cli

if test/*.js represents a set of files exporting tests,

runs these tests using built-in assert and default reporter with:

pull-test test/*.js

api

test = require('pull-test')

test(tests)

runs tests using built-in assert and default reporter.

testSource = test.from(tests)

creates a source pull stream of test objects,

from any of the following format of tests:

function testTheThing (assert, cb) {
  assert(true), cb()
}

{
  ['test the thing']: function (assert, cb) {
    assert(true), cb()
  }
}

[{
  name: 'test the thing',
  test: function (assert, cb) {
    assert(true), cb()
  }
}]

through = test.Tester(options)

creates a through pull stream,

which expects to receive test objects with shape:

• name: name of the test
• test: function which receives (assert, cb). assert is the same as the node core assert module and automatically collects errors. cb is to be called when the test is done, or the test runner has errored (it will close the stream with the error).

and will return test result objects with shape:

• name: name of test
• assertions: array of assertions results from running test. either true if assertion passed or an instance of assert.AssertionError if assertion failed.
• duration: number of microseconds that test took to run

sink = test.Reporter(options)

creates a sink pull stream,

which receives test result objects and logs to the console.
