Contributors

If you want to contribute to Lumibot, you can check how to get started below. We are always looking for contributors to help us out!

Steps to contribute:

1. Clone the repository to your local machine
2. Create a new branch for your feature
3. Run pip install -r requirements_dev.txt to install the developer dependencies
4. Install all the requriements from setup.py: pip install -e .
5. Make your changes
6. Run pytest to make sure all the tests pass
7. Create a pull request to merge your branch into master

Running Tests

We use pytest for our testing framework. To run the tests, you can run the following command:

pytest

Showing Code Coverage

To show code coverage, you can run the following command:

coverage run; coverage report; coverage html

Adding an Alias on Linux or MacOS

This will show you the code coverage in the terminal and also create a folder called "htmlcov" which will have a file called "index.html". You can open this file in your browser to see the code coverage in a more readable format.

If you don't want to keep typing out the command, you can add it as an alias in bash. To do this, you can run the following command:

alias cover='coverage run; coverage report; coverage html'

This will now allow you to run the command by just typing "cover" in the terminal.

cover

If you want to also add it to your .bashrc file. You can do this by running the following command:

echo "alias cover='coverage run; coverage report; coverage html'" >> ~/.bashrc

Adding an Alias on Windows

If you are on Windows, you can add an alias by running the following command:

Add to your PowerShell Profile: (profile.ps1)

function cover { 
 coverage run
 coverage report
 coverage html
}

Setting Up PyTest in VS Code

To set up in VS Code for debugging, you can add the following to your launch.json file under "configurations". This will allow you to go into "Run and Debug" and run the tests from there, with breakpoints and everything.

NOTE: You may need to change args to the path of your tests folder.

{
    "name": "Python: Pytest",
    "type": "python",
    "request": "launch",
    "module": "pytest",
    "args": [
        "lumibot/tests"
    ],
    "console": "integratedTerminal",
}

Here's an example of an actual launch.json file:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Pytest",
            "type": "python",
            "request": "launch",
            "module": "pytest",
            "args": [
                "lumibot/tests"
            ],
            "console": "integratedTerminal",
        }
    ]
}
