stream-output
Get the result of stream output for your tests
There's no way this doesn't already exist, but I can't find what I'm looking for on npm.
I use transform streams for flow control/validation/mutation. I needed a clean way to run assertions on the end result during unit tests.
var output = require('stream-output/obj'); describe('Testing a set of transforms', function () { it('Does some shiz', function (done) { var test = function (data) { expect(data).to.have.deep.property('foo','bar'); done(); } SomeObjModeStream.pipe(someTransform).pipe(output(test)); }});
