  -### Tests are slow when leveraging automocking
  -
  -Whether via [`automock: true`](configuration.html#automock-boolean) in config or
  -lots of
  -[`jest.mock('my-module')`](jest-object.html#jestmockmodulename-factory-options)
  -calls in tests, automocking has a performance cost that can add up in large
  -projects. The more dependencies a module has, the more work Jest has to do to
  -mock it. Something that can offset this performance cost significantly is adding
  -a code transformer that moves `import` or `require` calls from the top of a
  -module, where they are always executed, down into the body of the module, where
  -they are usually not executed. This can lower the number of modules Jest has to
  -load when running your tests by a considerable amount.

  -To transform `import` statements, there is
  -[babel-plugin-transform-inline-imports-commonjs](https://github.com/zertosh/babel-plugin-transform-inline-imports-commonjs),
  -and to transform `require` statements, there is
  -[Facebook's `inline-requires` babel plugin](https://github.com/facebook/fbjs/blob/master/packages/babel-preset-fbjs/plugins/inline-requires.js),
  -which is part of the `babel-preset-fbjs` package.

  -### I'm using npm3 and my node_modules aren't properly loading.
  -
  -Upgrade `jest-cli` to `0.9.0` or above.
  -
  -### I'm using babel and my unmocked imports aren't working?
  -
  -Upgrade `jest-cli` to `0.9.0` or above.
  -
  -Explanation:
  -
  -```js
  -jest.dontMock('foo');
  -
  -import foo from './foo';
  -```
  -
  -In ES6, import statements get hoisted before all other
  -
  -```js
  -const foo = require('foo');
  -jest.dontMock('foo'); // Oops!
  -```
  -
  -In Jest 0.9.0, a new API `jest.unmock` was introduced. Together with a plugin
  -for babel, this will now work properly when using `babel-jest`:
  -
  -```js
  -jest.unmock('./foo'); // Use unmock!
  -
  -import foo from './foo';
  -
  -// foo is not mocked!
  -```

  -See the [Getting Started]GettingStarted.md#using-babel) guide on how to enable
  -babel support.
  -
  -### I upgraded to Jest 0.9.0 and my tests are now failing?
  -
  -Jest is now using Jasmine 2 by default. It should be easy to upgrade using the
  -Jasmine [upgrade guide](http://jasmine.github.io/2.0/introduction.html).
  -
  -If you would like to continue using Jasmine 1, set the `testRunner` config
  -option to `jasmine1` or pass `--testRunner=jasmine1` as a command line option.

  ### Compatibility issues
  Jest takes advantage of new features added to Node 6. We recommend that you
