-**$CIMEROOT/scripts/lib/CIME/tests/scripts_regression_tests.py** is the suite of internal tests we run
-for the stand-alone CIME testing. With no arguments, it will run the full suite. You can limit testing to a specific
-test class or even a specific test within a test class.
-
-**CCSM_CPRNC should be defined in config_machines.xml for your system prior to running scripts_regression_tests.py**
-
-Run full suite::
-
-  python scripts/lib/CIME/tests/scripts_regression_tests.py
-
-Run a test class::
-
-  python scripts/lib/CIME/tests/scripts_regression_tests.py CIME.tests.test_unit_case
-
-Run a specific test::
-
-  python scripts/lib/CIME/tests/scripts_regression_tests.py CIME.tests.test_unit_case.TestCaseSubmit.test_check_case
-
-If a test fails, the unittest module that drives scripts_regression_tests wil note the failure, but
-won't print the output of the test until testing has completed. When there are failures for a
-test, the case directories for that test will not be cleaned up so that the user can do a post-mortem
-analysis. The user will be notified of the specific directories that will be left for them to
-examine.
-
-The test suite can also be ran with `pytest` and `pytest-cov`. After the test suite is done running
-a coverage report will be presented.
-
-Install dependencies::
-
-  python -m pip install pytest pytest-cov
-
-Run full suite::
-
-  pytest -vvv
-
-Run just unit tests::
-
-  pytest -vvv scripts/lib/CIME/tests/test_unit*
-
-Run a test class::
-
-  pytest -vvv scripts/lib/CIME/tests/test_unit_case.py
-
-Run a specific test::
-
-  pytest -vvv scripts/lib/CIME/tests/test_unit_case.py::TestCaseSubmit::test_check_case
