I'm a professor in the humanities so I can write tests that make it harder to cheat than some other fields. I cringe whenever I hear someone using these invasive kinds of software. There has to be a better way than making students install spyware.
As a result, most tests consists of multiple-choice questions and standard-format open questions. It is unclear to what extent they test students' understanding, and students do become quite proficient test takers, but at least theses tests can be executed given the current constraints of available staff, acceptable rigor, and student expectations.
Unfortunately, you cannot move these type of test to an online setting and expect students not to cheat at all. It is too easy to talk to classmates, look at the study materials, or even on the Internet for some hints to answers or even the actual answers. The only option many institutions saw was to move to a draconian proctoring solution because they just lack the means to roll-out anything else given the constraints they have to work with.
Ideally, they would re-evaluate their choices regarding quality versus quantity, but because they need the large number of students to stay afloat, nothing meaningful will happen.
