"Among the requirements for the major are successful performance on a junior qualifying examination, completion of a yearlong senior thesis based on original research or artistic expression, and a successful oral defense of the thesis before an interdisciplinary faculty board."
I was answering a question about grades, not tests.
Also "demonstrate rigor" absolutely does not imply tests. In my undergrad (math) the level of rigor of tests was uniformly (and necessarily) much lower than homework and other assignments without the same time pressure. I would expect the same to be true in many other fields.
Pass/fail is still a grade, albeit a binary one. Caltech had pass/fail for freshman, and still most everyone felt the pressure at the end of the semester with the final exam looming, and worked hard to pass it.
