History & Origin of Selendroid
The Selenium is a collection of different tools and has contributions from different notable people. The long history of the selenium project has different stages with key individuals contributing immensely to the growth at different stages. Selenium was initially developed by Jason Huggins in 2004 while he was working as an Engineer in ThoughtsWork on a web application that requires frequent testing. He created the program using JavaScript, after using it he realized the shortcomings of manual testing and the need to curb monotony. He originally named the program JavaScriptTestRunner but after realizing the potential of the program, he made it an open-source program which he re-named Selenium Core.
What is Selendroid?
Selendroid is an open-source automation framework that drives off the UI of Android native, hybrid, and mobile web applications. It is based on the Android instrumentation framework. Furthermore, the tests are written using the API of the Selenium 2 client otherwise called as Selenium web driver. As a result, the existing Selenium framework is still reused by Selendroid. It also can be integrated with the selenium grid for parallel execution on multiple nodes.
Features of Selendroid are:
- Why use Selendroid?
- It is an open-source (free to use)
- Supports Selenium as a scripting language
- Supports web driver compatible languages such as Java, C#, Perl
- Supports all Android Versions
- Works both on an emulator as well as the real device
- Works on a native, hybrid, and web-based application
- It supports object recognition using object properties
- Easy to implement
Advantages of Selendroid
- Selendroid is completely compatible with JSON wire protocol and is selenium three-ready.
- Mobile testing using Selendroid does not require modifying the app that is to be tested for the automatic test procedure.
- Mobile web can be tested using the built-in web view app android driver.
- The framework applies the same concept to automate native or hybrid apps.
- Any UI element can be easily found using different types of locators in Selendroid.
- Selendroid supports gestures and advanced user interaction API.
- The framework automatically starts existing emulators.
- Full hot-plugging supports for hardware devices.
- Easy and complete integration into Selenium grid as a node, which facilitates scaling and parallel testing.
