Transformation Conformance Test Runner

Execution

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

The failing test cases are listed in ./babel.snap.md

To get started, run

cargo run -p oxc_transform_conformance

or watch for changes

just watch 'run -p oxc_transform_conformance'

Options

--filter

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

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

--exec

The babel test suite contains many exec.js files, they 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:

cargo run -p oxc_transform_conformance -- --exec

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