Improve DUT selection at DeviceHandler: for each DUT it counts how many test instances have been failed on it during the current twister execution, so the next available DUT will be chosen ordering the eligible DUTs by less failures occured so far. The new selection mechanism should increase chances to retry failed tests on different DUTs, for instance to resolve ploblems when some DUTs have connectivity or HW issues slowing down test plan execution, or even block the execution when only one test suite runs whereas the same first DUT candidate in the list is not working and others were not chosen.

Twister Testing
Running the tests require the environment variable ZEPHYR_BASE to be set.
Twister Testsuite are located in $ZEPHYR_BASE/scripts/tests directory with all the data files in $ZEPHYR_BASE/scripts/test_data directory.
Dependencies
Install all the dependencies using
pip install -r $ZEPHYR_BASE/scripts/requirements-build-test.txt
Executing testsuite
The testcases can be executed from the root directory using
pytest $ZEPHYR_BASE/scripts/tests/twister
Twister Coverage
The coverage for all the tests can be run using the command below. This will collect all the tests available.
coverage run -m pytest $ZEPHYR_BASE/scripts/tests/twister/
Then we can generate the coverage report for just twister script using
coverage report -m $ZEPHYR_BASE/scripts/pylib/twister/
To generate the coverage report for twister script use below command
coverage report -m $ZEPHYR_BASE/scripts/twister
The html coverage report for twister can be generated using
coverage html twister
If needed,the full coverage html report can be generated in every run of "pytest" in the tests directory using configuration file (setup.cfg).
Organization of tests
- conftest.py: Contains common fixtures for use in testing the twister tool.
- test_twister.py : Contains basic testcases for environment variables, verifying testcase & platform schema's.
- test_testsuite_class.py : Contains testcases for Testsuite class (except reporting functionality) in twisterlib.py.
- test_testinstance.py : Contains testcases for Testinstance and Testcase class.
- test_reporting_testsuite.py : Contains testcases for reporting functionality of Testsuite class of twister.
