The same origin policy will only allow randomScript. However, it cannot access pages from different sites such as yahoo. This is the reason why prior to Selenium RC, testers needed to install local copies of both Selenium Core a JavaScript program and the web server containing the web application being tested so they would belong to the same domain. Unfortunately; testers using Selenium Core had to install the whole application under test and the web server on their own local computers because of the restrictions imposed by the same origin policy.
This system became known as the Selenium Remote Control or Selenium 1. Selenium Grid was developed by Patrick Lightbody to address the need of minimizing test execution times as much as possible. Shinya Kasatani of Japan created Selenium IDE , a Firefox extension that can automate the browser through a record-and-playback feature.
He came up with this idea to further increase the speed in creating test cases. Simon Stewart created WebDriver circa when browsers and web applications were becoming more powerful and more restrictive with JavaScript programs like Selenium Core. It was the first cross-platform testing framework that could control the browser from the OS level.
Currently, Selenium RC is still being developed but only in maintenance mode. The Name Selenium came from a joke which Jason cracked once to his team.
Since Selenium is a well-known antidote for Mercury poisoning, Jason suggested that name and his teammates took it. So that is how we got to call this framework up to the present. It is a Firefox plugin that you can install as easily as you can with other plugins. However, because of its simplicity, Selenium IDE should only be used as a prototyping tool. If you want to create more advanced test cases, you will need to use either Selenium RC or WebDriver.
Selenium RC was the flagship testing framework of the whole Selenium project for a long time. This is the first automated web testing tool that allowed users to use a programming language they prefer. As of version 2. It controls the browser by directly communicating with it.
Selenium Grid is a tool used together with Selenium RC to run parallel tests across different machines and different browsers all at the same time. Parallel execution means running multiple tests at once. Microsoft Edge version HtmlUnit 2. Quick Test Professional QTP is a proprietary automated testing tool previously owned by the company Mercury Interactive before it was acquired by Hewlett-Packard in When any browser Driver receives any command it will execute on that respective browser and send back the HTTP Response.
Drivers are nothing but specific to each browser used for a secure connection. All these browser drivers work directly on the top of OS which makes it faster than traditional Selenium RC.
How does selenium interact with the Web browser? Selenium Automation Testing Testing Tools. Adiya Dua. Previous Page Print Page. This is where the interaction with elements takes place in any operation. Testers and developers manually interact with the application elements to perform testing or a transaction to ensure the quality of the applications. The entire process can be automated with the Selenium WebDriver architecture.
With this architecture, the browser-specific driver's framework can take commands and HTTP requests to the HTTP server and interact with real browsers. Real browsers receive the requests from their browser driver and operate on the application elements according to the request. The browser responds to its browser driver with the operation's output. Then, the browser driver returns the output details to the client through the same channel.
The process will continue as follows:. Chicago, Illinois South Wacker Dr. Toronto, Canada 1 St. Selenium WebDriver Architecture From a functional perspective, WebDriver is a public interface that defines the reference variable driver of interface types.
Browser Drivers Each browser has a specific browser driver.
