tap-merge

Merge TAP 13 streams.

Re-numbers tests and test plans to remove conflicts. The test plan (e.g. 1..5) line is emitted last. Can be used from the command line or as a module. Streams everything, so it can process concurrently with the TAP producers.

Only asserts, plans and the version header lines are parsed. Everything else is left alone, so extras like YAML blocks or subtests will work.

CLI usage

cat <(tapProducer1) <(tapProducer2) | tap-merge

or otherwise concatenate two TAP streams and feed them on stdin to tap-merge.

Module usage

var tapMerge = require("tap-merge");
process.stdin              // or any readable stream
    .pipe(tapMerge())
    .pipe(process.stdout); // or any writable stream

If you want to give it multiple streams one after the other, use a module like multistream.

Example

Input (two TAP streams, one after the other):

TAP version 13
1..3
# first test
ok 1 - yep
# second test
ok 2 - yep
# third test
ok 3 - yep

TAP version 13
1..2
not ok 1 - fail
ok 2 - just fine

Output (one TAP stream; conflicts resolved):

TAP version 13
# first test
ok 1 - yep
# second test
ok 2 - yep
# third test
ok 3 - yep

not ok 4 - fail
ok 5 - just fine
1..5

Limitations

Doesn't do validation. Provide valid input.
