/*
 * A helper script which enables using Sinon.JS version 1 or 4 within QUnit version 1 or 2. QUnit
 * tests are run in a Sinon sandbox. This allows creating Sinon spies, stubs and mocks via this. The
 * sandbox is created before running beforeEach and is verified and restored when afterEach
 * including all returned promises is finished. This sandbox can be used universally in beforeEach,
 * the test itself and afterEach. It is available as <code>this._oSandbox</code>.
 *
 * This script requires that QUnit and Sinon.JS have been loaded via <script> before. (The global
 * properties QUnit and sinon must exist.)
 *
 * BEWARE: This script does not support QUnit.module with a nested callback function.
