Validation

CAM repository provides infrastructure for running unit tests and integration tests.

Unit Tests

C based CAM components

CAM repository uses CTest for running unit tests on C based CAM components cam-service, cam-uuid and libcam. Each CAM component has a test directory that hosts the unit test related files, for example cam-service/test hosts files needed to run unit tests cam-service. Refer to CTest for more information on developing and running CTest.

Before running the CTest, make sure to follow the steps listed in the Build section.

Run CTest:

cd ~/cam/build
ctest -V

The output on the terminal should look like below, directory name might vary:

Python based CAM component

CAM project uses Pytest for the python-based cam-tool component. Refer to cam-tool/test for more information on the unit test for cam-tool. Refer to pytest for more information on developing and running Pytest.

Before running the Pytest, make sure to follow the steps listed in the Build section. It is also required to follow the steps listed in Setup terminal environment in the terminal where pytest will be run.

Run Pytest:

cd ~/cam/critical-app-monitoring
pytest cam-tool/test --junitxml=./cam-tool-report.xml

The output on the terminal should look like below, directory name might vary:

Integration Tests

CAM project uses Pytest for running integration tests on CAM components. The integration tests consist of a series of tests that can be found in test. Integration tests are broadly classified into:

Calibration Tests: Various tests where cam-app-example runs in calibration mode to generate CSEL files and cam-tool performs analysis on the generated CSEL files.
Configuration Deploy Tests: Various tests to test analysis and deployment of event streams by cam-tool and the effect on cam-service.
Static Configuration Tests: Various tests where cam-app-example starts with different configurations and checks the behavior of cam-service.

Before running the Pytest, make sure to follow the steps listed in the Build section. It is also required to follow the steps listed in Setup terminal environment in the terminal where pytest will be run.

Run integration tests:

cd ~/cam/critical-app-monitoring
pytest --basetemp=./logs --install-dir=~/cam/cam-packages/ --junitxml=./cam-tests-report.xml ./test/

The output on the terminal should look like below, directory name might vary:
