Mocha 不会识别 JSX
Mocha will not recognise JSX
我正在尝试使用 mocha 和 enzyme 更新我的单元测试。我正在测试的代码是在 ES6 中,使用 JSX 和 React。
我无法让 mocha 在我的测试脚本中的 JSX 上不出错。
测试脚本:
import React from 'react';
import assert from 'assert';
import { shallow } from 'enzyme';
import SamplePageMain from '../SamplePageMain';
describe('<SamplePageMain />', () => {
var samplePage = shallow(<SamplePageMain />);
it('should render', function () {
assert.notEqual(samplePage, null);
});
});
gulpfile.js:
require('babel-core/register');
...
gulp.task('test', function() {
return gulp.src('scripts/**/test/*.js', {read: false})
.pipe(mocha());
});
输出为:
gulp test

[16:19:06] Starting 'test'...
[16:19:06] 'test' errored after 62 ms

我已经通过 browserify 运行 将源代码 运行 测试成功 运行 并将其放在测试目录中以证明它不是 mocha/enzyme 本身。我的问题只是想正确使用 gulp 魔法。
对于 Babel 6 的用户来说,这是一个非常普遍的问题,它本身 (babel-core) 不会做任何事情。它要求在转译过程中向其提供转换/插件。
Babel 提供了常用插件包作为预设。 React 项目常见的是 babel-preset-2015
、babel-preset-react
和 babel-preset-stage-0
。在 npm 安装它们之后,添加一个看起来像这样的 .babelrc
配置文件:
{
"presets": ["react", "es2015", "stage-0"]
}
对于 gulp 的摩卡咖啡,请查看此堆栈 。
