The art of mobile testing is increasingly important for any company that wants to remain competitive. Mobile application testing is a process by which application software developed for handheld mobile devices is tested for its functionality, usability and consistency. Mobile application testing can be an automated or manual type of testing. My presentation would be an introduction to automated mobile testing, and I would like to show to participants how to set up one project and use C# with Appium for testing mobile application. I would like to pay attention to them on problems and solutions in setup and to show a small example of one Appium project.
