MisMatch Between Expected And Actual Images After Test Has Been Run. No Errors Were Generated

You're using the visualizer in your playback... and that does just a display of what was done during recording versus what was done during playback.   It's not actually a test to do a comparison so that's why you're not getting an error.

As for code "generated"... test complete doesn't "generate" code on playback... it plays back the code that was there.  If you look at your log, you see that, right before your screenshot, there's an indication that the letter "A" was entered into the text box... that should demonstrate what was there at the time of the test.
