesNotHaveASingleTestMethod");
delegate.afterTestMethod(delegateTestInstance, dummyMethod, null);
} catch (Exception e) {
throw new CucumberBackendException(e.getMessage(), e);
}
}
it's the delegate.getTestContext().getTestInstance() that throws the exception, as the testInstance is null.
any idea why this happens ?
