Test Anything Protocol

TAP, the Test Anything Protocol, is a simple text-based interface
between testing modules in a test harness. It decouples the reporting
of errors from the presentation of the reports.

One of its major uses is for noise reduction; when you have a suite
of many tests, making them TAP producers and using a TAP consumer to
view them helps ensures that you will see everything you need to
notice and diagnose breakage without being distracted by a flood of
irrelevant success messages. It can assist other forms of analysis
and statistics-gathering as well.

TAP started life as part of the test harness for Perl but now has
implementations in C, C++, Python, PHP, Perl, Java, JavaScript, Go,
Rust, and others. Consumers and producers do not have to be written
in the same language to interoperate.

Here's what a TAP test stream looks like:

1..4
ok 1 - Input file opened
not ok 2 - First line of the input valid
ok 3 - Read the rest of the file
not ok 4 - Summarized correctly # TODO Not written yet
