Hi,

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

After manual tests of a bare minimum API, I concluded that the extension was working and ready for further development.

To speed up development and testing, I have also prepared a canary test in JUnit, following the previous guide (linked above) and this other to feed test with @LocalData.

The firsts times I run the JUnit, it worked. Test passed. So, I was able to run mvn clean packge and complete the build executing (and passing) all tests

Today, I did open the IDE, run the same maven goals to ensure that everything was ok (a routine of mine), but tests failed due to a 404 Not Found

Here the stacktrace

Test timeout disabled.

When I run mvn hpi:run to do manual testing, the extension works and the endpoints are accessible. I also check that work/plugins contain my extension packaged as hpi.

I have realised that when I run JenkinsRule , a new Jenkins is downloaded and deployed in /tmp and static content is deployed in {projectDir}/target/jenkins-for-test. But my plugin is not in any of these folders. So my guess is that the failure is caused because my source code is not loaded properly during the test execution.

Does anyone know why my JUnit' no longer load and finds my extension?

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.

The test code is

@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());

}

No JUnit @RunWith specified

The production code of the API is

@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);

}

Thank you in advance!
