@AayushSabharwal I'm trying to learn here. How does the number of tests passed go from 539 to 572?

When there's an error outside of a test, the rest of the testset is skipped. So the tests after the error don't run and aren't counted in the total. When the error is fixed, the rest of the tests now run and are counted in the total.
