Unit testing for grammars. Because testing is important.
No dependencies, except Test
which is a Rakudo core library, so the usual
zef install Test::Grammar
.
Copied from the source, version there is the single source of truth:
use Test::Grammar; parses-ok Test-Grammar,"num", 3, "33 parses OK"; my $test-output = q:to/EOC/; ok 1 - bailout parses OK ok 2 - «bailout» extracts token 1..2 EOC has-tokens Test-Grammar, "test", <nok num description>, $test-output, "Complete tests"; token-is Test-Grammar,"bailout", "explanation", "Bail out! FOOBAR", "FOOBAR", "«bailout» extracts token"; for <foo bar b3> { parses-nok Test-Grammar,"num", $_, "$_ not parsed"; }
There are very nice testing libraries out there:
