static testing basics - Coggle Diagram

- - - - provide assessment of quality of work product
      - identify defect as early as possible
      - find different types of defect
  - - - req defect
        
        inconsistency, contradiction
        omission, inaccuracy, redundancy
      - design defect
        
        inefficient algorithms/database structure
        high coupling (khớp nối), low cohesion (sự kết nối /i/)
      - coding defect
        
        variable with undefined values, variables is declared but
        never used, unreachable code, duplicate code
      - deviation from standard (lack of adherence to coding standard)
        sự tuân thủ /i/
      - incorrect interface specification (different unit of measurement used by the calling system than by the called system
      - security vulnerability (sự dễ bị tổn thương) (susceptibility to buffer overflows)
      - gaps of inaccuracies in test basis traceability of coverage
        (missing test for an acceptance criterion)
