FAQ
Do I need Java experience?
Comfortable reading Java or C# helps; we provide starter branches in both. Pure manual testers should budget extra setup time.
Is this only for web?
Yes, browser automation only. Mobile stacks are out of scope for this module.
What if my employer blocks remote installs?
You need local admin or an approved container image; we cannot bypass corporate device policies.
