Scala certainly doesn't remove the needs for tests. But it reduces it a lot. I would say that it reduces the required number of tests to something between 1% to 10%, depending on the domain. The more "calculations"/"math" the domain contains, the more tests are necessary. But for the "plumbing" which usually makes up for the biggest amount of code, it does wonders. Scala 3 is also quite different compared to the early times. Unfortunately the reputation is still a bit outdated.
