@Nested (Junit5) associated with @QuarkusTest causes an UnsatisfiedResolutionException

Description An UnsatisfiedResolutionException will be thrown when a test class is annotated with @QuarkusTest and implements inner test classes in connection with @Nested (Junit5).

Actual behavior The relevant dump of the stack trace (via mvn clean verify):

...
org.junit.jupiter.api.extension.TestInstantiationException: Failed to create test instance
Caused by: java.lang.RuntimeException: java.lang.reflect.InvocationTargetException
Caused by: java.lang.reflect.InvocationTargetException
Caused by: javax.enterprise.inject.UnsatisfiedResolutionException: No bean found for required type [class org.acme.testcoverage.GreetingResourceTest$NestedTestClass] and qualifiers [[]]
...

Steps to reproduce the behavior

1. Checkout https://github.com/quarkusio/quarkus-quickstarts/tree/master/tests-with-coverage-quickstart
2. Adjust https://github.com/quarkusio/quarkus-quickstarts/blob/master/tests-with-coverage-quickstart/src/test/java/org/acme/testcoverage/GreetingResourceTest.java

package org.acme.testcoverage;

import static io.restassured.RestAssured.given;
import static org.hamcrest.CoreMatchers.is;

import java.util.UUID;

import org.junit.jupiter.api.Nested;
import org.junit.jupiter.api.Tag;
import org.junit.jupiter.api.Test;

import io.quarkus.test.junit.QuarkusTest;

@QuarkusTest
@Tag("integration")
public class GreetingResourceTest {

    @Nested
    class NestedTestClass {
        @Test
        public void testHelloEndpoint() {
            given()
                    .when().get("/hello")
                    .then()
                    .statusCode(200)
                    .body(is("hello"));
        }
    }

    @Test
    public void testGreetingEndpoint() {
        String uuid = UUID.randomUUID().toString();
        given()
                .pathParam("name", uuid)
                .when().get("/hello/greeting/{name}")
                .then()
                .statusCode(200)

}

1. Execute mvn clean verify

Hi @stuartwdouglas ,

The issue still happen if the test class has multiple nested “Nested” classes. I’m using quarkus version 1.11.0-final

@QuarkusTest
@Tag("integration")
public class GreetingResourceTest {

    @Nested
    class NestedTestClass {

         @Nested
         class NestedDeeperTestClass {
         }
    }
}

@sebitit Unfortunately, @Nested is (still) not supported. See #4393 for more details.

@stuartwdouglas In #4409 an explicit and descriptive exception was introduced for this case, but it was removed by the big classloader change: https://github.com/quarkusio/quarkus/commit/b67491c1ffe76248d5f01bc3e29be94c2cdd56a4#diff-985ca913dc620dcf2e54fd5e2b62a2bfL417 Do you remember why? Seems we should bringt it back…
