Lately I need to test many small utilities written in various languages. For the most simple cases I just need to run the utilities with a set of input and check if the output is the same as expected.
For this it is enough to run system "path/to/utitlity < in.txt > out.txt 2> err.txt" and then compare them to the expected.out and expected.err To facilitate this I generate the input and the expected output files and put them next to the utility: path/to/utility path/to/utility.out path/to/utility.err path/to/utility.in In case I need to test the same utility with various inputs I keep path/to/utility path/to/utility.2.out path/to/utility.2.err path/to/utility.2.in <http://utility.in> Sometimes these utilities need to be executed with some other tool that even needs parameters. In such cases I use: system "pat/to/interpreter param param path/to/utitlity < in.txt > out.txt 2> err.txt" In most cases all the utilities in one package need to be executed the same way. I wonder if there are modules out there that already do this? I could not find any that would fit my needs. Gabor
