The Selenium IDE is a browser extension can be used to record 'tests' belonging to one project (.side file).It is a convinient tool to record and replay interaction with a web page. Note, that the browser that will be openend by the Selenium IDE does share existing extensions, cookies and cache, but executing a script will open a browser without the cache (like a inkognito browser) . It is therefore recommended to clear the cache of a web page and disable extensions before using the Selenium IDE to record a test in order to not miss e.g. cookie banners that obstruct other elements. Clear page data Chrome , Clear page data Firefox .
After installing the browser extension, click on the Selenium IDE icon in your browser and follow the instructions to create a new project and within it a new test. The IDE will record every interaction on this page and store it in a .side file. The path to this project file and the specific test name have to be set in the configuration dialog of the Web Interaction Script Executor.
