If you run Windows, it is easy to overlook the Safari web browser when testing a web application. Ideally, you can use this limitation as an excuse to buy a Mac. However, if your employer doesn't buy it, consider the Swift Browser. It uses the same rendering engine used in Safari but runs on Windows. I installed it and, although it is very poor functionality-wise, it worked. Hint: to get the address bar, you may need to click the tiny triangle in the upper right side of the page (see screenshot).
