Measure loading times of predefined divs with selenium webdriver
The program opens a website a defined number of times and looks out for specified divs, that are set from the called website. This project is used in UnityWebGL-LoadingTest to track the average time it takes until Start and Awake are called on Unity's side.
The website you want to track needs to have certain tracking structure. That is, a #tracking div, in which all #tracking-{name} values can be found. Inside #tracking-{name} there needs to be another .tracking-milliseconds entry that contains the number of milliseconds you want to pass there. Normally, you will set this to performance.now().
This gives a very high flexibility on what you want to track, since it can be easily triggered from the client, no matter in which environment you are.
