Sinon has a nice API for handling multiple calls (stub.onCall(n);) to the same stubbed method. Example from stub api doc: “test should stub method differently on consecutive calls”: function () { var callback = sinon.stub(); callback.onCall(0).returns(1); callback.onCall(1).returns(2); callback.returns(3); callback(); // Returns 1 callback(); // Returns 2 callback(); // All following calls return 3 } You …
Edit: I just reread your question and realized I didn’t quite answer it. Leaving my original answer because it’s related, but here’s your specific answer: The reason you don’t need a double is because you’re stubbing class methods, rather than instance methods. double is only useful for dealing with instances of the class, not the …
I assume you are referring to the terminology as introduced by Meszaros. Martin Fowler does also mentions them regularly. I think he explains the difference pretty well in that article. Nevertheless, I’ll try again in my own words 🙂 A Fake is closer to a real-world implementation than a stub. Stubs contain basically hard-coded responses …
PHPUnit used to support two ways of creating test doubles out of the box. Next to the legacy PHPUnit mocking framework we could choose prophecy as well. Prophecy support was removed in PHPUnit 9, but it can be added back by installing phpspec/prophecy-phpunit. PHPUnit Mocking Framework The createMock method is used to create three mostly …
This is because source code is not found in SDK. To see the source code, you need to download source for Android SDK, so Android studio can display the respective code.
Type stubs are sometimes packaged directly with the library. Otherwise there can be some external libraries to provide them. Numpy Starting with numpy 1.20 type stubs will be included in numpy. See this changelog and this PR adding them Before that they could added with the library https://github.com/numpy/numpy-stubs Pandas and Matplotlib There is no official …
You can overwrite some previous mocking by: expect(RestClient).to receive(:delete).and_call_original Or if it is wasn’t any kind of expectation, just a simple stub: allow(RestClient).to receive(:delete).and_call_original Remember there exists also expect_any_instance_of and allow_any_instance_of.
I suspect you want the useFakeTimers function: var now = new Date(); var clock = sinon.useFakeTimers(now.getTime()); //assertions clock.restore(); This is plain JS. A working TypeScript/JavaScript example: var now = new Date(); beforeEach(() => { sandbox = sinon.sandbox.create(); clock = sinon.useFakeTimers(now.getTime()); }); afterEach(() => { sandbox.restore(); clock.restore(); });
# Create a mock object book = MiniTest::Mock.new # Set the mock to expect :title, return “War and Piece” # (note that unless we call book.verify, minitest will # not check that :title was called) book.expect :title, “War and Piece” # Stub Book.new to return the mock object # (only within the scope of the …
You can stub a method to return different values each time it’s called; allow(@family).to receive(:location).and_return(‘first’, ‘second’, ‘other’) So the first time you call @family.location it will return ‘first’, the second time it will return ‘second’, and all subsequent times you call it, it will return ‘other’.
