Please refer to my code in the image provided to answer the following: Task $2$: Testing and documentation Consider the software development lifecycle and the importance of the testing phase. Once the development of your application is complete, you must carry out an extensive evaluation of the completed software. Part A: Test plan Once you have finished building the application, complete the following tasks. $1.$ Create a test plan with at least eight test items. The plan should be presented as a table in a Word document. Give your table an informative title. $2.$ The test plan should expand on the user acceptance testing and cover all requirements and acceptance criteria given in the case study. $3.$ At least three of your tests should involve testing that the calculations are giving accurate results. Set up your table as follows: Test Item, Expected results, Actual output, Actions required $1.$ Carry out a series of extensive user tests as according to the test items in your table. $2.$ Complete the columns for $$Actual output$$ and $$Actions required$$ for each test item. Part B: Applying the steps in the software development lifecycle Describe the steps you took in the software development process to ensure the client gets a viable product. Your descriptions should be easy to understand by the client and must cover these steps. $$ Requirement analysis: Describe what you did during this stage. $$ Design: Outline the key decisions you made. $$ Implementation: Explain how you put the plan into action, highlighting key decisions. $$ Testing: Discuss the tests you carried out and what you learned from them. Highlight the key decisions. Remember to do the following. $$ Keep descriptions brief and clear. $$ Explain how you have made the software easy to use. You might also want to mention user testing results. $$ Comment on benefits to the client. Keep the document under a page so the client can quickly understand the process. You do not need to talk about the evolution stage.
