Understanding the Basics of Appium and Selenium Testing
What is Appium?
Appium is one of the most popular mobile automation testing tools utilised for performing testing on mobile browsers and mobile apps. With Appium, testers can validate compatibility issues, response times, useability issues and cross browser features on different devices.
This framework offers strong support for various programming languages like Python, Java, PHP, and even Perl. It accommodates Android OS, iOS and Firefox OS application testing.
You can conduct automation testing in the Appium framework using simulators, emulators and mobile devices. A key advantage of Appium is that it doesn’t rely on the mobile device’s OS. It can translate driver commands into different instructions that are not dependent on iOS types.
If you desire to use Appium, you need to have the following tools:
- Eclipse IDE
- Appium Server
- Appium Client Library
- Node.js, Java
- Android Studio
- Selenium Jar
What types of mobile apps can you test using Appium?
There are three types of mobile applications that you can utilise Appium automation in testing. They include:
- Native apps: These apps are developed using IOS, Windows SDKs or Android. They come with good navigation features for mobile app browsers.
- Hybrid apps: This type of app offers a seamless feature in terms of web browser navigation.
- Web apps: Finally, web apps are designed to be accessed by mobile app devices using browsers.
What is Selenium?
Selenium is the most popular open-source automation testing tool for web browsers. This test automation tool allows testers to write their test scripts in different programming languages including Python, C#, Ruby, NodeJS, PHP and others. It is a game changer in the test automation field and happens to be a favourite tool for automation experts for several reasons, one of which is its WebDriver tool.
1. The Selenium WebDriver
The Selenium WebDriver has its own way of executing test scripts by using browser-specific drivers consisting of API, library, Driver, and Framework.
- API: The library houses the API in the WebDriver for language-specific bindings. The Selenium automation tool allows for many third-party bindings.
- Driver: This component plays a crucial role in testing because it opens up the browsers and runs the test script. In other words, the driver significantly enhances Selenium’s automation processes in browsers.
- Framework: WebDriver has a framework that offers support to the library for natural language integration with test frameworks.
2. How Selenium Works ?
WebDriver comes with a local end client that functions by sending commands (written in test scripts) to the browser driver. The browser driver then executes the commands it has received. It is very important to note that test scripts only execute when the WebDriver and the browser driver are connected, although they may not be on the same device.
3. The Selenium Grid
The Selenium Grid is yet another amazing feature of Selenium. It offers several advantages to the test automation tool, like minimizing test runtime since it can execute more than one test script at a time using parallel testing.
The Selenium Grid uses two components to function well: the Hub (server) and the Node (a remote device). The server takes care of all access requests from the WebDriver, while the remote device contains browsers, a remote WebDriver, and a native OS.
How do you set up the Selenium Grid? Well, that is quite easy. Remember we told you that the Selenium automation tool is easy-to-use? We were not playing around. However, scaling it can sometimes be very resourceful. This is why we usually advise testers to deeply consider a lot of things before adopting the Selenium Grid.
4. The Selenium IDE
The Selenium IDE plugin naturally works with Chrome and Firefox browsers. Testers can perform recording with the IDE and carry out different tests on the browser.
The Appium and Selenium Architecture
Appium and Selenium follow a client-server architecture for their automation frameworks.
In the case of Appium, the client libraries allow automation engineers to write test scripts in their preferred programming language. The Appium server acts as a mediator between the test scripts and the mobile devices or emulators/simulators. It receives commands from the test scripts and translates them into actions on the target devices by utilizing the native automation frameworks provided by the respective platforms. The desired capabilities specified in the test scripts help Appium identify the target device or emulator/simulator, and automation drivers specific to each platform interact with the elements on the screen.
Similarly, Selenium utilizes client libraries that enable automation engineers to write test scripts in languages like Java, Python, C#, or JavaScript. The Selenium WebDriver is a crucial component that acts as a driver for interacting with web browsers. It communicates with the browser’s native automation technology to perform actions on web elements.
Automation engineers write test scripts using the Selenium client libraries, and the WebDriver interacts with the chosen browser, supporting various browsers such as Chrome, Firefox, Safari, and Edge. Additionally, Selenium Grid allows for parallel test execution across multiple machines or browsers, facilitating distributed testing.
Therefore, we can say that both Appium and Selenium adopt a client-server architecture. Appium focuses on mobile automation, with the Appium server facilitating communication between the test scripts and mobile devices/emulators. Selenium specializes in web automation, utilizing the WebDriver to interact with web browsers. Both frameworks offer client libraries, enabling automation engineers to write test scripts, and provide various features to enhance the automation process.
