How can an AWS CodeBuild job see which files have changed?

I'm trying to set up an AWS CodeBuild project to run tests to validate PRs and commits on a GitHub repository.

Because of the nature of the repo (a monorepo combining several ML models):

  • I need to restrict down to only run tests associated with files changed in the PR/commit to keep time+cost under control, but
  • The tests will typically require reference to other un-changed files in the repo: So can't just only pull changed files through to the build container.

How can a running CodeBuild build triggered by a GitHub PR (as per the docs here) 'see' which files are changed by the PR to selectively execute tests?

In your buildspec file you can perform shell commands, I think you can use some git commands there and echo the result, so you can see them as logs during the build.
