Static analysis by tools
- 2. STATIC ANALYSIS BY TOOLS • Compiler can be considered a static analysis tool • Static analysis tools are typically used by developers before, and sometimes during, component and integration testing and by designers during software modeling • 1000 lines of code will contain many error which cannot be tested by dynamic testing • Tests the code hence improve quality, early detection of defects http://appium-selenium.com/
- 3. CODING STANDARDS • Classes name should start with capital letter • Methods name should start with small letter • Coding Standards save a lot of time • In Static analyzer tool we enter the coding standards • Developer can focus more on the program logic http://appium-selenium.com/
- 4. CODE METRICS • Comment frequency, complex coding, code size increasing • 20% code consists of 80% of defects • Cyclomatic complexity tells how much testing required for testing IF A, B=1, C=4 THEN IF B > C THEN A = B ELSE A = C ENDIF ENDIF Print A No. of decisions + 1 2 + 1 =3 http://appium-selenium.com/
- 5. CODE STRUCTURE • Control flow structure : dead code • Data flow structure : Variables never used • Data structure : information helps to identify data structures stack, queue allocation, deletion etc. for designing test cases http://appium-selenium.com/
