Testing stdout output modules * Tong * 12-28-2006

Hi,

I want to use the Test.pm from the standard Perl distribution to test my
module, but the problem is that the output of my module is writing to
stdout. Do I have to use something else or there are workarounds?

thanks

what does that have to do with Test.pm? you need to find a way to grab
the output of your module and then test those results. you can use a
localized STDOUT in a scope and then call your module. you can write a
wrapper script to drive your module and call it with `` from the test
script. but having a module write directly to stdout is a poor
idea. either pass in a handle (you could default it to stdout) or have
the module just return the text and let its caller do the printing. by
printing directly you force the module to be used in only one way which
is not a good design.

and you should look into using Test::More or some other better version
of Test.pm which is rather limited.
