appium testing interview questions: 39 Appium Interview Questions (With Sample Answers)


Answer ( 1 )


    Appium is an open source test automation framework for automating native, mobile web, and hybrid applications on iOS and Android platforms. It uses the WebDriver JSON wire protocol to drive the browser or application under test, which means that you can write tests using any language that supports WebDriver. Appium’s server runs on Node.js and connects to devices via Selenium WebDriver’s RemoteWebDriver

    1. What is Appium?

    Appium is an open source test automation framework for mobile applications. It was developed by Sauce Labs and can be used on both Android and iOS platforms.

    Appium works with Selenium WebDriver, which allows you to write tests in any language that supports WebDriver (JavaScript).

    2. Which is the best way to run tests in a CI/CD environment?

    • Use a CI server like Jenkins.
    • Run the tests in parallel.
    • Use TestNG or JUnit as your test runner.

    3. What are Selenium WebDriver and Appium?

    Selenium WebDriver is a tool for automating web applications. It allows you to write tests in a programming language of your choice and then run them on a variety of platforms, like browsers and mobile devices.

    Appium is an open source framework for automating native, hybrid and mobile web apps. Appium provides an API for writing tests in Node JS or Java (Android) that can then be run on any device where there is an Appium server installed: iOS Simulator/Device; Android Emulator/Device; Chrome browser; Firefox browser etc…

    4. How can you use Node.js in your Appium tests?

    Node.js is a JavaScript runtime environment, which means it allows you to run JavaScript code on your machine. You can use Node.js as an API server for your mobile app and test it with Appium or any other automation tool. This would allow you to write tests in any language that supports JavaScript such as Java, PHP or Ruby etc., instead of writing them in Objective-C or Java which are native languages used by iOS and Android apps respectively.

    Node is also used by many CI/CD tools like Jenkins because it provides out-of-the box support for various programming languages including Python (PyPi), Ruby (Gem Bundler), PHP (Composer) etc., making them very flexible when it comes to automating any kind of task regardless whether it’s related with testing or not!

    5. What do you mean by “test automation pyramid”?

    Test automation pyramid is a concept of test automation. It is also known as “test pyramid”. The test automation pyramid explains that you should write more and more unit tests, followed by integration tests and so on, until you reach user acceptance testing at the top of your pyramid.

    The idea behind this approach is to ensure that each layer of your application has been tested thoroughly before moving on to the next layer. This helps reduce errors and increase quality assurance in your codebase over time by ensuring all parts work together as expected before moving onto any new functionality or fixes within existing codebases

    6. What are the various parameters available to configure node servers via command line?

    It is also possible to configure node servers via command line. The following parameters can be used:

    • port: The port number which will be used by Appium to connect with the server.
    • host: The hostname or IP address of your test server. If you are using an HTTP proxy, then enter its address here as well (without any port number).
    • baseurl: This is a relative path from your project directory where all resources reside (such as jar files, JavaScript files etc.). If not specified then it defaults to ‘/’. You can also specify multiple locations separated by commas(,) if required like ‘http://www1/,http://www2/.

    7. Which version of node is recommended for running appium tests?

    The recommended version of NodeJS to run your appium tests is either 10.x or 11.x, depending on the OS you are using.

    8. Explain what is a ‘test file’ in webdriver?

    A test file is a file that contains a set of test cases.

    It’s executed by WebDriver, which is an automation tool for web applications. It’s written in Java script and should be created in the same folder as the app being tested.

    9. Can you explain about the difference between beforeAll() and afterAll() functions of selenium webdriver? (with example)

    Before we dive into the difference between beforeAll() and afterAll(), let’s first understand what these functions actually do.

    • The beforeAll() function is used to set up the environment for a test. It can be used to initialize variables, create objects, open web pages etc., which will be used later during execution of different tests.
    • The afterAll() function cleans up anything created by preceding callbacks in any given suite (or test). This helps avoid common issues like leaking file handles or database connection pools that can cause problems when running multiple tests at once on CI servers such as Jenkins or TravisCI
