Changes:

  • added generate-tests.ts script in the treeshake-test directory, that iterates over exports from typegpu, typegpu/data and typegpu/std, and generates an import test for each,
  • modified the CI to run the generate-tests.ts,
  • disabled webpack by default, so now only tsdown runs on CI (because tsdown takes 10 seconds, and webpack takes 6 minutes),
  • made treeshake-test runnable from the Actions menu (generates a summary instead of a comment, and runs webpack as well),
  • modified the results message to include 3 tables: "interesting" static tests results, "interesting" dynamic (generated) tests results, and all test results (a result is "interesting" if it undefined on target branch, or differs by at least 0.5% between branches).

The .yaml must be on main branch for the "Run workflow" button to become visible, I tested it on a repo fork.

It should be possible for files to be virtual, not committed to the file system.

Also, in case you haven't yet thought about displaying the data concisely, maybe we should default to only showing outstanding differences in values (above a certain threshold)? That way we won't be desensitized to these messages.

Pull request overview

This PR enhances the treeshake testing infrastructure by adding dynamic test generation for TypeGPU entry points. It generates import tests for all exports from typegpu, typegpu/data, and typegpu/std packages, and updates the CI workflow to support both automated PR runs (with only tsdown) and manual workflow dispatch runs (with both tsdown and webpack).

Changes:

  • Added generateTests.ts script to dynamically generate import tests for all TypeGPU exports
  • Refactored test execution into runTests.ts with configurable bundler selection
  • Created ResultsTable class to format comparison results with "interesting" and "all results" tables
  • Modified CI workflow to support manual runs with webpack and automatic PR runs with only tsdown

generateTests.ts needs workspace typegpu import to know what exports to generate tests for. And in typegpu, we use typescript syntax unsupported by node
