Stubs-spy-manager

A module to help manage creating spies and stubs in jasmine utilising babel-plugin-rewire

Install:

npm i --save-dev @djforth/stubs-spy-manager

Set up

import SpyManager from '@djforth/stubs-spy-manager';
import MyModule from './path/to/my_module';

let spies_stubs = SpyManager(MyModule);

Adding spies:

spies_stubs([
  // Add foo spy with returnValue foo
  {
    spy: 'Foo'
    callback: 'foo'
  }
  // Add bar spy with callFake
  ,  {
    spy: 'Bar'
    callback: ()=>'foo'
  }
  // Add FooBar spy with return Spy
  ,  {
    spy: 'FooBar'
    returnSpy: 'foobar_return'
  }
  , {
    spy: 'foobar_return'
    callback: 'foobar_return'
  }
   // Add FooBarObj spy foo & bar methods
  ,  {
    spy: 'FooBarObj.foo'
    callback: 'foo'
  }
  , {
    spy: 'FooBarObj.bar'
    callback: 'bar'
  }
])

Adding stubs:

spies_stubs([
  // Add foo stub with returnValue foo
  {
    stub: 'Foo'
    callback: 'foo'
  }
  // Add bar stub with callFake
  ,  {
    stub: 'Bar'
    callback: ()=>'foo'
  }
  // Add FooBar stub with return Spy
  ,  {
    stub: 'FooBar'
    spy: 'foobar_return'
  }
  , {
    spy: 'foobar_return'
    callback: 'foobar_return'
  }
   // Add FooBarObj stub foo & bar methods
  ,  {
    stub: 'FooBarObj.foo'
    callback: 'foo'
  }
  , {
    stub: 'FooBarObj.bar'
    callback: 'bar'
  }
])

Make stubs & Spies

So you can add spies and stubs anywhere in your tests then you must call make before you test:

  describe('Create Spy', function() {
      let spy;
      beforeEach(()=>{
        spies_stubs.add([
          {
            spy: 'new_spy'
            , callback: 'foo'
          }
        ]);
        spies_stubs.make();
        spy = spies_stubs.get('new_spy');
        rv = spy();
      });

      it('should return foo', function() {
        expect(rv).toEqual('foo');
      });

      it('should call spy', function() {
        expect(spy).toHaveBeenCalled();
      });
    });

    describe('Create Spy Object', function() {
      let spy;
      beforeEach(()=>{
        spies_stubs.add([
          {
            spy: 'new_spy_obj.foo'
            , callback: 'foo'
          }
          , {
            spy: 'new_spy_obj.bar'
            , callback: 'bar'
          }
        ]);
        spies_stubs.make();
        spy = spies_stubs.get('new_spy_obj');
      });

      it('should return foo if foo called', function() {
        rv = spy.foo();
        expect(rv).toEqual('foo');
        expect(spies_stubs.get('new_spy_obj.foo')).toHaveBeenCalled();
      });

      it('should return bar if bar called', function() {
        rv = spy.bar();
        expect(rv).toEqual('bar');
        expect(spies_stubs.get('new_spy_obj.bar')).toHaveBeenCalled();
      });
    });

Get module

Basically a short hand for Module.GetDependency('myFunction');

 let myFunction = spies_stubs.getFn('myFunction');
