Imagine that you are head of testing department of a software house. In your department, there
are several testing staff who design testcases for different software modules. A module holds
some n number of lines of code and each test case may cover some of the code lines of the module.
For example, let our very simple module contains lines of code ie
n and we have k number of different test cases prepared for the testing the module. Table shows an example
line numbers covered by each of different example test cases.As the head of the testing department, you wish to minimize the number of applied test cases per module in order to save testing time. On the other hand, the selected minimum number of testcases among k alternatives are required to cover all the lines of module under test together in order to not to risk some of the module lines not being tested. In other words, the selected
minimum number of test cases should cover all the code lines of the module collectively. For example for the above problem instance, you have to select the test cases and that covers all the module lines together. In your solution, assume that each line of the module under test is covered by at least one test case.In order to solve the problem, you decide to develop a software tool that uses Transform &Conquer algorithm design technique. According to the approach, first you need to convert given
problem instance into an Integer Linear Programming ILP problem then solve the constructed ILP problem by using a backend solver namely IBMCplex Solver on the fly. Finally, display the obtained result in a meaningful way. See Figure below.Your homework submission should include the following pieces:
i A report that explains how you transform the test case selection problem into the ILP
problem. pts
ii Source code of your algorithm. In your code, do NOT hardcode the sample problem input
instance above but read the sample input either from screen or from a text file. pts Figure A simple architectural view for your test case selection software.
