GEAR UP FOLKS, Selenium 4 is here!!!

What's new in Selenium 4:

  • Selenium 4 is fully W3C compliant: This means, in simple terms, that there is no need to install drivers for different types of browsers anymore.
    • To understand how this works, lets go back a little bit in time to the days of Selenium RC where the interaction with web browsers was done through injecting Javascript functions in the browser and use the injection javascript functions to drive the AUT. 
    • What happened afterwards starting from Selenium 2 was a bit different. Each browser provided its own APIs that supports the automation. Hence, you will find Chrome browser, Geko driver for firefox and similar drivers for other types of browsers. The new thing in Selenium 4 is that it is fully compliant with W3C which means that no need to install any external web drivers, CHEERS!!
  • Selenium IDE is back.
    •  After deprecating Selenium IDE somewhere back in August 2018, it is coming again in Selenium 4 with the enhanced features of being pluggable to any browser(not only Firefox)
    • The new IDE will rely purely on NodeJs, not the old HTML runner>
    • It supports parallel execution.
  • Selenium grid setup easier: Everyone recognize the pain setting up the Hub and Node, with Selenium 4, this pain is resolved by only setting up the server, which acts as a Hub and Node at the same time.

    Second video in the advanced JMeter topics, Many of us use JMeter for performance testing, while the tool offers plenty of wonderful resources and plugins, a point of order is required when the project grows large, you need a framework to organize things and to ease the maintenance mission, check this youtube video https://www.youtube.com/watch?v=8kLWRdjnopw This project describes how to create a reusable JMeter script that takes into consideration the following aspects: 1- Re-usability 2- Maintainability 3- Extension We have used the following components to achieve our target: 1- Simple controller 2- Transaction controller 3- Module controller 4- Test fragment You can find the code on Github https://github.com/agnasser56/JMeterA...
