perl: Acceptance tests do not include parse errors

[mpkorstanje]

🤔 What's the problem you've observed?

Currently the error set of tokens is not included in the acceptance tests.

gherkin/perl/Makefile

Line 46 in 1cc2ef0

acceptance: .built $(TOKENS) $(ASTS) $(PICKLES) $(SOURCES) #$(ERRORS) ## Build acceptance test dir and compare results with reference

This is a problem because:

As of May 2016 Gherkin is implemented in 8 languages. This number is likely to increase to a dozen within a year or two. Very few programmers are intimate with all those languages. Therefore, in order to make it as easy as possible to refactor, fix bugs, add features and release packages it is essential that all implementations have a similar structure.

CONTRIBUTING.md - consistency between implementations

✨ Do you have a proposal for making it better?

Fix the acceptance tests to include the parse errors.

Cheers! No rush at all, it's been like this for a while.
