9.2.3 Test Anything Protocol Extensions

• Home TAP, the Test Anything Protocol, is a simple text-based interface between testing modules in a test harness. TAP started life as part of the test harness for Perl but now has implementations in C, C++, Python, PHP, Perl, Java, JavaScript, and others.

  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
  

• Wiki The Test Anything Protocol extension exports 2 functions, write-tap and write-tap-to-file. These functions write a test results database using the TAP format.
