如何从一个“npm 测试"运行 mocha 和 mocha-phantomjs 测试node.js 中的命令? [英] How to run mocha and mocha-phantomjs tests from one "npm test" command in node.js?

问题描述

我有几个可以在 node.js 环境和浏览器中运行的节点包.现在我有两个单独的测试(针对每个环境).仅使用 npm test 命令运行这些测试的最佳方法是什么?我也想将这些包添加到 travis.

I have got few node packages which works in node.js environment and also in browser. Now I have got two seperate tests (for each environment). What is the best way to run these tests with just npm test command? Also I want to add these packages to travis.

我正在使用 mocha 和 mocha-phantomjs.

节点测试命令

node ./node_modules/mocha/bin/mocha ./test/node/index.js --reporter spec

浏览器测试命令

node ./node_modules/mocha-phantomjs/bin/mocha-phantomjs ./test/browser/index.html

我的尝试:

1. 将这些命令添加到以分号分隔的 npm test 脚本中
   • 问题:当第一个脚本有错误但第二个脚本没有错误时，命令以 0 退出，travis 构建通过.

1. Add these commands into npm test script seperated with semicolon
   • Problem: When there is an error in first script but no error in second script, command exited with 0 and travis build passed.

• 问题:用户必须手动运行两个独立的测试脚本.

• Problem: Users have to run manually two independent test scripts.

• 问题:感觉不太对，所以我想知道是否有更好的方法.

• Problem: It just does't feel right, so I wanted to know if there is some better way.

推荐答案

我喜欢以下内容:

  "scripts": {
    "test": "npm run test-node && npm run test-browser",
    "test-node": "mocha -R spec ./test/node/index.js",
    "test-browser": "mocha-phantomjs ./test/browser/index.html"}

&& 仅在第一个通过时运行第二个，如果需要，您可以单独运行.请注意，npm 始终使用 相对 mocha (在 node_modules 中)，而不是全局的，所以直接调用 mocha 和 mocha-phantomjs 没有坏处.你可以使用 mocha 的 -b 选项来提高效率，它会在遇到错误时立即退出.

The && only runs the second if the first passes, and you can run either separately if you want. Note that npm always uses the relative mocha (inside node_modules), not the global one, so there's no harm in just calling mocha and mocha-phantomjs directly. You can be even more efficient with mocha's -b option for bail, which will quit as soon as it encounters an error.
