<Pains of Testing>
- I never really learned how to write good unit tests in
bootcamp or college. I just follow patterns in my
codebase.
- It never feels like I have enough time whether I write
them before or after. Reality is, estimated time to
complete a ticket doesn’t often include much testing.

reduces time focused on syntax.

Autocompletion for Applitools Eyes

1. It’s not magic. GitHub Copilot
can’t read my mind, and it will not
always spit out perfectly well-
written, up-to-date code.
2. Copilot increases my confidence and
velocity as a programmer. Now, I have
to worry less about syntax.
