QA Engineer Characteristics 

A Quality Assurance Engineer is a specialist who functionally tests software at all development stages. Sometimes it happens to mistakenly believe that the terms Quality Assurance, Quality Control, and Testing are the same, but it is wrong. And here is the difference:

  • A Quality Assurance expert’s job is to set criteria, prevent errors, and choose the instruments to use. 
  • A Quality Control specialist analyzes test results, also identifies and removes any bugs. 
  • A Software Tester has to verify the compliance of the finished product. 

An experienced quality assurance engineer should be hands-on in several things, including understanding the software growth cycle, preparing text documentation, refining test scripts, and drawing technical specifications to address defects identified after testing.
