This is now in progress

• share common test classes (Refactor out common test classes into new test project #2350)
• share common test resources
• ... and

We should share as many test resources as possible. This means

1. putting all test resources in a common location
2. rewriting our TestProject fixtures to access them
3. fix tests to address any deviation in test projects that have happened over time.
4. and so much more!!!
