// This tests simulated drag and drop of files into the add-ons manager.

// Tests are only simulations of the drag and drop events, we cannot really do

// Instead of loading EventUtils.js into the test scope in browser-test.js for all tests,
// we only need EventUtils.js for a few files which is why we are using loadSubScript.
