摩卡只运行一个测试文件 [英] Mocha only running one test file

问题描述

我的Mocha测试工作正常，但是当我添加一个新模块（和测试）时，mocha停止运行我的所有测试文件，现在只运行单个新测试。

My Mocha tests were working fine, but when I added a new module (and test), mocha stopped running all of my test files and now only runs the single new test.

我的测试脚本：

env NODE_PATH=$NODE_PATH:$PWD/src mocha --recursive --compilers js:babel-core/register src/**/*.test.js --require babel-polyfill

我的项目结构如下：

/src
  /components
    /component-name
      index.js
      component.js
      component-name.test.js
      style.scss
  /util
    /module-name
      index.js
      module-name.test.js
  /some-other-module
    index.js
    some-other-module.test.js

我在 / components 和 / util中进行了多次测试并且一切正常，但当我将模块放入 / src （如 / some-other-module ）， .tes其中包含t.js 文件，Mocha只运行该测试文件而不运行其他文件。

I had several tests in /components and /util and everything worked fine, but when I place a module into /src (like /some-other-module) with a .test.js file in it, Mocha only runs that test file and none of the others.

推荐答案

在传递给Mocha的模式周围加上单引号以防止它被shell解释：'src / ** / * .test.js'

Put single quotes around the pattern you pass to Mocha to prevent it being interpreted by your shell: 'src/**/*.test.js'

如果没有引号，shell会尝试扩展该模式并成功。扩展的结果是 src / some-other-module / some-other-module.test.js ，这是传递给Mocha的内容。

What happens is that, without the quotes, your shell tries to expand that pattern and is successful. The result of expansion is src/some-other-module/some-other-module.test.js and this is what is passed to Mocha.

在创建该文件之前，shell仍尝试扩展模式但未成功并将模式保持原样。所以Mocha得到 src / ** / * .test.js ，其中Mocha本身被解释为一个glob。

Before you created that file, the shell still tried to expand the pattern but was not successful and left the pattern as-is. So Mocha got src/**/*.test.js, which Mocha itself interpreted as a glob.

如果您想知道，在Bash中，除非打开 globstar 选项， ** 相当于 * 。

In case you wonder, in Bash, unless the globstar option is turned on, ** is equivalent to *.
