It's meant to make reading test results easier, giving you a visual summary of your test suite and letting you drill down into individual failures (which will hopefully make testing more likely to happen at your organization ;-).
It's based on Yuval Kogman's Test::TAP::HTMLMatrix which though useful, has a few limitations imposed on it by Test::Harness.
Over the past few years, after the evolution of the Test Anything Protocol (TAP), Andy Armstrong et. al. have produced a sorely-needed replacement for Test::Harness called TAP::Harness. It comes with a great little command-line utility called
provewhich makes it really easy to run your tests.
TAP::Formatter::HTMLyou can now produce your test reports in HTML:
% prove -m -Q --formatter=TAP::Formatter::HTML >output.html
Give it a whirl & let me know what you think!
