• 1. cd E3SM/cime/scripts
  2. ./create_test test_suite [--compiler compiler --baseline-root e3sm_baseline_dir -t test_id -r test_root_dir] [-(c|g) [-b baseline_name ]] [--project project_or_account ]
     
     1. machine - The E3SM scripts will probe your machine name from the current nodename
     2. compiler - The compiler toolset you wish to use, examples are: gnu, intel, pgi. You do not need to provide this if you want the default compiler (the first compiler listed in the COMPILERS parameter for your machine)
     3. test_suite - The name of the test category you want to run, like e3sm_developer. You can also provide a list of test names.  Instead a test suite, you can specify one specific test or set of tests.
     4. test_root_dir - The path where your test cases will be dumped. Default will be CIME_OUTPUT_ROOT for the machine you are using.
     5. e3sm_baseline_dir - You only need to specify this if you want to use a different baseline area than is specified for your machine by the BASELINE_ROOT parameter
     6. -c /-g - Do a baseline comparison/generation. You do not have to do any baseline operationscompare against baselines you generated in Generating new baseline files for a topic branch or the system default baselines which are usually from latest master.
     7. If you generate new baselines, especially for shared master and next branches, make them group-writable by others:
        1. 1. chmod -R g+w $BASELINE_ROOT/$branch_name
     8. baseline_subdir - The name of the baselines (usually the major release you're on) you want to use. The default will be <current-branch-name>. Note that the tool will always prepend the compiler to the baseline subdir. Our baselines are always segregated by compiler. Don't bother with this option unless you provided -c or -g.
     9. project_or_account - The id that lets you run batch jobs on this machine
     10. test_id  - a string appended to end of test name.  default is a date and sha such as ".20210708_184630_c657sy"
     11. for a complete list of options, do "./create_test --help"
  3. Once the tests are running, you'll want to see test results
     1. Case 1: Simple
        
        1. cd test_root_dir
        2. you will find a script named cs.status.(testid) You can run this script from the test root directory to see the status of tests being run within this suite
     2. Case 2: We have a more sophisticated script called wait_for_tests that provides extra capabilites like: waiting for tests to finish, converting results to CTest and submitting to a CDash dashboard
        
        1. cd test_root_dir
        2. <E3SM>/cime/CIME/wait_for_tests [ -d buildname] */TestStatus
  4. Example 1  Testing without baselines: to run the 'e3sm_developer' suite on Chrysalis using the Intel compiler, you would run:
     1. (make sure the clone is checked out on your development branch)
     2. cd E3SM/cime/scripts
     3. ./create_test e3sm_developer -r mytestrun (the script will detect its on Chrysalis and use the default compiler, intel)
     4. cd /lcrc/group/e3sm/$USERID/scratch/chrys/mytestrun
     5. ./cs.status.(testid).
  5. Example 2:  Testing against baselines:
