The owner will be notified if you click the button more than once. Therefore in the event that the test is closed, you're screwed. Also, don't completely cover the testing page (switch tabs, switch to another window that is maximized or covers the testing page, switch desktops, minimize the testing page, etc.) as if that happens, the test is deleted and I have no way of circumventing that happening via this method. Other than academic honesty, you have pretty much nothing else to worry about. Just use splitscreen.
Step 1: READ ABOVE FIRST
Step 1.5 use this fake google form to test it.
Get to the view-source: page (add view-source: to the beginning of the URL of the form.) it should look like the image below
Step 2: Press CRTL A then CRTL C
Step 3: Copy this google sheet
Step 4: Click hacker
Step 5: Paste in all of your code from before DO NOT CLICK DO YOUR THING YET
Step 6: Open up google.com in a new window and splitscreen it and the form cracker
Step 7: Click the button, now that it is opened you must never fully cover the testing window. At most you are able to split screen it. Enjoy!
