Testing

Testing

1. program testing

   • goals
     • validation testing
       • success: operate as intended
     • defect testing
       • success: exposes a defect
   • uses
     • artificial data
   • reveal presence of errors not absence
   • results
     • errors, anomalies, information regarding non-functional attributes
   • V&V confidence
     • aim - fit for purpose
       • software purpose
       • user expectations
       • marketing environment
     • verification
     • validation
     • inspection vs testing
       • static vs dynamic

2. release testing

   • requirement based testing
   • performance testing

3. user testing

   • alpha testing
   • beta testing
   • acceptance testing
     • agile methods
     • define criteria, plan testing, derive tests , run tests, negotiate results, accept.reject

4. development testing

   • unit testing
     • object class testing
     • automated testing
     • test cases
     • testing strategies
       • partition testing
       • guideline-based testing
         • testing guidelines/sequences
   • component testing
     • components
     • interface testing
       • parameter interfaces data
       • shared memory interfaces
       • procedural interface
       • message passing interfaces
       • interface errors
         • interface misuse
         • interface misunderstanding
         • timing errors
   • system testing
     • component interactions
     • reusable components
     • use-case testing
   • policies
     • test all functions accessed through menus
     • test combination of these functions
     • test user input, all functions tested with correct & incorrect input
   • test-driven development
     • identify functionality, write test, run test, implement functionality
     • benefits
       • code coverage
       • regression testing
       • simplified debugging
       • system documentation
