Selenium Integrated Development Environment (IDE)
Selenium Integrated Development Environment (IDE)
Selenium is not just a single tool but a suite of software, each with a different approach to support automation testing. It comprises of four major components which include:
- Selenium Integrated Development Environment (IDE)
- Selenium Remote Control (Now Deprecated)
- WebDriver
- Selenium Grid
1.Selenium Integrated Development Environment (IDE)
Selenium IDE is implemented as Firefox extension which provides record and playback functionality on test scripts. It allows testers to export recorded scripts in many languages like HTML, Java, Ruby, RSpec, Python, C#, JUnit and TestNG. You can use these exported script in Selenium RC or Webdriver.
>Selenium IDE has limited scope and the generated test scripts are not very robust and portable.
2. Selenium Remote Control
Selenium RC (officially deprecated by selenium)allows testers to write automated web application UI test in any of the supported programming languages. It also involves an HTTP proxy server which enables the browser to believe that the web application being tested comes from the domain provided by proxy server.
4. Selenium Grid
Selenium Grid is also an important component of Selenium Suite which allows us to run our tests on different machines against different browsers in parallel. In simple words, we can run our tests simultaneously on different machines running different browsers and operating systems.
Selenium Grid follows the Hub-Node Architecture to achieve parallel execution of test scripts. The Hub is considered as master of the network and the other will be the nodes. Hub controls the execution of test scripts on various nodes of the network
