An emulator is a program that duplicates or mimics the functions of one system on a different system. Emulators exist in many forms and have different uses. An iPhone emulator can be used to test or run apps for the smartphone, and it is of particular importance to app developers. There are various emulators that you can download to test your apps, but for the purpose of this tutorial, we will use MobiOne Studio. MobiOne is one of the most popular programs of its kind and has received high ratings from several critics in the tech industry.
Before you jump into downloading MobiOne, here is a little background on the program. While MobiOne Studio includes an iPhone emulator and that will be the focus of this tutorial, it also can be used to design iPhone apps and websites. It allows you to create these without needing to be an expert on code or other highly technical items, and it uses simple drag and drop technology. MobiOne runs on Windows, so it eliminates the barrier that comes with similar programs like the iPhone SDK which require you to have a Mac. If you have compatibility concerns, don't, because MobiOne incorporates support for JavaScript, HTML5, and CSS3.
Now that you see the additional services MobiOne provides, let's focus on the testing solutions it can offer. The program's iPhone emulator is referred to as the MobiOne Test Center. On the surface, this feature allows you to click around and test the various parts of your app to make sure that it works properly. As you go a bit deeper, you will notice that the emulator can also give you more technical details about your app. You can view the app's code, its resources, and also troubleshoot any problems that you encounter. Perhaps the best part of MobiOne is that it allows you to send your app to your iPhone so that you can see how it behaves on the real thing. Some other emulators do not have this functionality, so you are limited when it comes to seeing your app in its true form.
