The Test Anything Protocol (TAP), was originally Perl's simple text-based
interface between testing modules and test harnesses, but has since been
adopted by a large number of producers and consumers in many different
languages, which allows colorizing and summarizing test results.
The format is very simple:
TAP version 13
ok 1 - test description
not ok 2 - test description
---
message: 'Failure message'
severity: fail
expected: 123
actual: 456
...
ok 3 - test description # SKIP
1..3
The specification [1] is very brief, so the implementation has been
based on how typical consumers behave, especially when it comes to
the undefined diagnostics block.
