+If you use the mocking library [proxyquire](https://github.com/thlorenz/proxyquire), or otherwise need to define path strings which aren't direct arguments to `transformFunctions`, you have a problem: the plug-in won't convert them.
 
 Because proxyquire expects paths not just as direct arguments, but also as object keys, simply adding proxyquire to `transformFunctions` isn't enough:
 
 ```js
-const { functionToTest } = proxyquire('~/modifiedPathToTestedModule', { // this path will be converted
-    '~/modifiedPathToDependency': { mockVersionOfDependency } // this path won't be converted
+const { functionToTest } = proxyquire('~/modifiedPathToTestedModule', {

+  '~/modifiedPathToDependency': { mockVersionOfDependency }, // this path won't be converted
 });
