Metamorphic relation examples implemented in gemtest.
To run all metamorphic relations from the 16 program domains
install Python dependencies with poetry:
poetry install
and run metamorphic test suites with:
poetry run pytest <options> <path to test file/folder>
We also prepare poetry commands for running some examples such as:
poetry run example simple/test_add.py
poetry run example trigonometry/test_sin.py
poetry run example house_pricing/test_house_pricing.py
poetry run example shortest_path/test_path.py
poetry run example facial_keypoints/test_keypoints.py
poetry run example gtsrb/metamorphic_tests
poetry run example linalg/test_solve.py
Currently supported: Python Versions 3.8 - 3.12
- Tested under Ubuntu 20.04 with poetry 1.4.0 and python 3.10.12
- Tested under Windows 11 running WSL2 with poetry 1.5.1 and python 3.10.6
- Tested under Windows 11 native with poetry 1.5.1 and python 3.10.6
