Testing webapps end-to-end, with Selenium, for example
End-to-end testing refers to testing that attempts to simulate an actual human user interacting with your web application.
It is sometimes called end-to-end testing, because it tests the entire interaction with your web applications, from initial login, through a series of transactions, all the way to the goal that the user has. You might be simulating an entire user story, or sequence of stories.
It is often done using a technology called “Selenium”, which allows a programmer to automate a series of interactions with a web browser.
Sometimes that’s an actual web browser such as Firefox, and other times its a so-called “headless browser” where there is no “real” screen and rendering of the HTML to graphical visual elements, but just a simulation of that.
