Having two RouterTest classes in the same module is confusing

Problem/Motivation

Our naming conventions for OO code state:

Test classes only need to be unambiguous within the context of the module they are testing.

However, we have both of:
Drupal\system\Tests\Routing\RouterTest
and
Drupal\system\Tests\Menu\RouterTest

This wasted hours upon hours of my time because I somehow repeatedly misread the namespace.

Proposed resolution

Even though both classes technically are acceptable given our coding standards, the fact that they both belong to the same module is very confusing, and it can't hurt to give one or both classes more specific names.
