I need to test my site on mobile and tab devices. But I don't have any real device for it. Please help me to find a cloud device testing tool.
Also BrowserStack offers a similar service, but on virtualized devices. The other providers give the feelings its on real devices, but they could be virutalized too. This might also be something you could do yourself for free: http://developer.android.com/tools/devices/emulator.html
Also check the Ripple Emulator if your main focus is to test how your-sites look at different resolutions and mobile-browser features.
Please see if below links are of any help to you:
Main providers of cloud services for mobile testing: like Perfecto Mobile, Keynote DeviceAnywhere, SOASTA, CloudMonkey and more can be found here. Moreover you can also find some examples of other mobile application testing tools.
Here you can find companies providing cloud testing services or are involved in cloud testing services.
It depends on what exactly you are trying to check.
Worth checking out Mobile Device Labs right now in my opinion:
TestDroid TestObject (Sauce labs) Perfecto Mobile NativeTap Kobiton Amazon AWS Device farm Google FireBase Xamarin Test Cloud Experitest Samsung Developers Lab pCloudy BrowserStack
There's also a crowdtesting option. You can basically hire remote testers from a specific country which will have specific mobile device. It will be quite cheap if you want to do for example one test case, or short exploratory testing session.
