Let me share my experience… A Project….unknown technical issue…angry client....no documented requirement Test Cases: Well-designed and easy understandable steps executed to verify a particular feature of software. Test Scenario: A description of an objective a user might face when using the program. Test Scripts: A line-by-line description of all the actions and data needed to perform a test.

- 11. The main purposeof test case design techniques is to test the functionalities and features of the software with the help of effective test cases. The test case design techniques are broadly classified into three major categories. TEST CASE DESIGN TECHNIQUES www.edureka.co Specification-Based(Black- Box) Techniques Leverages external description of software to test cases: ➢ Technical specifications ➢ Design ➢ Client’s requirements Experienced-Based Techniques Highly dependent on tester’s experience: ➢ Skills ➢ Knowledge ➢ Expertise Structure-Based(White-Box) Techniques Test cases are designed based on the internal design: ➢ Software code ➢ Internal structure ➢ Design
