This is the README file for Test.Simple, basic utilities for writing tests, by Michael G Schwern as ported to JavaScript by David Wheeler . This package also contains Test.Harness and Test.Harness.Browser. You can use the latter module to run all of your Test.Simple and Test.More tests in a single browser window, similar to how Perl's Test::Harness allows all tests in a package to be run with a single shell command. Please consult the documentation for how to start writing tests for your JavaScript code.
