I helped the QA department when I was a CO-OP with Panasonic innovation center, and it was mainly focused on QA testing and validation for enterprise kiosks. they were short-handed so I didn’t really get involved in everything. I only supported it part of my time, So I used to understand how the system should work and come up with a validation plane and write the document for test cases and scenarios. After that, I reviewed it with one of the senior engineers and if he approved it. I help to execute this plan and run the test for each scenario and document the outcome if it passes or fails with my comments. in this part is usually we find most of the glitches in the system if any. Then for practice, they would ask as to propose any correct of action if we can to fix the found issue.
