Task l: Present your understanding of testing concepts Subtask $1\mathrm{.}1.$ Present your understanding of effectiveness metrics and how they can be applied to evaluate random testing and partition testing. The description must cover P$-$measure, E$-$measure and F$-$measure. You are required to discuss the effectiveness of random testing and partition testing in testing a program with an input domain consisting of $3$ partitions of sizes $100,200,$ and $250.$Assume there are $3,5,$ and $2$ failure$-$causing inputs, respectively in these partitions. Demonstrate how the proportional sampling strategy works on the abovementioned example and discuss its outcome in terms of effectiveness. Subtask $1\mathrm{.}2.$ Present your understanding of metamorphie testing. Your description must cover at least: test oracle, untestable systems, the motivation and intuition, metamorphic relations $($MRs$),$ the process of metamorphic testing and some applications. You are required to provide your own examples with at least three metamorphic relations in your description. Subtask $1\mathrm{.}3.$ Present your understanding of the mutation testing. Your description must cover at least: the mutants, mutation operators, and how mutants are killed. You are also required to provide examples for a set of at least $5$ mutation operators of your choice which can be used to generate a set of $20$ mutants in total.Task $2$: Test a program of your choice.In this task, you are required to test a real$-$world program of your choice using metamorphic testing and evaluate your testing using mutation testing. You are required to propose and describe at least two metamorphic relations $($and at least five metamorphic test groups for each metamorphie relation$).$These metamorphic relations must be different to those given by you in Subtask $1\mathrm{.}2.$ You can freely choose any program, but make sure that i$)$ the selected program is implemented by somebody else other than yourself, it satisfies all metamorphic relations and metamorphic test groups defined by you, and itmust be available from a public repository in GitHub; $($ii$)$ the selected program must be written in either Python, Rust, Java, JavaScript, Ruby, C$/$C$+,$ C#$,$ Bash, R$,$ Go or MATLAB; and $($iii$)$ the selected program is neither too large and complex nor too simple so that you can generate at least $30$ non$-$equivalent mutants from the original program $($either manually or using a mutant generation tool$)$ for testing in this task. You are required to provide screenshots$)$ capturing your program being executed and discuss the findings with supporting data showing the effectiveness of MRs in this task. You are also required to provide a self$-$contained and complete description of the testing process and discussion of results in the report.
