- 32. Selenium RC The browser works accordingly Paul Hammant developed Selenium RC Selenium RC is a server written in Java RC makes provision for writing application tests in various programming languages like Java, C#, Perl, PHP, Python etc The RC server accepts commands from the user program and passes them to the browser as Selenium-Core JavaScript commands
- 33. Selenium RC RC Server Web browser injected with Selenium core • Consider a JavaScript program test.js used by google.com • The program can access pages within google.com like google.com/mail, google.com/login
- 34. Selenium RC RC Server Web browser injected with Selenium core • However, it cannot access elements of other domains like yahoo.com • Local copies of Selenium core and the web browser had to be installed so that they belonged to the same domain
- 35. Selenium RC RC Server Web browser injected with Selenium core This is called Same Origin Policy and Selenium RC was introduced to address this limitation. The server acts as a client configured HTTP proxy and "tricks" the browser into believing that Selenium Core and the web application being tested come from the same origin

- 55. Selenium suite of tools Selenium RC Selenium WebDriver Selenium Grid Selenium suite Selenium IDE Let’s learn about Selenium Grid
- 56. Selenium Grid Grid is exceptionally flexible and is integrated with other suite components for simultaneous execution Developed by Patrick Lightbody The main objective of Grid is to minimize test execution time Grid was designed to distribute commands to different machines simultaneously Selenium Grid allows the parallel execution of tests on different browsers and different operating systems
- 57. Selenium Grid The Grid consists of a hub connected to several nodes. It receives the test to be executed along with information about the operating system and browser to be run on
- 58. Selenium Grid The hub picks a node that conforms to the requirements (browser and platform) and passes the test to that node
- 59. Selenium Grid The node runs the browser and executes the selenium commands within it
- 60. Selenium Grid Limitations of Grid Limited scalability Cannot scale up or down on demand
- 61. Selenium Grid Limitations of Grid Limited scalability Cannot scale up or down on demand Static Since the nodes are pre- configured, making changes is a challenge
