- How selenium works

- Selenium web driver
— Browser Driver
— Browser application

In order to execute the test in the specific browser, we need to have all these above.

In short, we communicate to browser application through selenium web driver. Then selenium web driver will send those requests to the browser itself by browser driver.

That’s why we need to download the browser driver (chromedriver, coccocdriver)

Remember in order to work with coccoc, you need to rename coccocdriver to chromedriver.

But in short, Selenium WebDriver is a collection of open source APIs which are used to automate the testing of a web application.
