With the introduction of the agile methodology and transformation into the digital world, the software development lifecycle is changing rapidly and increasing the need for better software testing capabilities. And software testing is being forced to be reinvented every day due to the introduction of new technologies like artificial intelligence, virtualization, and predictive analysis.
Speed Curve

Ten years ago the network was the biggest problem when it came to making websites fast. Today, CPU is the main concern. This happened because networks got faster while JavaScript moved in the other direction growing 3x in size in the last six years. This growth is important because JavaScript consumes more CPU than all other browser activities combined.

Organisations maximising the advantages provided by microservices tend to be organisations which view microservices not just as a technical tool, but a sociotechnical tool.The way software systems are shaped determines the communication paths and the coupling between development teams. As microservice systems grow, the risks of sociotechnical coupling increase significantly.

Real User Monitoring (RUM) is the ability to measure the performance of your website/web application as seen by your end users.

Locators are the foundation of building your Selenium Script. With the use of locators, one can locate the element on the web page. Not only is locating an element important but making sure it’s fast and accurate is equally as important.
