use exact regex expressions for test names

[anniehedgpeth]

Background

TF-8610
Right now the tests use the contain function for the test names, which causes more tests to run than you desire. This will force the use to use the exact name but only the test they want to run will run. The downside is that you can't put notes in that comment because it will cause it to not match exactly, but the user can simply add a follow up comment instead.

How Has This Been Tested

Will be tested post-merge.
