Is it possible to simulate root access when testing without running the tests on two different devices?

I'm starting the studies about android development with Android Studio and I was wondering if it's possible to build applications only running code on a physical device or do I need to emulate others devices in order to avoid errors, etc.?
The Android Studio emulator barely runs in my machine, so I need to know if it is essential for the apps development or if there are other alternatives.
If you need to run on different versions of Android, just what #CrazySports101 mentioned, but also test different screen sizes & resolutions to check UI responsiveness, it would be better to use emulators.
Obviously, you can start development using either a single emulator or physical device, but during your final testing stages, it would make sense to use emulators to test all your device specific usecases.
And yes, there are few limitations with using an emulator, like it cannot emulate network connectivity, other real-time data, such as GPS, sensors, battery issues, etc. Or usecases such as calling, receiving SMS is not possible as well.
If you have a physical device, you can just use that. No need to run the emulator at all. An emulator is mostly used because it is convenient and easy to test different versions of android. For example, some libraries/UI component may behave differently on different phones.
It is better to use a physical device if your app is using radios like Bluetooth etc.
If you just started to learn android studio and your device can barely run emulator, I would recommend you to go for physical device. Emulator makes you possible to try your product on different version of android and screen ratios, but you can not emulate network connectivity, real-time data, GPS, sensors, battery issues, calling, receiving SMS is not possible. But if you are trying to launch a product in a market you should go for emulator as you would need to try your product on different versions as well.
I have Android application which communicates with device using BLE. I want to cover BLE logic with tests.
Is it possible to run unit tests (or maybe instrumentation tests) with real BLE device on real Android device?
Using only Android instrumented tests? I don't see a way of doing that.
Using external elements?
Yes, it is possible, but you need to implement your own 'framework'. I mean you need a way to control the BLE device, a library on CLI for example, this would be done outside the Android instrumentation test so you would integrate the framework to instrumented tests.
I have seen some articles and questions regarding Automation through Appium on multiple Android devices. I know that for Appium to work on multiple devices we need to give the device id to udid in the JAVA code.
what I really want to understand is how will Appium perform the same script on multiple devices? What if a command fails on one device and does not fail on the other device? will there be multiple servers running?
Any help will be appreciated. Thank you :)
Its Possible! But there is no direct approach to do it. We have to start Appium server in different ports(Example: 4723, 4725,...). We have to get the udid of multiple devices connected to the system & have to set the capability.
If a command fails on one device it won't give any effect to other device. Since, We have 2 appium servers running.
Most of the time same test will not fail on some other devices. Some reasons to fail on same platform and different devices might be size of devices and different device behavior in different manufactures.
If you write your test wisely keeping everything in mind then you will have very less test failure because of device.
Also to launch test on multiple device either you can launch multiple appium server or you can launch one server and create multiple sessions of it.
Test failure in one device will not affect test running in another device. As these are using different servers or sessions.
I need to make sure that our software runs smoothly on every type of mobile android and ios device that are out there. Is Katalon studio capable of running tests on different types of devices without physically having those devices?
yes, you can run katalon in a different type of device or you can use kobiton device but it charges you money.
I set up the automator and implemented some test cases.
I can run it via adb comandline instruction. But is there a way to run it directly in the Eclipse environment?
Like JUnit test cases?
As standard, UI Automator tests are compiled and built into a jar file, on a desktop computer, they are then deployed to the device by pushing the jar file to the device using adb. They are then run on the device, in the Android runtime by using adb shell uiautomator
I have not seen anyone else trying to run the test cases directly on the device rather than building them following the approach Google (Android) document. It might be possible, however you may have to work hard to discover whether your approach is possible or viable. UIAutomator is distinct and separate from the Android InstrumentationTestCase framework. Instead it interacts with the GUI and has the advantage of being able to interact with a wide range of apps, including things like the inbuilt Settings UI on Android devices.
