+/**
+ * setWindowLocation allows for setting `window.location`
+ * (doing so directly is causing an error in jsdom)
+ *
+ * Example usage:
+ * assert(window.location.hash === undefined);
+ * setWindowLocation('http://example.com#foo')
+ * assert(window.location.hash === '#foo');
+ *
+ * More information:
+ * https://github.com/facebook/jest/issues/890
+ *
+ * @param url
