Partition the input domain space, identify representative test cases and create test suite. Questions:Task 5.1: Create a folder on your machine and name it with your IDTask5.11.Initialize this folder as a Git repository. 2.Download the provided specification documentinto the folder IDTask5.13.Read and understand the specification document.This specification is for calculating income tax.4.Open a new MS Word file and save it as partition.doc in the IDTask5.15.Trach *.java and MS Word document file.6.Identify the input domain space of the problem. 7.Partition the problemdomain space.8.Select a representative test case from each partitionand for each test case calculate manually the tax. Fill your results in the following table:IDTest caseTax (manual)Tax (program)Fail/Success1.2.In this task, use the first three columns.9.Identify boundary test cases.10.With each meaningful change made to the source code file, do the following:a.Save the file in MS Wordb.Stage the filec.Store the file in the Git repository.d.Show the status of your repository.11.Save partition.doc as a PDF file and compress the repository and upload at IDTask5.1link in the Lab course website.
