A variation on this that I have used is to read the input from stdin as usual but redirect stdin when you run the code: python test_input.py < testdata.txt That way I can use multiple sets of test data and run the tests using the different data sets. The test suite is then exercised by a simple shell script that runs against each test file in turn. I find that easier and more flexible than using a StringIO buffer. You can catch EOF errors in your test rig or write the tests to read a finite set of data and create the data to match. -- 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
