You've got people like Project Farm over on YT. He does really good, rigourous stuff. He did a test on wiper blades where tested them new, then left them on the roof of his house in the sun for a full year, and then did all the tests again. He also rarely states firm conclusions, just presents objective data. The only real exception is when one, or a few products standout as either exceptionally good (especially when they're NOT the most expensive) or they do so poorly as to be totally unfit for purpose or even unsafe.

The products he reviews tend to be sort of workshop oriented (tools - from basic open end wrenches up to fairly capable welders and chainsaws, lubricants, that kind of thing), but he's also done a fair bit of automotive stuff, jeans, gloves, and things like that.'

For the jeans, he tested stuff like puncture force (with a nail), abrasion resistance, belt loop strength, and breathability. He also commented on but did not score fit and comfort.
