I want to use project parameters at the project level by uploading a single CSV file that will run for all the test cases with a single click. basically, I want to use all the test cases for another site that is the same as mine only difference is the URL, username, and password. The rest of the site is the same, so I want to create parameters for URL, Username, and password and it will apply to all the test cases and the same test cases will run on another site.
You can create project parameters and use them as your application URL or anything else. In the recorder, you can simply choose these project parameters for any step that you want.
Regarding the CSV part, I didn’t understand your use case.
