What could be the scariest words for an applicationdeveloper? ‘This application is pathetic,’ ‘This app has too many bugs and it’snot worth its name,’ or ‘It is a scam as this application doesn’t even functionproperly,’ etc.
would turn out to be a nightmare for an android applicationdeveloper. So, what is the requirement eventually? When an applicationis published on Google Play, it is required for it to be free of bugs andapparent technical glitches. A series of testing process needs to be carriedout before the application is broadcasted for user’s use. In order to safeguardthe testing effort, testing tool for Android App called Selendroid comes into thepicture. Selendroid is an automated test framework for multiple mobileapplication including native and hybrid android application as well as formobile web. SELENDROID & ITS FEATURES:One of the best frameworks for testing android apps,Selendroid is an open source automation framework that helps enable the userinterface of the android native, hybrid and mobile web app. It is based on theinstrumentation framework of the Android and the tests are simply written usingthe Selenium 2 client API.
To use Selendroid, you should have the knowledgebase of using Selenium. The automation framework is thus, used on real devicesand emulators and is integrated as a node into the Selenium Grid for scalingand parallel testing. The following are the features of Selendroid:1. It is an open source: Selendroid, as mentionedbefore, is an open source test mobile automation tool that has a built-inelement inspector that enables quick script development.
Although it onlysupports Java Language for scripting, the built-in inspector tool checks theuser interface element of the application during the test and in turn, helps indeveloping varied test cases for the developer. One of the most imperative featuresof the tool is that you are not required to modify the application during thetest as you are only required to install the binary file into your computer. Theonly requirement to be considered is that both, the test app as well as themobile app must be signed in with the same key during installation. 2. Supports all Android Versions: The most functionalfeature of Selendroid is that the testing tool can be easily used on multipledevices or simulators which act as the biggest advantage to the developers. Thisenables the developer to test the application with various android devices simultaneouslyso as to check its compatibility. From API 10 to API 19, Selendroid supportsall the new ANDROID API versions and so, the testing tool immediately recognizesthe new device automatically while testing without the need to restart or stopthe test in the middle.
It is an easier option to change the hardware devices(plug and unplug) during the test. 3. Easy to Implement: In order to automate thetesting tool, you needn’t modify the application under test as you only need toinstall the binary file (APK) on the computer. As mentioned above, theSelendroid has the Selendroid Inspector which is already embedded inside thetesting server which helps to inspect the current status of the application’s UI.It automatically displays the source HTML of a web view and also records theclick actions making it easy for it to be implemented. Selendroid supportsadvanced UI API in which human user actions such as swipe, touch, drag and dropetc. on an application can be simulated easily for more comprehensive testingand implementation. 4.
Effective while Executing Native Applications aswell as Cloud Based Applications: Since it is an open source, Selendroidsupports Selenium language script and is compatible with other web driverlanguages including Java, C#,Perl etc. While executing native apps and cloudbased apps, it verifies object recognition using the object properties andthus, makes it easier for the tester to implement the testing tool to achievethe desired output. 5. Works on Emulators and Real Devices: Since it isnot an easy task to validate each and every application that is being producedas it is a time-consuming effort and also, the android applications, mobile versionsetc. are not constant; the tester may find it difficult to define the scope ofthe entire test. Hence, to conquer this dependency on device, emulators arebeing created that provide real-time like environment to test the applicationand their versions. This testing is automated to ensure faster outcome usingscripting language. This feature is highly advantageous wherein thecompatibility of the testing app can be determined n various emulators andandroid devices simultaneously.
SETTING UP & TESTING USING SELENDROIDThe Selendroid tools workseffectively on Windows, Linux as well as Mac OS and to understand its process,let’s understand the process by using the tool on Window OS. In order to set upthe Selendroid testing tool for your application, following steps need to beimplemented:1. The foremost requirement is to create theenvironment for the testing tool and for that, you need to first, download and installJAVA SDK (minimum 1.6) software, the latest version of Android SDK, plug in atleast one real Android Device or AVD into the computer along with EclipseSoftware, Selendroid Standalone with dependencies, Selendroid Client andSelenium Client.
Now you need to setup the Android Home and Java Home on yourcomputer and the appropriate environment is created. 2. The next step is to download and launch theSelendroid Test App and Selendroid Standalone jar and give the run command onyour computer.
This is done with the help of the following command: java-jar selendroid-standalone-0.11.0-with-dependencies.jar -appselendroid-test-app-0.11.0.
apkOnce,you hit the run command, the Selendroid server will start on your system. This willidentify the Android target version, any emulator running and any hardwareAndroid device attached to the computer. The default port number of the server is 4444 which will startautomatically once you hit the run command on your computer for the testingtool to start functioning. There is also a possibility for you to change theport number by adding parameter to the command. 3.
The next step is to create a Java Project, buildSelendroid Standalone Libraries, Selenium Jars and JUnit libraries in the buildpath of your computer. You need to create a package under the Java Project andwrite the required code in the class created under the package. Once it isdone, all you need to do is run the class with testing run configuration. With the help of four components i.
e. Web Driver client, SelendroidServer, Android Driver App and Selendroid-stand alone, you can use the automatedtesting tool on any real device or emulators to test android native app, hybridapp as well as the web application. It is considered to be a very powerful toolin today’s era which is guided by e-commerce, mobile networking and onlinecommerce.
