Standard not working in tests

[amaurymartiny]

What version of standard?

11.0.1

What operating system, Node.js, and npm version?

macOs High Sierra
node v10.1.0
npm v6.1.0

What did you expect to happen?

Following #122 (comment), I would expect that , by putting "env": [ "mocha" ] to the package.json, I could use standard to lint my test files.

What actually happened?

$ yarn lint
yarn run v1.7.0
$ standard src/main.test.js
standard: Use JavaScript Standard Style (https://standardjs.com)
  /Users/amaurymartiny/Workspace/standard-in-tests/src/main.test.js:2:3: 'expect' is not defined.

As far as I know, expect is not part of mocha. Setting env: mocha adds describe and it, which seems to work for you.

Yep!

eslint uses the globals package to get the mocha globals and I don't see expect listed there :)

If you're using some assertion library that has expect as a global, you can tell standard to ignore it using one of these ways:

1. put this at the top of the JS file that references expect: /* global expect */

2. add this to package.json:

 "standard": {
    "globals": [ "myVar1", "myVar2" ]
  }

Hope this helps! I'm closing this issue, but feel free to reply if you have other questions!
