camc314 65cda29177 fix(transform_conformance): record missing expected errors (#25306 )

Fix the transformer conformance runner incorrectly marking a fixture as passed that specified `throws` when Oxc produces no error.

Failed conformance cases now always record a diagnostic. This exposes previously hidden failures in the Babel snapshot, including the nested ambient-module fixtures.

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

cargo run -p oxc_transform_conformance

or watch for changes

just watch 'cargo 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, which need to be executed by a runtime.

These tests are executed with Node.js and Vitest. Apply the --exec flag:

cargo run -p oxc_transform_conformance -- --exec

This is also available as:

just test-transform

The failing test cases are listed in:
