Developer is the best person to know/understand the dark corners after any development/enhancement of enterprise software, compared to QA technician.
Developer can assess the depth/breadth of production problems that can arise from such dark corners.
FOR Quality reasons(only) but not for cost cutting, my new employer does not maintain separate QA team and shifts the responsibility to developer(as better owner) to write/append/automate/validate test cases. So, all new test cases are append to existing test suite, as part of process.

2) Does it add value for a Quality product delivery, if QA team is formed that has ethical hacking skills? For software products that run on network
