问题描述
Mocha支持it.only语法以减少运行的测试量.在我们的团队中，开发人员可能会在代码库中临时使用it.only.
Mocha supports it.only syntax to reduce the amount of tests to run. In our team, a developer might use it.only temporally within a code base.
现在，偶然发生了这样的only测试被批准和部署的情况.这导致构建服务器仅快乐地运行一个测试，并宣布构建成功.
Now it happened that such an only test was approved and deployed by accident. This led the build server to happily run only one test and to declare that build a success.
我的问题现在变成:有没有办法告诉摩卡咖啡?
My question now becomes: Is there a way to tell mocha:
它应该只允许在开发人员的计算机上使用only吗?可以使环境意识吗，以便所有测试始终在构建机器上运行，或者only测试用例也将作业声明为失败.
It should only allow only on a developer's machine? Can it be make environment aware so that either all tests always run on a build machine or an only test case would also declare the job a failure.
(我知道有多种方法可以减少由mocha运行的测试量.例如，在WebStorm中，可以在不更改代码的情况下在项目中运行测试的子集.问题的范围是考虑到以下事实:开发人员可以使用it.only，他们可以自由使用.我想检测这种更改是否会潜入代码库.)
(I know that there are different ways to reduce the amount of tests run by mocha. E.g. within WebStorm one can run a subset of tests within a project without changing code. The scope of the question is to allow for the fact that a developer might use it.only and they shall be free to do so. I want to detect if such a change might sneak its way into the codebase though.)
推荐答案
在您的CI上，应该使用 forbid-only 标志.
On your CI, you should run mocha with the forbid-only flag.
--forbid-only causes test marked with only to fail the suite
根据您的设置，它可能看起来像:
Depending on your setup it may look like:
mocha --require babel-register --recursive tests/unit --forbid-only
开发人员仍然可以选择不带标志运行测试套件.
A developer still may chose to run the test suite without the flag.
