Twister DeviceHandler now checks `--enable-coverage` command line argument instead of `--coverage` when it deals with device output. This resolves potential problem when only `--enable-coverage` argument is given and the coverage report is not needed. In this case the test image which is built for code coverage works slower also producing additional console output, so the additional DeviceHandler timeout still have to be applied and the output with coverage data correctly processed by Harness.

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.
