As has been mentioned: expect(4).to eq(4) This is specifically testing the value that you’ve sent in as the parameter to the method. When you’re trying to test for raised errors when you do the same thing: expect(raise “fail!”).to raise_error Your argument is evaluated immediately and that exception will be thrown and your test will blow … Read more
Simply mark any method you need to fake as virtual (and not private). Then you will be able to create a fake that can override the method. If you use new Mock<Type> and you don’t have a parameterless constructor then you can pass the parameters as the arguments of the above call as it takes … Read more
I just want to point out that while most of the responders assumed these were unit tests, the question did not specify that they were. nUnit is a great tool that can be used for a variety of testing situations. I can see appropriate reasons for wanting to control test order. In those situations I … Read more
Solution 1: jest.spyOn(Component.methods, ‘METHOD_NAME’) You could use jest.spyOn to mock the component method before mounting: import MyComponent from ‘@/components/MyComponent.vue’ describe(‘MyComponent’, () => { it(‘click does something’, async () => { const mockMethod = jest.spyOn(MyComponent.methods, ‘doSomething’) await shallowMount(MyComponent).find(‘button’).trigger(‘click’) expect(mockMethod).toHaveBeenCalled() }) }) Solution 2: Move methods into separate file that could be mocked The official recommendation is … Read more
You’ve got two different Board instances, so your call to Assert.AreEqual will fail. Even if their entire contents appear to be the same, you’re comparing references, not the underlying values. You have to specify what makes two Board instances equal. You can do it in your test: Assert.AreEqual(expected.Rows.Count, actual.Rows.Count); Assert.AreEqual(expected.Rows[0].Cells[0], actual.Rows[0].Cells[0]); // Lots more tests … Read more
I started with Scott Hanselman’s MVCMockHelper, added a small class and made the modifications shown below to allow the controller to use Session normally and the unit test to verify the values that were set by the controller. /// <summary> /// A Class to allow simulation of SessionObject /// </summary> public class MockHttpSession : HttpSessionStateBase … Read more
Is it possible to mock a static method using Rhino.Mocks No, it is not possible. TypeMock can do this because it utilizes the CLR profiler to intercept and redirect calls. RhinoMocks, NMock, and Moq cannot do this because these libraries are simpler; they don’t use the CLR profiler APIs. They are simpler in that they … Read more
There are a lot of benefits: You get immediate feedback on if your code is working, so you can find bugs faster By seeing the test go from red to green, you know that you have both a working regression test, and working code You gain confidence to refactor existing code, which means you can … Read more
Consider: class MyClass { //Implementation public void Foo() {} } class SomethingYouWantToTest { public bool MyMethod(MyClass c) { //Code you want to test c.Foo(); } } Because MyMethod accepts only a MyClass, if you want to replace MyClass with a mock object in order to unit test, you can’t. Better is to use an interface: … Read more
Mock object replace mocked class entirely, returning recorded or default values. You can create mock out of “thin air”. This is what is mostly used during unit testing. When spying, you take an existing object and “replace” only some methods. This is useful when you have a huge class and only want to mock certain … Read more
