I think that this could be compressed a bit as follows.

function FrameworkUnitTestFail() {
  this.__proto__ = FrameworkUnitTest.prototype;
  this.testShouldFail = true;
}

That is bad practice. The following would fail then:

var test = new FrameworkUnitTestFail;
assertTrue(test instanceof FrameworkUnitTestFail);

Ok, so this is a nop.  <not> Done.  :)
