What should a QA Engineer do to assure high quality?
When testing objectives are unclear (and often even if they are) I go to our generally accepted standards:
Have cases for the following types of tests and tag them accordingly
I also look at the test cases based on the test pyramid and the Agile Testing Quadrants and I look at what we have for unit and integrated tests and what should be added for UAT testing in the UI.
I also have to learn the business domain and cases so I know what's appropriate and useful to check for the business cases that should be tested
