@TestFactory does not work with QuarkusUnitTest

[masecla22]

Describe the bug

When a JUnit TestFactory includes an @Inject mock service bean initialisation works properly for normal @BeforeEach and @Test annotated methods, but tests executed with @TestFactory have the mock service uninitialised.

Expected behavior

The @Inject bean is initialized correctly during @TestFactory execution.

Actual behavior

The @Inject mock bean fails to be initialized and is thus null.

How to Reproduce?

public class SimpleBeanTestFactoryTest {
    @RegisterExtension
    static final QuarkusUnitTest config = new QuarkusUnitTest()
            .withApplicationRoot((jar) -> jar
                    .addClasses(SimpleBean.class)
                    .addAsResource(new StringAsset("simpleBean.baz=1"), "application.properties"));

    @Inject
    SimpleBean simpleBean;

    @TestFactory
    public List<DynamicTest> testBeanInsideFactory() {
        return List.of(
                DynamicTest.dynamicTest("test 1", () -> {
                    assertNotNull(simpleBean);
                }),
                DynamicTest.dynamicTest("test 2", () -> {
                    assertEquals(1, 1);
                }));
    }
}

Additional information

A similar issue happened in #8004, and was fixed in #8066. I have ported the fix, I can confirm it works, and will be making a PR shortly.

Thanks for reporting.

QuarkusUnitTest is meant for internal testing of extensions themselves and as we have never had the need to use @TestFactory, we are very unlikely to make this happen.
If someone however wants to work it, the contribution will be very welcome.
