Jasmine Matchers

toHaveBeenCalledWithContext()

describe('#toHaveBeenCalledWithContext', function () {
  it('should work with context', function() {
    var context = {foo: 'bar'};
    var fn = jasmine.createSpy();

    fn.call(context);

    expect(fn).toHaveBeenCalledWithContext(context);
  });

  it('should work with context and parameters', function() {
    var context = {foo: 'bar'};
    var fn = jasmine.createSpy();

    fn.call(context, 'baz', 'quux');

    expect(fn).toHaveBeenCalledWithContext(context, 'baz', 'quux');
  });
});

toHaveBeenDone()

Read more about nock: https://github.com/nock/nock

var http = require('http');
var nock = require('nock');

describe('#toHaveBeenDone', function () {
  it('should work with nock expectation', function(done) {
    nock('http://example.org')
      .post('/rest/v1/foo')
      .reply(200, 'ok');

    var options = {
      hostname: 'example.org',
      path: '/rest/v1/foo'
    };

    http.request(options, function (res) {
      res.setEncoding('utf8');
      res.on('end', function () {
        expect(nock).toHaveBeenDone();
      });
    });
  });
});

Jasmine Spy#calls extensions

thisArgFor(index)

describe('#thisArgFor', function () {
  it('should work', function() {
    var context = {foo: 'bar'};
    var fn = jasmine.createSpy();

    fn.call(context);

    expect(fn.calls.thisArgFor(0)).toBe(context);
  });
});

at(index)

describe('#at', function () {
  it('should work', function() {
    var context1 = { foo: 'bar' };
    var context2 = { baz: 'quux' };
    var fn = jasmine.createSpy();

    fn.call(context1, 'a', 'b');
    fn.call(context2. 'c', 'd');

    expect(fn.calls.at(1).args).toEqual(['c', 'd']);
  });
});

Jasmine SpyStrategy extensions

resolveValue(value)

describe('#resolveValue', function () {
  it('should work', function(done) {
    var spy = jasmine.createSpy();

    spy.and.resolveValue('foo');

    spy.then(function (value) {
      expect(value).toBe('foo');
      done();
    });
  });
});

rejectValue(value)

describe('#rejectValue', function () {
  it('should work', function(done) {
    var spy = jasmine.createSpy();

    spy.and.rejectValue('bar');

    spy.catch(function (value) {
      expect(value).toBe('bar');
      done();
    });
  });
});

resolveValues(value1, value2)

describe('#resolveValues', function () {
  it('should work', function(done) {
    var spy = jasmine.createSpy();

    spy.and.resolveValues('foo', 'bar');

    Promise.all([
      spy(),
      spy()
    ]).then(function (values) {
      expect(values).toEqual(['foo', 'bar']);
      done();
    });
  });
});

rejectValues(value1, value2)

describe('#rejectValues', function () {
  it('should work', function(done) {
    var spy = jasmine.createSpy();

    spy.and.rejectValues('foo', 'bar');

    spy.catch(function (value1) {
      spy.catch(function (value2) {
        expect(value1).toBe('foo');
        expect(value2).toBe('bar');
        done();
      });
    });
  });
