How does a typical mobile testing framework function?

A standard mobile testing framework is divided into three segments, namely:

Application Package: This is the target mobile app that requires testing.
Test Case Runner: It is an instrumentation test-runner for the target app, containing an SDK tool (for building tests) and an API provider (for writing the program).
Test Package: There are two classes, known as Test Cases and Mock Objects. Test Case classes comprise test methods, whereas the Mock Objects include mock data and sample inputs for the test cases

Q - Which languages can Appium support?

Appium supports languages capable of supporting HTTP requests. These include Java, JavaScript, Node.js, Python, PHP, Ruby, Perl, among others.

Q. Explain some of the ADB commands used for Mobile testing with Appium?

Ans: Check this POST_HERE on all ADB commands used in Mobile Testing with Appium

Q - What are some limitations of using Appium?

While Appium has many functionalities and advantages, there are some shortcomings to using this automated testing framework for mobile app testing. Here are some of them:

It is not possible to test Android versions lower than 4.2.
The switching action of an app from the web to native and vice versa is tricky to navigate with Appium.
You cannot run Appium Inspector on Microsoft Windows.

Q - What do you mean by an Appium Inspector?

Appium Inspector is similar to Selenium’s IDE record and Playback tools. While Selenium is an automation framework for web applications run on browsers, Appium is a suitable tool for apps that run on mobile devices.

Q - Differentiate between Simulators and Emulators.

Simulation is concerned with modelling the underlying state of the target. In an ideal case, you can observe all the original features in a simulation. On the other hand, emulation involves imitating the externally observable behaviour of the target. While the external state of the emulation matches the target, the same is not true for internal properties.

Simulators and emulators create room for running quick and easy tests inside flexible, software-defined environments without needing to set up a hardware device.

Q - How to Automate Gestures on Mobile? TouchAction Appium: Swipe using Touch Actions in Appium?

Appium supports many gestures as mentioned below, refer to the post HERE to understand how to use the gestures in your automation script,

Tap on an element.
Tap on x, y coordinates.
Press an element for a particular duration.
Press x, y coordinates for a particular duration.
Drag(Swipe) one element to another element.
Multitouch for an element.

Q - Explain Locators with examples.

One can identify the elements of a mobile application through some properties, some of which are standard in nature. The standard app properties are referred to as Locators, for example, ID, name, accessibilityID, className, XPATH, etc.

Q- What is the use of Appium doctor?

Q - How does FindElement differ from FindElements?

FindElement checks the availability of a specific element in the application UI screen. FindElements can locate multiple elements.

Another difference between the two is that FindElement throws an exception upon not finding any element, but FindElements returns a 0 size array.

Q - Define implicit and explicit wait in Appium.

On certain occasions when there is a delay in loading elements on the application screen, Appium provides the options of Implicit and Explicit Wait, which add a delay for a specified time and for specific conditions, respectively.

Q- How to take a specific element screenshot with Appium?

Ans: Steps to take a specific element screenshot using Appium?

Q - What are the prerequisites for automation testing?

First and foremost, you have to segregate the test cases that you want to automate. Depending on your needs, you prepare the test data and write reusable functions that would be frequently used in your test cases. Then prepare the test scripts and apply loops and conditions as you go along.
