+ | Test application: | ||
+ | * We need a simple graphical application that is likely to be already installed on the remote machine | ||
+ | * The **test is declared successful** if we get a new window and we can interact with it.\\ Note: some applications may start with their window iconified, and you may have to check the part of your screen where the iconified windows go... | ||
