defineTest can not resolve async transform

[shiyangzhaoa]

If the transform is async, defineTest run error, because the defineTest only support sync, output is promise

Would you be able to up to github a temporary repository that reproduces the error?

git clone jscodeshift

// sample/reverse-identifiers.js
function transformer(file, api) {
  const j = api.jscodeshift;

  return j(file.source)
    .find(j.Identifier)
    .replaceWith(
      p => j.identifier(p.node.name.split('').reverse().join(''))
    )
    .toSource();
}
// replace with async
function transformer(file, api) {
  const j = api.jscodeshift;

  const source = j(file.source)
    .find(j.Identifier)
    .replaceWith(
      p => j.identifier(p.node.name.split('').reverse().join(''))
    )
    .toSource();
    
   return Promise.resolve(source);
}

run yarn test

Hitting up against this myself. It looks like the PR was closed out without a resolution?

We just started running into this when the dependabot updated to @types/[email protected]. Has anyone managed to work around this?
