Query: In order to safeguard a mobile website from SPAM/Bots without resorting to user-unfriendly CAPTCHA, we are considering disabling onClick events at the server side while still permitting onTouch events. Can bots emulate the onTouch function, thus ensuring that only human users can access the site?
When looking at the UI programming models and APIs provided by browsers for developers, it becomes apparent how easy it is for hackers and spammers to mimic click/touch events on a web application. One important thing to remember is that JavaScript callbacks can replicate onClick event handlers as well as onTouchStart, end, and drag functionalities.
In simpler terms, the touch/click APIs share similarities in language but vary in implementation based on the browser being used.
Absolutely! It is possible to control an Android phone or tablet using Selenium. While I have not personally tried it, there are resources available that demonstrate how it can be achieved. You can check out this answer for more information: Selenium and Touch Events
The Selenium Android driver provides TouchActions that allow you to simulate touch events:
new TouchActions(driver).down(x, y).move(200, 50).perform();
You will need access to an Android device to carry out these actions. Alternatively, the functionality may also be tested using the Android emulator included in the Android SDK.
