  1. Automated Unit Testing

  2. Test Driven Development and Code Coverage Agenda • Software testing levels • Manual unit testing • Unit Testing based on UT cases • Automated Unit Testing • Automated Unit Testing with CPPUnit

  3. Too many of Software Testing Levels

  4. How we test this function? Requirement : - Write a module to add an User to DataBase Business rule : - Email can not be duplicated - Email must be in valid form - UserName ‘s length must be > 8 - UserName can not be dupplicated - Password length must be > 8

  5. Creative Commons Attribution Share-alike Manual Unit Testing • Write code • Uploading the code to some place • Build it • Running the code manually (in many cases filling up forms etc step by step) • Check Log files, Database, External Services, Values of variable names, Output on the screen etc • If it does not work, repeat the above process

  6.

  9. Creative Commons Attribution Share-alike Automated Unit TestingFirst Step • Coding Process with Automated Unit Tests • Write code • Write one or more test cases script • Auto-compile and run • If tests fail -> make appropriate modifications • If tests pass -> repeat for next method

  11. Automated Unit Testing Common Tools • UT Tools for references: • Java: JUnit, J2MEUnit • C/C++: cppUnit • Python: pyUnit • Perl: PerlUnit • Visual Basic: vbUnit • C# .NET: Nunit,csUnit • Refferences: • http://www.testingfaqs.org/t-unit.html • www.junit.org • http://www.codeproject.com/gen/design/autp5.asp

  12. Automated Unit Testing Common Tools http://sourceforge.net/projects/cppunit/ http://www.nunit.org http://www.junit.org/

  13. Automated Unit Testing with CPPUnitWhat is CPPUnit? Milk ? Beer or Coffee? • CPPUnit– an open source test tool for C/C++ • Useful for development and regression • Leads to a design-for-test approach • Tests can be written in C/C++

  14. Automated Unit Testing with CPPUnitWhere to get CPPUnit? • Let’s go to website: http://downloads.sourceforge.net/cppunit/cppunit-1.12.1.tar.gz Yeahh, I got it
