"""
Run new or changed tests in repeated mode to validate their stability.
Running burn_in_tests_multiversion will run new or changed tests against the appropriate generated multiversion
suites. The purpose of these tests are to signal bugs in the generated multiversion suites as these tasks are
excluded from the required build variants and are only run in certain daily build variants. As such, we only expect
the burn-in multiversion tests to be run once for each binary version configuration, and `--repeat-*` arguments
should be None when executing this script.
There are two modes that burn_in_tests_multiversion can run in:
(1) Normal mode: by default burn_in_tests will attempt to run all detected tests the
configured number of times. This is useful if you have a test or tests you would like to
check before submitting a patch to evergreen.
(2) By specifying the `--generate-tasks-file`, burn_in_tests will run generate a configuration
file that can then be sent to the Evergreen 'generate.tasks' command to create evergreen tasks
to do all the test executions. This is the mode used to run tests in patch builds.
NOTE: There is currently a limit of the number of tasks burn_in_tests will attempt to generate
in evergreen. The limit is 1000. If you change enough tests that more than 1000 tasks would
be generated, burn_in_test will fail. This is to avoid generating more tasks than evergreen
can handle.
