Why my Jenkins JUnit test no longer works?

A bit of context.

I'm developing an extensión for Jenkins, that consists of a new WEB API aimed to provide our ALM tooling with customized endpoints and features. The starting point for me was this guide, which I have reproduced step by step.

After some manual tests of a bare minimum API, I concluded that the extension was ready for further development. However, I wanted to make the test automatic during the build phase, so I implemented a canary test following the previous guide and this other to feed test with @LocalData.

The firsts times I run the JUnit, everything went as expected. Test passed. I was able to run mvn clean packge and complete the tests.

Today, I did open the IDE, run the same maven goals to ensure that everything was ok, but all my test failed due to an 404 Not Found

Does anyone know why my test' no longer finds my API? It looks like the plugin was not loaded. If I run mvn hpi:run, the plugin creates work in my project's root dir and I can see the plugin installed in work/plugins/. So, I tested again, this time manually, if the API that caused the previous 404 was accessible and it was.

It should be something related to my local environment or workspace, but I don't know what could have changed since the last time tests worked.

This is the source code of the test

@Rule
public JenkinsRule jenkinsRule = new JenkinsRule();

public void test_ping() throws Exception {

   JenkinsRule.WebClient webClient = jenkinsRule.createWebClient();
   JenkinsRule.JSONWebResponse response = webClient.getJSON("alm-api/ping");
   logJenkinsWebResponse(response);
        
   assertThat(response.getStatusCode(), is(200));
   assertThat(response.getJSONObject().get("pong"), notNullValue());
    
}
private static void logJenkinsWebResponse(JenkinsRule.JSONWebResponse response) {
   try {
    LOG.info(response.getJSONObject().toString(2,2));
   }catch(JSONException ex) {
    LOG.info(response.getContentAsString());
   }
}

And this's the production code

@Extension
public class AlmApi implements RootAction {

    protected static final String ALM_API_NAME = "alm-api";

    @Override
    public String getIconFileName() {
        return null;
    }

    @Override
    public String getDisplayName() {
        return null;
    }

    @Override
    public String getUrlName() {
        return ALM_API_NAME;
    }

    @GET
    @WebMethod(name = "ping")
    public JsonHttpResponse ping() {
        JSONObject response = JSONObject.fromObject(new PongDTO(Instant.now()));
        return new JsonHttpResponse(response, 200);
    }
}

_{PongDTO: Plain old java object}

Observations: I have realised that Jenkins Test, creates target/jenkins-for-test but everything I see in there is a very small version of Jenkins but I don't find any plugin/ folder. I guess, during the test phase, my extensions get injected into the classloader on-the-fly.

My code is being committed in a GitLab repository every time something in the source code changes. So, I have checked out previous commits (proven to work and pass tests) and tried to run tests again. No test passed. The problem has been the same: 404 Not Found.

I have also tried ending endpoints with a trailing slash (/) in all the calls from JUnit tests. It didn't work either.
