如何在Junit5中使用Serenity？

Question

I'm trying to run Serenity Tests in my maven project. I'm using junit-jupiter-engine 5.3.1. (It's in the parent pom.)

I'm getting multiple error.

Is it because the JUnit's version or is there something else? How can I solve it?

My test class:

@RunWith(SerenityRunner.class)
public class MyTestClass {

private static final String CHARACTER_ENCODING_UTF_8 = "UTF-8";

@Steps
private ApiSteps apiSteps;


@Test
public void aTest() {

    try {
        String filePath = "initiatepayment/input.xml";

        Client client = Client.create();

        WebResource webResource = client
                .resource("https://jsonplaceholder.typicode.com/posts/42");

//            String input = new Scanner(MyTestClass.class.getClassLoader().getResourceAsStream(filePath), CHARACTER_ENCODING_UTF_8).useDelimiter("\\A").next();
        String input = "{\"address\": \"Budapest\"}";

        ClientResponse response = webResource.type("application/json")
                .get(ClientResponse.class);


        System.out.println(response.getStatus());

        System.out.println("Output from Server .... \n");
        String output = response.getEntity(String.class);
        System.out.println(output);

    } catch (Exception e) {

        e.printStackTrace();

    }
}

@Test
public void bTest() {
    apiSteps.sendGetRequest("https://jsonplaceholder.typicode.com/posts/42", WebResourceType.APPLICATION_XML);
    apiSteps.checkStatus(200);
}
}

My ApiSteps class (It extends BaseSteps class which is empty, but that extends the net.thucydides.core.steps.ScenarioSteps class):

public class ApiSteps extends BaseSteps {

private static final String CHARACTER_ENCODING_UTF_8 = "UTF-8";
private static String message;
private static ClientResponse clientResponse;

@Step
public void getMessageByPath(String filePath) {
    message = new Scanner(ApiSteps.class.getClassLoader().getResourceAsStream(filePath), CHARACTER_ENCODING_UTF_8).useDelimiter("\\A").next();
}

@Step
public void sendGetRequest(String url, WebResourceType type) {
    Client client = Client.create();
    WebResource webResource = client.resource(url);
    clientResponse = webResource.type(type.getValue()).get(ClientResponse.class);
}

@Step
public void sendPostRequest(String url, WebResourceType type) {
    Client client = Client.create();
    WebResource webResource = client.resource(url);
    clientResponse = webResource.type(type.getValue()).post(ClientResponse.class, message);
}

@Step
public void checkStatus(int expectedStatusCode) {
    Assert.assertEquals(clientResponse.getStatus(), expectedStatusCode);
}

}

And my stack trace:

Thank you!

Unfortunately Serenity is not supported by basic JUnit 5 so I had to use JUnit 5 Vintage only. It can run JUnit 4 tests. It works now.
