  Week 12 : Assignment 12 Due date: 2022-10-19, 23:59 IST. Assignment not submitted 1 point State true or false: Regression testing is a white-box testing technique as it tests for the changes done to the code.   True.   False. 1 point Let  P P  be a program and let  P ′ P ′  be a modified version of  P P . Whendo we say that a particular test case  t t  is obsolete for  P ′ P ′ ? Test case  t t  is obsolete for  P ′ P ′  if it has an input that is not valid for  P ′ P ′ . Test case  t t  is obsolete for  P ′ P ′  if it does not produce an output on execution. 1 point State true or false: Testing for non-functional or quality requirements can be done at all the phases of software development.   True.   False. 1 point If a software application version  X X  released in the year 2007 can be used on version  Y Y  of the same application released in the year 2010, what does it indicate regarding its compatibility? The application  X X  is forward compatible. The application  X X  is backwa

  Week 11 : Assignment 11 Due date: 2022-10-12, 23:59 IST. Assignment not submitted 1 point State yes or no: Is concolic testing a white-box testing technique?   Yes.   No. 1 point Which of the following is true about concolic testing?   Concolic testing is used instead of symbolic testing when the latter fails.   Concolic testing keeps concrete state and symbolic state. 1 point What is the use of a SAT/SMT solver in symbolic testing?   SAT/SMT solvers are used to collect path constraints in symbolic testing.   SAT/SMT solvers are used to solve path constraints and get values that can be used as test inputs.   Constraint solvers are not useful in symbolic testing as not all path constraints can be collected and solved.   Constraint solvers on predicates always return true or false values which helps to decide the execution paths. 1 point State true or false: Symbolic execution can be used to detect non-termination in programs.   True.   False. 1 point Which of the following is a list o
