Explain how testing a software product is different and in many ways harder than testing any other engineered product. Provide at least three specific supporting points in your post. Your response should be no less than 300 words long and should be put in your own words. Please avoid using one long paragraph for your post; take the time to organize your work for readability - you will lose points for not formatting your work as requested. Take care to cite your work when necessary, even if it is information from the text or other reading in the module.
