[tap-l] TAP tests

[Michael G Schwern]

By which I mean acceptance tests to ensure your TAP consumer is consuming
properly.  We don't have anything official, it sure would be nice if we did.
So I'm throwing this out as a project for someone (where someone does not
equal "Andy Armstrong" because he's doing too much already) to do.

A good place to start is the "sample-tests" directory in the TAP::Parser
distribution.  The expected results are in t/020-regression.t.  I'd suggest
the tests be encoded in YAMLish with the TAP and expected results in each
document.  For example...

---
name: simple
TAP: |
  1..1
  ok 1
results:
  overall:
    has_plan:      1
    planned_tests: 1
    passed:        1
    version:       12
    skipped:       []
    todo:          []
  lines:
     -
       type:          plan
       planned_tests: 1
     -
       type:          test
       result:        ok
       actual_result: ok
       directive:     ''
       description:   ''
...

These should be posted on the Wiki and probably eventually shipped with the
TAP module.
