Nile plugin adding coverage reports for Cairo Smart Contracts.

nile-coverage

Nile plugin adding coverage reports for Cairo Smart Contracts.

Getting started

Install the plugin inside the virtual environment of your Nile project:

(env): pip install nile-coverage

Nile automatically detects installed plugins using python entry points feature. You should see the coverage command listed running nile, and you can run the report with:

(env): nile coverage

For a full list of options run:

(env): nile coverage --help

Recipes

1. Run coverage in a subset of the tests suite.

Mark tests with pytest marks and use the --mark argument to run a subset of tests:

(env): nile coverage -m unit

2. Integrate with codecov.io.

Generate a cobertura format coverage xml file named "coverage.xml" using the --xml flag:

(env): nile coverage --xml

3. Change the default folder containing Smart Contracts.

If your Smart Contracts are in a different folder than "contracts" (Nile default), use the --contracts-folder flag to set the correct one:

(env): nile coverage -c src

This package uses the starknet-edu/cairo-coverage Virtual Machine override to get covered lines for the final report. Special thanks to @LucasLvy from StarkWare!
