Problems processing Cognito window for user sign on

[Neil Machin]

I have started developing a test suite for our system. I had no problem testing the two screen that did not require user sign on, or the welcome/sign on screen, but as soon as I try to process user sign on, for which we use 3rd party AWS Cognito things are failing.

Basically the code below allows sign on to our application, but when the Cognito window opens I can find any element on the screen and assert its value (all those lines in the code are working).

However any attempt to use send_keys or click to interact with the same elements fails, showing the error trace listed at the end.

The elements are not in an iframe or a separate window, are not hidden from view, and are not locked/disabled or any other reason that a human operator could not access them at any time..

Seems very odd to me that I can see and read elelements from the screen, but when I try to interact with the same ones I get an error that they are not reachable.

While this was waiting for approval I found out what the problem was.

It was down to me using Firefox to run the test. This worked for other screens in the application, but not for this one.

When I switched to using Chrome evertrhing ran normally.
