How To Install libtest-filename-perl on Ubuntu 18.04
Introduction
In this tutorial we learn how to install libtest-filename-perl on Ubuntu 18.04.
What is libtest-filename-perl
libtest-filename-perl is:
Many cross-platform test failures – particularly on Win32 – are due to hard-coded file paths being used in comparison tests.
my $file = get_file(); # returns “foo\bar.t”; is( $file, “foo/bar.t” ); # fails on Win32
Test::Filename provides some handy functions to convert all those path separators automatically so filename tests will just DWIM.
The alternative is to write your own utility subroutine and use it everywhere or just keep on littering your test code with calls to File::Spec – yuck!
is( $file, File::Spec->canonpath(“some/path”), “should pass” );
Since this module is so simple, you might not think it worth including as a dependency. After all, it’s not that hard to always remember to use File::Spec, Path::Tiny or some other file utility, right? But odds are that, at some point, you’ll be so busy writing tests that you’ll forget and hard-code a path in your haste to show what a clever programmer you are.
So just use this module and stop worrying about it. You’ll be happier and so will anyone trying to install your modules on Win32.
