Course Outcomes: The student will be able to :

 Derive test cases for any given problem
 Compare the different testing techniques
 Classify the problem into suitable testing model
 Apply the appropriate technique for the design of flow graph.
 Create appropriate document for the software artifact.

Question Paper Pattern:

 The question paper will have ten questions.
 Each full Question consisting of 20 marks
 There will be 2 full questions (with a maximum of four sub questions) from each module.
 Each full question will have sub questions covering all the topics under a module.
 The students will have to answer 5 full questions, selecting one full question from each module.
