Describe the issue
The directory "src/coreComponents/unitTests" contains test that are not unit tests.

Proposed cleanup

1. rename directory to "src/coreComponents/unitTests" to "src/coreComponents/integrationTests"
2. move any actual unit tests in "src/coreComponents/integrationTests" to their appropriate component unitTests directory.
3. rename "integratedTests" to "applicationTests"
