Test:

  t.test('first', t => {
    t.plan(1)
    t.pass('done!')

  t.end()

i get the same.

ah. here's the beautiful issue:

    "babel": "^5.8.29",

[jkrems]

@moimikey So the issue was that the actual app was using babel 6..?

[moimikey]

Babel-tap is using Babel 5.8. So I'm guessing this is the conflict of trying to pair it with a Babel 6 project.

[jkrems]

I have a version that is using babel 6 (#5). The bad news is that babel-node has a pretty hefty startup penalty and tap spawns a child per test file.

[moimikey]

@jkrems yeah that definitely stinks. i see what you mean now... for what it's worth, i've read that the delay can also increase due to duplicate dependencies. it won't get rid of the problem, but maybe decrease the wait time. npm dedupe

[jkrems]

Published babel-tap@5.0.0 which uses babel 6.

Works like a charm. Much appreciated @jkrems
