11. Test Strategy – Types of Testing 1. Unit Testing It is a procedure used to validate that a particular module of source code is working properly. 2. Integration Testing Testing two or more modules or functions together with the intent of finding interface defects between the modules or functions. 3. Functional Testing Testing that ignores the internal mechanism of a system or component and focuses solely on the outputs generated in response to selected inputs and execution conditions . 4. System Testing Testing that attempts to discover defects that are properties of the entire system rather than of its individual components.

14. Template of Use Case

16. Extracting Scenarios from Use Cases Valid Valid Pass Valid Invalid Fail Valid Blank Fail Invalid Invalid Fail Invalid Blank Fail Invalid Valid Fail Blank Valid Fail Blank Invalid Fail Blank Blank Fail User Id Password Status

21. Error Guessing For example, in an example where one of the inputs is the date, a test engineer might try February 29,2000 or 9/9/99 Based on the theory that test cases can be developed based on experience of the Test Engineer
