Yahoo eliminated their test and quality assurance department. Instead developers are doing their own testing. Can they test sufficiently without QA resource?
(…) unit testing only catches programmer errors in code, unit testing does not detect failures in the application, which means if you have 100% code coverage, that does not mean a bug free application.
Testers can pair with developers to write better unit tests and developers can help testers with writing automated checks and also educate testers about the architecture of the application so that they can design good tests to find the areas most likely to break during system testing.
Testers can ensure developers follow best quality assurance practices and assist with technical and business test designs to help identify the most critical bugs before releasing software.
