我遇到了一个 test_helper 文件的问题，该文件可以正常工作。这是一个我会在一段时间后回来的项目。错误和文件与 package.json 一起在下面，因为我怀疑它可能是编译器导致了问题。

错误

SyntaxError: /Users/mikewalters/Projects/video-
frontend/test/test_helper.js: Unexpected token (20:4)
18 | function renderComponent(ComponentClass, props = {}, state = {}) {
19 |   const componentInstance =  TestUtils.renderIntoDocument(
> 20 |     <Provider store={createStore(reducers, state)}>
   |     ^
21 |       <ComponentClass {...props} />
22 |     </Provider>
23 |   );

test_helperjs

chaiJquery(chai, chai.util, $);

  const componentInstance =  TestUtils.renderIntoDocument(
    <Provider store={createStore(reducers, state)}>
      <ComponentClass {...props} />
    </Provider>
  );

  return $(ReactDOM.findDOMNode(componentInstance));
}

$.fn.simulate = function(eventName, value) {
  if (value) {
    this.val(value);
  }
  TestUtils.Simulate[eventName](this[0]);
};

}

$.fn.simulate = function(eventName, value) {
  if (value) {
    this.val(value);
  }
  TestUtils.Simulate[eventName](this[0]);
};

export {renderComponent, expect};

包.json

"scripts": {
    "start": "node ./node_modules/webpack-dev-server/bin/webpack-dev-server.js",
    "test": "mocha -r mock-local-storage --compilers js:babel-core/register --require ./test/test_helper.js --recursive ./test",
    "test:watch": "npm run test -- --watch",
    "coverage": "babel-node ./node_modules/.bin/isparta cover --include 'src/**/*.js*' _mocha"
  },

这些测试之前已经工作过，而且它甚至没有进入测试的事实让我相信编译器或包发生了变化。但我无法在网上找到任何关于这个问题的信息。

我错过了一个 .babelrc 文件。最后添加了这个，它开始工作了

{
 "presets": [ "react","es2015","es2016","stage-0" ]
}
