M14 starter folder (zipped)you will complete the following 4 items using that project. you'll be submitting 4 documents for this assignment.1. validation testing - 25 points. develop an appropriate set of test data to fully validate the program against. note - you were not asked to ensure that the program didn't process a negative number of hot dogs previously, can you deal with that issue now? if you find any errors at all - not just in data validation, but in the valid execution of the program at all, you must fix them in the code and test again to validate that your changes worked. create to turn in, an appropriately named word document consisting ofa. the data sets you tested againstb. a brief written explanation of the results of your tests and what you had to fixc. screen shots of your good test data working.2. performance testing - 25 points. once you've validated the project, you'll do a benchmark 'performance' test. see the attached file, edit it appropriately, and submit your edited version for grading. 25 points. drone dogs part 4 benchmarkpreview the document3. user manual creation - 25 points. you will write and submit a user's manual for the dronedogs project given in this module (that is, it does not include the secondary order form) and submit it according to the instructions in the attached file. 25 points. drone dogs part 4 user manualpreview the document4. documentation of source code - 25 points. you will fully document (comment) the corrected visual basic source code with appropriate comments including: a. a brief explanation of the purpose of each module (sub) at the beginning of each sub. b. explanation of the purpose of each variable where it is declaredc. line by line, or at least section by section comments within the code, explaining what the line/section does. you'll turn in the document you created in item #! , the edited document from item #2, the users manual from item #3, and your documented course code listings (not the entire project folder, just the content of the .vb files) from item #4. a total of four files if you combine your code into one upload, more than that if you upload each .vb file separately. name the code listings as sdev140m14apply_dronedogs_xxx_lastn amefirstname (where xxx is the name of the code file, and using your name). for instance: sdev140m14apply_dronedogs_customerf orm_lastnamefirstname.
