/**
 * Makes sure that the new function "getDefaultApp" will return the correct application under test from the apps store
 * or peacefully returns null if the app is not in the apps store. If the laucch activity is also specified with appName
 * then just return the appName so it can be installed to the apps store.
 *
 * The tests will cover these scenarios:
 * <ul>
 *
 * <li>If app does not exists in the apps store and the launch activity is specified, then just return
 * the request string as app under test so it can be installed to the device by the SelendroidStandaloneDriver. </li>
 * <li>If app does not exists in the appstore, and the launch activity is not specified then return null.</li>
 * <li>If appName and appVersion are specified then return the app under test as "appName:appVersion" if it is found in the
 * apps store or null if it is not.</li>
 * <li>If appName is specified but not the appVersion then return the latest version of the apps in the apps store as app
 * under test in the format of "appName:appVersion" or null if app is not found in apps store.</li>
 * </li>
 * <ul>
