On the top level you can find different languages that are supported.
On the second level (in a particular language's directory) you'll find different testing frameworks that are supported.
In each directory for a particular framework, there is always README.md file
that contains various useful information. At minimum it contains the
information on how to install the dependencies and run the tests.
You are welcome to contribute by submitting likewise a min setup for your language or framework of choice with a pull request. If possible please also create a github workflow.
Cookiecutter has a similar goal and also supports multiple languages for setting up a bare project.
