TestML is a software testing meta language for writing unit tests that can be shared among many programming languages. When writing modules in multiple languages, such as Perl 5 and Perl 6, TestML allows you to write tests once, reuse them in both modules, and allows for future reuse by module implementers in a variety of other languages. When porting an existing module from one language to another, modernizing the existing tests in TestML will ensure that both projects pass the same test suite.
This talk will show you how to use TestML, show off the cool new features added recently, and highlight the growing number of projects now using TestML.
