Is it possible to mix jqwik with mockito tests?

Question

I'm working in a project which contains tests in mockito. I need to add more tests to this file, so I added a simple jqwik test, but if I try to run all tests all mockito ones are ignored.

"How can I use jqwik with Mockito?" is a common question. Here's a discussion of possible solutions. The most simple one:

class HelloTest {
    @Mock private Logger logger;
    @InjectMocks private MySubjectUnderTest sut;

    private AutoCloseable mockitoCloseable;

    @BeforeProperty //@BeforeTry
    void initMocks() {
        mockitoCloseable = MockitoAnnotations.openMocks(this);
    }

    @AfterProperty //@AfterTry
    void closeMocks() throws Exception {
        mockitoCloseable.close();
    }

    @Property
    void testWithRandomData(@ForAll final String data) {
        sut.doSomething();
        // Verify whatever should happen to logger instance
        // during doSomething() call, e.g.:
        Mockito.verify(logger).log(Level.WARNING, "my message");
    }
}

You go with @Before/AfterProperty or with @Before/AfterTry depending on whether your mocks should be reset for each try or for each property.
