Micronaut and Gradle can't get tests working

I'm new to Micronaut and Gradle and I'm having some issues trying to get a simple controller application setup. I can run the app but the tests do not work. I'm thinking it must be due to my gradle configuration.

All of my classes exist in the same package.

Here is my simple application test:

package com.company;

import io.micronaut.runtime.EmbeddedApplication;
import io.micronaut.test.extensions.junit5.annotation.MicronautTest;
import javax.inject.Inject;
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;

@MicronautTest(packages="com.company")
class ApplicationTest {

  @Inject EmbeddedApplication<?> application;

  @Test
  void testItWorks() {
    Assertions.assertTrue(application.isRunning());
  }
}

and my simple application:

package com.company;

import io.micronaut.runtime.Micronaut;

public class Application {
  public static void main(String[] args) {
    Micronaut.run(Application.class, args);
  }
}

I can run the application just fine. But when I try to use the tests I get the following error:

Failed to inject value for field [application] of class: com.company.ApplicationTest

Path Taken: ApplicationTest.application
io.micronaut.context.exceptions.DependencyInjectionException: Failed to inject value for field [application] of class: com.company.ApplicationTest

I have a similar error with my controller tests

package com.company.controller;

import io.micronaut.http.annotation.*;

@Controller("/")
public class TestController {

  @Get(produces = "text/plain")
  public String index() {
    return "Micronaut Webservice Example for Demo";
  }
}

My controller test class:

package com.company.controller;

import static org.junit.jupiter.api.Assertions.*;

import io.micronaut.http.HttpStatus;
import io.micronaut.http.client.RxHttpClient;
import io.micronaut.http.client.annotation.*;
import io.micronaut.test.extensions.junit5.annotation.MicronautTest;
import javax.inject.Inject;
import org.junit.jupiter.api.Test;

@MicronautTest
public class TestControllerTest {

    @Inject
    @Client("/")
    RxHttpClient client;

    @Test
    public void testIndex() {
        assertEquals(HttpStatus.OK, client.toBlocking().exchange("/helloController").status());
    }
}

Here is the error

Any help is appreciated

For the error "Invalid service reference [/] specified to @Client" I can provide following information:

I got this error, when building an io.micronaut.library instead of an io.micronaut.application. (You should also show the plugins on the relevant part of the Gradle configuration). My Micronaut application consists of sub-projects like app, core, api,... and only the app project is built as io.micronaut.application.

I think the error happens because on a library build there is now server runtime startet upon tests. But a runtime is needed for the integration tests with injected HttpClient.

Is that your case? then:

Solution for sub-projects

Move your integration tests to the sub-project with the io.micronaut.application plugin. I solved it that way.

Solution for library only

Create a simple io.micronaut.application (which includes the io.micronaut.library) and place your test there.

I had the same issue, solved it by adding this dependency:

implementation "io.micronaut:micronaut-http-server-netty"

side-note: I just ran into this problem (again), googled it and landed here - saw my previous comment on the original post made in June, followed my own advice - problem solved.
