Knock is a simplification of the Test Anything Protocol used by Perl and others.

Every test suite is a script that prints lines looking like:

ok ... for a passed test not ok ... for a failed test

... for diagnostics

Everything else is ignored. Scripts should exit with 0 when they ran all tests and non-0 when there was a fatal error.

Included implementations:

knock.h (GNU/C99) macros for Knock in C knock.rb Knock for Ruby knock.sh Knock for sh and bash knock.zsh Knock for zsh

Tools included are:

kn-sum print a summary of the Knock input given on stdin kn-agg print a summary of the Knock input, as Knock line kn-nice reformat Knock to make it easier scannable

For usage, see the test suite "test-all" in test/.

Why "Knock"? Think "knock on wood... tap tap". (Thanks to Eric Hollensbe for the name idea.)
