How to tell JSHint to ignore all undefined variables in one file?

Question

In Karma tests, there are a lot of global variables and functions, which JSHint complains about (it is integrated into my editor). How can I tell JSHint to ignore all undefined variables in this one specific file? I would expect `/* jshint undef: false */` to turn off these warning, but it doesn't.

Accepted Answer

The correct way to tell JSHint about globals is to use the `globals` directive. For example:

```
/*globals globalFunction, anotherGlobal, oneMore */
```

This will prevent "{a} is not defined" warnings when JSHint encounters any of the listed identifiers.

Alternatively, if you really want to ignore all "not defined" warnings in that file, and you're using JSHint 1.0.0 or above, you can simply turn off that specific warning:

```
/*jshint -W117 */
```
