  1. UnitTesting and ContinuousIntegration in context of IFDK referenceproduct

  2. About this course material • This material if for general training for Test Design and management • Material is more supportive in class room • Material will be updated during courses • FreeNest Portable Project Platform is used to demonstrate things only in practice. This is not limiting usage for material for other training environments (I hope ) Aboutmaterial

  3. TESTING LEVELS

  4. Unit/Module/Component Testing Product VALIDATION Customer/Business Requirements Acceptance Testing System Requirements Architecture& Design& Implementation System Testing Sub System Requirements Integration Testing Component Requirements Component / Unit Testing VERIFICATION Yläotsikko

  5. How to Test? What should be tested? How ?

  6. How to verify component implementation -Unit Testing -StaticAnalyze -DynamicAnalyze Yläotsikko

  7. What should be tested? Input ? Output?

  14. CodeCoverage An analysismethodthatdetermineswhichparts of the software havebeenexecuted (covered) by the testsuite and whichpartshavenotbeenexecuted, e.g. statementcoverage, decisioncoverageor conditioncoverage. http://en.wikipedia.org/wiki/Code_coverage http://www.atlassian.com/software/clover/ http://java.net/projects/hudson/lists/dev/archive/2009-03/message/235 http://en.wikipedia.org/wiki/Cyclomatic_complexity Yläotsikko

  15. CodeCoverage - Branchcoverage The percentage of branchesthathavebeen exercisedby a testsuite. 100% branchcoverage impliesboth 100% decisioncoverage and 100% statementcoverage. http://booster911.hubpages.com/hub/BranchDecisionTesting Yläotsikko

  16. CodeCoverage - Line coverage The percentage of branchesthathavebeen exercisedby a testsuite. 100% branchcoverage impliesboth 100% decisioncoverage and 100% statementcoverage. http://booster911.hubpages.com/hub/BranchDecisionTesting Yläotsikko

  19. Continuous Integration

  20. Continuous Integration One Commit Cycle Build Server Job 6. Report Change Trigger 3. Execute Build 2. 4. Report Source Code Repository Code Commit Build Report 1. CODER

  21. Analyzing & UnitTesting & CI

  22. Statical Analyze Dynamical Analyze Builder Make / Ant Gcc Javac Code Checker Unit Tester Complexity Analyze Integration Tester Source Code Interface Tester Heat Map
