tohavebeencalledwith multiple calls

Given the following code snippet, how would you create a Jasmine spyOn test to confirm that doSomething gets called when you run MyFunction? Note the syntax in Jasmine 2 is now Say I'm spying on a method like this: spyOn(util, "foo").andReturn(true); The function under test calls util.foo multiple times. I want to be able to call toHaveBeenCalledWith(something, anything).. Let's say I want to spy on a method .on(event, callback).All I care about is if the event is listened to rather than what the actual callback identity is. I have reviewed Jasmine's documentation of the toHaveBeenCalledWith matcher in order to understand whether it's possible to pass in a regular expression for an argument, if that argument is expected t… Mock functions allow you to test the links between code by erasing the actual implementation of a function, capturing calls to the function (and the parameters passed in those calls), capturing instances of constructor functions when instantiated with new, and allowing test-time configuration of return values.. The toHaveBeenCalledWith() matcher returns true and the spec passes Say I'm spying on a method like this: spyOn(util, "foo").andReturn(true); The function under test calls util.foo multiple times. I have an object that may be extended along my behavior under test, but I want to make sure that the original properties are still there.

Featured on Meta When using expect(...).toEqual({...}) it doesn't seem to match those complex objects. The follwing fails: expect( spy.mostRecentCall.args[ 0 ] ).toBe( {} ); Is there a way to use toHaveBeenCalledWith to check for identity? Using Jest, how can I check that an argument to a mocked function is a function? Is it possible to do this without writing a custom matcher? Is it possible to use Jasmine's toHaveBeenCalledWith matcher with a regular expression? Is it possible to have the spy return true the first time it's called,… Jasmine has built-in matchers toBe and toEqual.

function MyFunction(){var foo=new MyCoolObject();… The toHaveBeenCalledWith() matcher verifies whether the spied method has been called with the right argument(s). I put some console.log() in each API action so I know renderComponent() invoke both calls (CDM). Thanks. How do we clear the spy in a jasmine test suite programmatically? I expect to mockAxios be called 2 times but my test failed (it was called 1 time). var example={'foo':'bar', 'bar':'baz'} var result=extend… (2) The problem is that a function is an object and comparing objects in JavaScript will fail if they are not the same instance => 'test'!== => 'test' To solve this you can use mock.calls to check the parameters seperataly.

Not very many people know, that Jasmine provides you an ability to customize the result of equality check, which is internally used in toEqual, toHaveBeenCalledWith, and other matchers.

I know I can use the above, but then I might get into trouble if there are multiple calls. I've been reading through the Jasmine documentation and I've been struggling to understand what the Spies.and.stub method actually does.
