Usage

The Iris project is meant to be used with your own "target" and tests. A target is basically a pytest plugin invoked by Iris, which will then gather data during the run to present in a web-based interface known as the Iris Control Center.

Iris is available as a PyPI library named moziris. It requires system dependencies that are installed using the bootstrap script from this repo.

Once your system is configured, and the setup instructions have been followed, you can test some of Iris' functionality.

To invoke the "sample" target - which is just a placeholder project for demonstration purposes:

iris sample

To open the Control Center, which is the web-based UI for managing local Iris runs:

iris -k

To verify that the Iris API itself exists, without running tests, this command will move your mouse on screen:

api-test

A complete list of command-line options is available when invoking the -h flag.

For more detailed examples, see the project wiki.

Enable Pre-Commit Hooks

Iris has pre-commit hooks for flake8 linting and black code formatting. These hooks will run black and flake8 prior to committing your changes.

This means that black will format all python files in-place, and flake8 will lint your code for any errors. If there are flake8 violations, your changes will not be committed. The list of ignored rules is documented in the tox.ini file. There should be a compelling reason to do so before adding to this list.

If you already have Iris installed on your system prior to this patch, you will need to run pipenv install again to install the pre-commit module.

# Install dependencies, including pre-commit
pipenv install
# Install pre-commit hooks defined in .pre-commit-config.yaml
pre-commit install

That's it! Here's an example of how it works:

# make some changes
git add -A
git commit -m 'detailed commit message'
