Was going to reply this too. The idea of TAP was to allow tests to be streamed too. So in theory a producer could output/emit events of test results. And a consumer would be able to parse/interpret the results. Upon a number like 1..2, it would know that the test set is done. It gets more complicated with subtests, but that was part of TAP 13 I think, which wasn't formally released.
