mozregression is an interactive regression rangefinder for quickly tracking down the source of bugs in Mozilla nightly and integration builds.
You can start using mozregression today:

To make setup more deterministic, we have provided requirements files to use a known-working set of python dependencies. From your mozregression checkout, you can install these inside a virtual development environment.
After checking out the mozregression repository from GitHub, this is a two step process:
Be sure you are using Python 3.8 or above: earlier versions are not supported (if you
are not sure, run python --version or python3 --version on the command line).
From inside your mozregression checkout, create a virtual environment, activate it, and install the dependencies. The instructions are slightly different depending on whether you are using Windows or Linux/MacOS.
On Windows:
python3 -m venv venv
venv\Scripts\activate
pip install -r requirements\requirements-3.9-Windows.txt
pip install -e .
On Linux:
python3 -m venv venv
source venv/bin/activate
pip install -r requirements/requirements-3.9-Linux.txt
pip install -e .
On macOS:
python3 -m venv venv
source venv/bin/activate
pip install -r requirements/requirements-3.9-macOS.txt
pip install -e .
NOTE: You should replace the Python version with the one that matches with the virtual environment.
After running the above commands, you should be able to run the command-line version of
mozregression as normal (e.g. mozregression --help) inside the virtual environment. If
you wish to try running the GUI, use the provided helper script:
python gui/build.py run
To run the unit tests for the console version:
pytest tests
For the GUI version:
python gui/build.py test
Before submitting a pull request, please lint your code for errors and formatting (we use black, flake8 and isort)
./bin/lint-check.sh
If it turns up errors, try using the lint-fix.sh script to fix any errors which can be addressed automatically:
./bin/lint-fix.sh
Create a new GitHub release and give it a tag name identical to the version number you want (e.g. 4.0.20). CI should automatically upload new versions of the GUI applications to the release and to TestPyPI and PyPI.
Follow the following conventions for pre-releases:
For more info, see PEP 440.
Uploading the signed artifacts is a manual process at this time. To sign and notarize a macOS release, follow these steps:
signing-manifests/mozregression-macOS.yml in the adhoc-signing repo with those changes.mozregression-gui-app-bundle.tar.gz and extract it in gui/dist../bin/dmgbuild.FAQs
