More details in build.sbt and updated dependencies

While updating the dependencies, I noticed that v3.2 of scalatest is very different from v3.1 (https://www.scalatest.org/release_notes/3.2.0). Therefore, I also needed to update the test files.
But, there is a "too many arguments" error that needs to be solved (I do not know why it was working before).
