Using Java 8 lambdas as tested classes

[VsevolodGolovanov]

I'm currently using parameterized tests with anonymous inner classes:

@RunWith(Parameterized.class)
public class RulesTest extends AbstractDetectorTest<MyDetector> {

    enum Expectation {
        FAIL, PASS
    };

    private Expectation expectation;
    private Object parameter;

    public RulesTest(int ln, Expectation expectation, Object parameter) {
        this.expectation = expectation;
        this.parameter = parameter;
    }

    // use source line number in test's name to quickly find the failing dataset
    @Parameters(name = "Line {0}")
    @SuppressWarnings({ "unused" })
    public static Collection<Object[]> data() {
        return Arrays.asList(new Object[][] {
            //@formatter:off
            { ln(), PASS, new Object() { void $() { someCodeToCheck(); } } },
            { ln(), PASS, new Object() { void $() { moreCodeToCheck(); } } },
            // ... more parameter sets ...
            //@formatter:on
        });
    }

    @Test
    public void test() throws Exception {
        switch (expectation) {
        case FAIL:
            DetectorAssert.assertBugReported(parameter.getClass(), detector, bugReporter);
            break;
        case PASS:
            DetectorAssert.assertNoBugsReported(parameter.getClass(), detector, bugReporter);
            break;
        default:
            checkState(false);
        }
    }

}

I want to get rid on the verbose new Object() { void $() { } stuff. Let's try using lambdas for this:

interface $ {
    public void method();
}

...
    { ln(), PASS, ($)() -> someCodeToCheck() },

This fails when running the test:

Is it possible to support lambdas for such usage?
