You don't, you can test it all by hand. But it will take you much longer, especially after you've done, say, the 50th update to your program and had to retest every feature for the 50th time. Automated testing means you can type a command and wait while the PC does the work for you, usually only a matter of a few minutes to an hour - much less than the several hours it would take you by hand to do the very same tests. And the automated tool doesn't forget or use the wrong data with the wrong test etc. So its more consistent. And as you add new features you only need to add a few new tests and those features get tested each time too. When you are starting out it seems like you spend more time writing test cases than code 9and sometimes its even true!) but if your project survives for more than a few iterations its well worth the investment. And of course the corollary to that is that if its a one-off tool that is only for you and you'll "never use again" manual testing may be adequate. (But its surprising how many of those tools do get used again!) > i have tried some googling but the explanations are a bit crazy. Really? what kind of crazy? There are several Youtube videos that cover the reasons why, as well as the how to do it. They are mostly short too. And the reasons above are only scratching the surface, there are many more gains that apply to testing in general but are only practical if testing is automated. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
