Webpack config to make ember-cli-page-object work with embroider optimized

webpack.config.js

module.exports = {
  module: {
    rules: [
      // ember-cli-page-object's compatiblity module is a wrapper around
      // @ember/test-helpers that synthesizes its methods using older APIs when
      // in an app with an old/missing version of @ember/test-helpers. The
      // dynamic-ness disagrees with embroider's staticAddonTestSupportTrees
      // flag, so since we know we will only run in environments with a
      // sufficiently new @ember/test-helpers, string-replace the compatiblity
      // module to statically re-export @ember/test-helpers, and also to export
      // the named wait helper, which was an older name for settled() (and will
      // never actually be called anyway).
      {
        test: /\/ember-cli-page-object\/test-support\/-private\/compatibility\.js$/,
        loader: 'string-replace-loader',
        options: {
          search: /^[\s\S]+$/,
          replace: [
            "export * from '@ember/test-helpers';",
            "export { settled as wait } from '@ember/test-helpers';",
          ].join('\n'),
          strict: true,
        },
