What is Appium?
Hello Folks! We all are living in the Twenty-first generation and using mobile for each and everything. It is an agreeable fact that mobile has become the most important part of our life. As the use of mobile is more the demand for mobile applications is also high. As mobile applications are convenient there are almost 2 million apps in Android and IOS.
Converting current software testing into mobile version came in to picture for creating apps in mobile software and the need to test these applications has aroused. This is a repetitive task to test the mobile app hence it would be better if there is an automated testing system for testing these mobile applications. Thus appium came in to picture. There are many automated tools in the market but appium is the widely used one.
Let’s not delay and learn about the appium automation tool in a step-by-step process
It can be defined as an open source tool for all mobile application automation which was launched in 2012. With the help of appium automation, this automation can be done with ease
This can be run on operating systems such as
- Firefox OS
It is cross-platformed as well It means we can write tests in any platform using the same Application Programming Interface. Means we can write the test code in IOS and the same test can be used for windows phone, android app. This, in turn, results in large re-usable code which is time-saving.
Another beautiful feature of appium is, recompilation doesn’t involve automation of application. That means without access to the automation code this can be used.
Let’s dive right in and know about appium. The most important aspect of appium is the client/server nature. Understanding appium can be understood easily by appium architecture.
Server: When selenium RC is used we will generally find out that appium works in a similar line like selenium server in selenium RC, it provides communication between mobile device and client. Appium is scripted in Node.js so there is no need to install it again
A REST API is exposed once the Appium server is started to the client. A client starts a session with JSON ‘desired capabilities’ object. A connection is set between client and server.
How Appium works?
Before using this, we need to follow the necessary steps to make it work properly.
Installation of JDK, Android SDK Studio
Next, Eclipse has to be installed and for Eclipse install TestNg
Selenium server JAR, Appium Library client and Appium desktop has to be installed.
An HTTP Server which can be written by the usage of a platform node.js that makes the iOS and Android operating system to work with the utilization of a JSON wire protocol is known as Appium.
Once the Appium is been installed, our machine has to be set up with a server which releases REST API.
Then from the client, it will be receiving a connection and a command request, Appium starts executing the command on various mobile operating systems such as Android or iOS.
The response is an HTTP response, for executing HTTP response it makes use of the mobile test automation framework to bring a user interface output.
Why choose Appium?
With the plenty of mobile automation tools in the market, Appium comes with its own unique feature that drives Android/iOS systems to give user-friendly flexibility. Appium has its extension to work in native and hybrid mobile applications. Appium can be written in any language and can be used for automated purposes without modifying anything. And Appium code can run in various devices which are the best reliable and scalable choice for the automation of mobile.
Pros and Cons
The pros and cons of appium are given below in a detailed format
- It is a free and open source
- These provide cross-platform solutions for native and hybrid apps
- It is compatible with JSON web-driver and Grid
- Testing based on cloud is supporting using testdriod
- Programming languages such a C#, Java, PHP, Python, Ruby are supported by appium
- App Automation is possible by using appium
- It enables to evaluate cross-platform mobile apps without recompiling the code
- It supports simulators, emulators and real devices simultaneously
- The testers can use the inspector for playback and record tool
- Supports JSON wire protocol
- Independent of mobile device means can be used in any mobile device
- Has an active google group
- Excellent support for android versions above 4.1
- With the use of simulators, appium speeds up ios app testing. This behavior makes the testers easier to understand and control the internal behavior of underneath ios devices but it does not allow multiple scripts in multiple simulators at a time
- The testing of the app below 4.2 android version is not allowed
- Support for hybrid app testing is limited
- Gestures support is not yet implemented like to access java library by double click
- No detailed documentation is there in the form of tutorials
- Image recognition is very poor we have to do this by using image handling techniques
- In Microsoft Windows, appium inspector is not supported
It is a language agnostic supports web driver application program interface, allows cross-platform tests. Applications are efficient, accurate, fast and free from bugs which save a hell lot of time and cost of the project. Keeping all this in mind learning appium will be worth it.
