Github Actions integration

[mabdi]

Hi there,

I would like to integrate Mutalk into Github actions, so all projects can easily benefit from mutation testing by simply adding a workflow file.

I create this thread to share the progress, and also attract possible collaborations.

Status: Under developement

The main features are:

• It can be triggered manually or event-based (like on every pushes)
• It calculates the mutants on different modes:
  • Full: Runs Mutalk on all the project
  • Diff: Runs Mutalk only on the pushed code
  • Commit: You can specify a commit-id. The diff will be calculated from this commit.
• The mutation testing runs only if the build is successful based on SmalltalkCI.
• It runs mutation testing in two steps:
  • Extreme transformations: Extreme transformations are high-level mutants that strip methods body.
  • mutation testing We run mutation testing on the undetected extreme transformations.
• It will generate reports (in JSON and markdown formats) as artifacts.

A GitHub bot as a future step:

We can use a Github bot to show the result to developers and get feedback from them. If they decide to fix the uncovered part, the Bot can update a GitHub issue to remind them.
