PhantomJS enables developers to load, browse, and analyse web pages automatically by writing simple scripts. It's useful for testing web pages that work as expected, monitoring performance, extracting relevant content, simulating user behaviour, and producing automatic web page screen shots. PhantomJS saves developers from needing to visit large numbers of web pages just to check how they work.
Style and Approach
Rapid PhantomJS will help you to write your own PhantomJS scripts easily in order to perform various testing tasks.
You will begin with a detailed description of the main functionality to build up the base of advanced PhantomJS scripting. You will then move on to learn about the scripting for the four main use cases of PhantomJS, which covers rendering images from any website to avoid visual regression, monitoring network traffic to notice performance degradation, simulating user behavior, and checking the results of your unit testing suite automatically. This is where you will master popular frontend build tools such as make, npm scripting, Grunt, and gulp. These will be set up to help you automate your new developed PhantomJS scripts in any environment.
By the end of the course, you will be able to automate and optimize your workflow with the help of PhantomJS, which leads to higher productivity and products of higher quality.
