Keep in mind TDD wasn't really invented yet, so it's understandable. Also, CPAN had better libraries than pip did all the way up until I last used Perl in 2015. Ofc, it depends on what you're doing. My point is, there was a reason to use Perl once upon a time ago. The alternatives back then were PHP, C, C++ (the old bad kind), BASIC, assembly, FORTRAN, and others like Smalltalk. Seeing this, it's understandable why Java took the world by storm the same way Perl did.
