Finished: FAILURE
Pretty close! To debug that failure, we’ll need screenshots though.
As we’ll see, this error is due to a race condition, which means it’s not
always reproducible. You may see a different error, or none at all. In
any case, the tools below for taking screenshots and dealing with race
conditions will come in useful. Read on!
Taking Screenshots
To be able to debug unexpected failures that happen on a remote PC, it would be good
to see a picture of the screen at the moment of the failure, and maybe also a dump of
the HTML of the page. We can do that using some custom logic in our FT class
tear

.We have to do a bit of introspection of

, but this will work:
