Pixi Build Testsuite

This repo contains the testsuite that is used by both Pixi CI and pixi-build-backends CI to verify that they work properly in combination.

Local development

The tests can use the pre-built binaries produced by the Pixi and pixi-build-backends CI workflows. Download the latest artifacts for your platform:

pixi run download-artifacts

The binaries are stored in artifacts/, alongside a download-metadata.json file that records which branch or PR each artifact originated from. When running locally the script will reuse the active gh auth session; if gh is unavailable, set GITHUB_TOKEN or pass --token. Use --repo pixi or --repo pixi-build-backends to fetch artifacts for a single project.

With the artifacts in place you can run the fast subset of the tests (or any other Pixi task):

pixi run test

Using local builds instead of artifacts

If you prefer to use local checkouts, create a .env file with the paths to your repositories:

PIXI_REPO="/path/to/pixi-repository"
PIXI_BIN_DIR="${PIXI_REPO}/target/pixi/release"

BUILD_BACKENDS_REPO="/path/to/pixi-build-backends-repository"

Then build the binaries with:

pixi run build-repos

Testing PR combinations

To test a combination of PRs from this testsuite with PRs from Pixi or pixi-build-backends:

1. Create a .env.ci or modify your local .env file with PR numbers:

   # Test with specific PR from pixi repository
   PIXI_PR_NUMBER="123"
   
   # Test with specific PR from pixi-build-backends repository
   BUILD_BACKENDS_PR_NUMBER="456"

2. pixi run download-artifacts (locally or in CI) will download artifacts from these PRs instead of main
3. Important: Remove .env.ci before merging to main (CI will prevent merge if present)

This allows you to test how your testsuite changes work with specific PRs from the other repositories.
