Of path that one should test.Both 1 and 2Either 1 Or 2www.ramkumarsjava.comBoth 1 & 2www.ramkumarsjava.comIf Complexity = 10 then Minimum 10 cases will :Cover all the code.Test decision logicTest the interaction between code constructTest the UIwww.ramkumarsjava.comAll except 4www.ramkumarsjava.comCyclomatic Complexity is a metric s/w used to:Measure the complexity of the programIndicate the complexity of the SoftwareOnly 1Both 1 and 2

www.ramkumarsjava.comAns : 4www.ramkumarsjava.comCyclomatic Complexity was developed by:Thomas J. McCabe, Sr. In 1976Sir Ravindra Jadeja in 1967Sir Gabbar Singh in 1984Sir Asaram Bapu in 2014www.ramkumarsjava.comAns : u better knowwww.ramkumarsjava.comThe Complexity (M) is defined as :M = E N + 2PM = E N + PM = N E + 2PM = N P + 2Ewww.ramkumarsjava.comCyclomatic Complexity helps to :Measure no. Of linearly independent path in a prog module.It provides relative complexity of various design.Compute complexity early in life cycle.Guide the testing process by limiting the program logic during development.All of the above.

www.ramkumarsjava.comAns : 5www.ramkumarsjava.comM = 11 to 20 is ?Low Complexity High Complexity Medium Complexity Highly unstablewww.ramkumarsjava.comAns : 3www.ramkumarsjava.comCyclomatic Complexity help to :Redesign complex modulesAllow more time for building and testing complex modules.Assign more experienced personnel to the complex module.Execute complicated people in your life.1, 2, 3

www.ramkumarsjava.com Ans : Its obvious www.ramkumarsjava.comWhen the determination is made that the class method are complex then the action justified are:Re architect solution.Split chosen methods into smaller chunks.Generate detailed documentation.Undergo extra reviewsAll of the abovewww.ramkumarsjava.comAns : 5www.ramkumarsjava.comAdvantage of Cyclomatic Complexity is?Metric is directly related to maintainability and testabilty.It can be computed immediately in the development cycle.It warns the developer during the development itself where the code is complex.Measures the minimum effort for testing. www.ramkumarsjava.com Ans: All 4www.ramkumarsjava.comTools available to compute Complexity are?
