For example, you may want to run some tests against a real web page, create a PDF of it, or just inspect how the browser renders an URL. It is a cross-platform portable framework for testing web applications, without the need to use or learn a specific testing language. Sorry – I wasn’t too clear in my question.Oh I see, so you need to switch to a different window. Awesome!What we are going to do is to make some modifications to the existing code, so that we don’t need to open the browser’s developer tools manually and paste the generated JavaScript code, to fill in the web page fields.We’ll do that step directly, by using Selenium to open the browser and assign the field values, automatically.So, let’s add the following import statements to our existing Then, let’s create a new function called automateBrowser, which we can place just before the execute function.Teacher at One Month.

Luckily, we can manually start and stop the server ourselves, and it only requires a few changes to the script above.While there are only three lines of code that have changed, let’s talk about what’s going on in them.
