In many ways Perl's testing culture was the forerunner of TDD. CPAN Testers earned a lot of respect for making the Perl ecosystem stable.

this.

i remember silly java consultants rabbiting on about TDD and agile while dismissing oss.

meanwhile, the curation of both testing and documentation as well as overall code quality on CPAN was light years beyond the best corporate code i've ever seen.

i'd argue that perl (with CPAN) was the first internet native programming environment.
