Transformation Conformance Test Runner

Execution

This test runner uses the transformation plugin test suite from the Babel repository.

Additional tests are in the tests directory.

The failing test cases are listed in:

To get started, run

bash

cargo run -p oxc_transform_conformance

or watch for changes

bash

just watch 'run -p oxc_transform_conformance'

To filter for a specific test case, apply the --filter path option, e.g.

bash

cargo run -p oxc_transform_conformance -- --filter react/arrow-functions

The Babel test suite contains many exec.js files, which need to be executed by a runtime.

bun is the preferred way to execute these tests, which you may install them via https://bun.sh/docs/installation.

Once bun is installed, apply the --exec flag:

bash

cargo run -p oxc_transform_conformance -- --exec

The failing test cases are listed in babel_exec.snap.md.
