When I test topics with the different Connections editors (CKEditor, Textbox.io and TinyMCE), I always used multiple users in my test environment, installed the editor selector ear and then gave each of the test users a different editor. That’s easy with the different j2ee roles, but I always had to use multiple browsers or sandboxes to see them next to each other.
During a support call with Tiny and HCL I learned, that you can switch the editor with a URL parameter. So no need to change the configuration or use the tinyeditorselector.ear.
