Is this really needed? Again, standardize on _one_ way to indicate expected
failures and stick to it, do not invent multiple ways.

Again, I'm not sure how this is redundant. What should I use instead?

Either subclass and set testShouldFail to true or just put this.testShouldFail =
true; as the first statement in the test.

Then you can remove changes to this generator script.

Putting this.testShouldFail = true as the first statement in the test doesn't
work, since this looks at the prototype of the fixture and not the fixture
itself. I have subclassed each fixture to make a version with testShouldFail =
true.

   var testPredicate = testShouldFail ? 'ASSERT_FALSE' : 'ASSERT_TRUE';
   var extraLibraries = genIncludes.concat(
       this[testFixture].prototype.extraLibraries.map(
