Extend Twister Harness 'recording' feature to allow multiple regular expression patterns to extract different types of records from test output. Add 'merge' recording mode to collect all extracted data fields into a single record object of the test instance. Export to CSV file now takes all field names occurred in the collected records, sort it alphabetically, and then use it for columns instead of using only the first record's fields. This is done to address possible situation when records have different set of fields. Adjust Twister documentation and test suite to the above changes.

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.
