"""Tool for running suites of tests and waiting for completion.
The desired test suite will be scheduled with autotest. By default,
this tool will block until the job is complete, printing a summary
at the end. Error conditions result in exceptions.
This is intended for use only with Chrome OS test suits that leverage the
dynamic suite infrastructure in server/cros/dynamic_suite.py.
This script exits with one of the following codes:
0 - OK: Suite finished successfully
1 - ERROR: Test(s) failed, or hits its own timeout
2 - WARNING: Test(s) raised a warning or passed on retry, none failed/timed out.
3 - INFRA_FAILURE: Infrastructure related issues, e.g.
* Lab is down
* Too many duts (defined as a constant) in repair failed status
* Suite job issues, like bug in dynamic suite,
user aborted the suite, lose a drone/all devservers/rpc server,
0 tests ran, etc.
* provision failed
TODO(fdeng): crbug.com/413918, reexamine treating all provision
failures as INFRA failures.
4 - SUITE_TIMEOUT: Suite timed out, some tests ran,
none failed by the time the suite job was aborted. This will cover,
but not limited to, the following cases:
* A devserver failure that manifests as a timeout
* No DUTs available midway through a suite
* Provision/Reset/Cleanup took longer time than expected for new image
* A regression in scheduler tick time.
5- BOARD_NOT_AVAILABLE: If there is no host for the requested board/pool.
6- INVALID_OPTIONS: If options are not valid.
