    testdouble-chai

    This is a tiny library that adds .called and .calledWith assertions to chai for use with testdouble.js. These assertions can be used as syntactic sugar over the testdouble.verify function. Here are some examples:

    Use

    it("can tell you if a testdouble object was called", function() {
      var td = testdouble.function();
      td();
      expect(td).to.have.been.called;  // instead of `verify(td)`!
    });

    or with arguments:

    it("can tell you if a testdouble object was called a certain way", function() {
      var td = testdouble.function();
      td("hi");
      expect(td).to.have.been.calledWith("hi");  // instead of `verify(td("hi"))`!
    });

    Setup

    After installing the library with npm install --save-dev testdouble-chai, here's how to get chai to know about testdouble-chai:

    // at the top of a test file or in a test helper
    var td = require("testdouble");
    var chai = require("chai");
    var tdChai = require("testdouble-chai");
    chai.use(tdChai(td)); // make sure to call tdChai with td to inject the dependency

    And you should be good to go! Check out test/testdouble-chai_test.js for an exhaustive description of how this library behaves.

    Install
