Create the `fail` method

[jazcarate]

context (example) {
    describe("Failure") {
        it("shouldFail") {
            fail("That's the test");
        } end
}

I don't have a better use case :smile_cat:

I think you need to use skip in this cases instead of make a test that fails. A failing test is useless unless it was created by a template or wizard.
