in thread Unit testing OS rich code

The interesting part isn't the if part. It's the expression.

If that's not worth testing, so be it—but I've fixed enough bugs in file-handling code that I don't assume that relative paths are correct just because they look like constant expressions.

    I would agree, if he was actually performing the file test:

    sub file_exists
{
        my ($filename) = @_;
        #return (-f $filename);
        return 1;       
}

    But once he's mocked that up along with rename which can perform differently on different platforms, and touch, which may well not exist on many machines, all that's left is can perl: a) iterate a hash and b) take the correct branch in the if statement.

    Which is a pointless exercise that serves only to achieve a "100% coverage" statistic. S'no wonder development gets ever more expensive while error rates remain constant.
