jasmine-spy-helpers

jasmine-spy-helpers adds some helper functions to Jasmine.

jasmine-spy-helpers is compatible with Jasmine 2.0+, but it will track with the current Jasmine version.

Utils Functions

• jasmine.spyAll(object)
  • Spy all functions of given object.
  • Spies are configured with callThrough

it('should spy all methods', function() {
  var obj = {
    id: 1,
    method1: function() {
    },
    method2: function() {
    }
  };

  jasmine.spyAll(obj);

  expect(obj.method1).not.toHaveBeenCalled();
  expect(obj.method2).not.toHaveBeenCalled();
});

• jasmine.spyIf(function)
  • Spy function if and only if function is not already a spy.
  • Spy is returned.

it('should spy method once', function() {
  var obj = {
    id: 1,
    method1: function() {
    },
    method2: function() {
    }
  };

  jasmine.spyIf(obj, 'method1');
  jasmine.spyIf(obj, 'method1');
});

• jasmine.spyAllExcept(object, [excepts])
  • Spy all functions of given object, excepts function names given in array (second arguments).
  • Spies are configured with callThrough

it('should spy selected method', function() {
  var obj = {
    id: 1,
    method1: function() {
    },
    method2: function() {
    }
  };

  jasmine.spyAllExcept(obj, 'method2');
});

• jasmine.spyEach(object, [only])
  • Spy all functions of given object that are specified in array as second arguments.
  • Spies are configured with callThrough

it('should spy selected method', function() {
  var obj = {
    id: 1,
    method1: function() {
    },
    method2: function() {
    },
    method3: function() {
    }
  };

  jasmine.spyEach(obj, ['method1', 'method2');
});

• jasmine.resetAll(object)
  • Reset all spy of given object.

it('should reset all methods', function() {
  var obj = {
    id: 1,
    method1: function() {
    },
    method2: function() {
    }
  };

  spyOn(obj, 'method1');
  spyOn(obj, 'method2');

  obj.method1();
  obj.method2();

  expect(obj.method1).toHaveBeenCalled();
  expect(obj.method2).toHaveBeenCalled();

  jasmine.resetAll(obj);

  expect(obj.method1).not.toHaveBeenCalled();
  expect(obj.method2).not.toHaveBeenCalled();
});

• jasmine.resetEach(object, [methods])
  • Reset each specified spies of given object.

it('should reset all methods', function() {
  var obj = {
    id: 1,
    method1: function() {
    },
    method2: function() {
    }
  };

  spyOn(obj, 'method1');
  spyOn(obj, 'method2');

  obj.method1();
  obj.method2();

  expect(obj.method1).toHaveBeenCalled();
  expect(obj.method2).toHaveBeenCalled();

  jasmine.resetEach(obj, ['method1']);

  expect(obj.method1).not.toHaveBeenCalled();
  expect(obj.method2).toHaveBeenCalled();
});

• jasmine.resetAllExcept(object, [methods])
  • Reset all spies of given object except specified methods.

it('should reset all methods', function() {
  var obj = {
    id: 1,
    method1: function() {
    },
    method2: function() {
    }
  };

  spyOn(obj, 'method1');
  spyOn(obj, 'method2');

  obj.method1();
  obj.method2();

  expect(obj.method1).toHaveBeenCalled();
  expect(obj.method2).toHaveBeenCalled();

  jasmine.resetAllExcept(obj, ['method1']);

  expect(obj.method1).toHaveBeenCalled();
  expect(obj.method2).not.toHaveBeenCalled();
});

A lot of code was borrowed from jasmine-utils, but I was looking to create just the spy helpers.
