How Do I Assert Against Objects With Spies In Cypress?

I am using Cypress spies to test client-side analytics. My intent in this test is to confirm that identify has been called like so: identify('myemail@email.com', { groupId: 1002,

Solution 1:

I've solved the problem in the OP title. Wrapping the analytics method in a spy was another problem, but I've updated the snippet in OP to reflect how I fixed that (i.e., changing sleep interval to 1ms).

You can assert on the object in a spy call's args using the callback signature of cy.should:

const idProps = {
      groupId: 1002,
      groupName: "myGroup",
      someProp: 1,
      anotherProp: 2
    };

cy.get("@identify").should(a => {
      expect(a).to.be.calledWith("myemail@email.com");
      // pardon the property index-ref style, using typescript and i'm lazyconst spy = a["getCalls"](); 
      const { args } = spy[0];
      expect(args[1]).to.deep.equal(idProps);
    });
