Dunqing 35f03db464 fix(transformer): ArrowfunctionExpression's expression is true but has more than one body statement (#5366) 
close: #5363

We insert the new statement here, but it's broken if it a `() => x;`, we need to transform it to `function () { return x }`

8d565d5b23/crates/oxc_transformer/src/es2020/nullish_coalescing_operator.rs (L59-L76)

I don't where we should put the fallback logic, It's useful for all plugins. We had already done the same thing in the react refresh plugin.

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.
