Test with Jest (JavaScript)

-2

I cannot execute the following test, what is the problem?

test('3 - shorthand syntax', function () {

    const name = 'Myamoto';

    const age = 32;

    const samurai = { name, age };

    expect(samurai).toEqual(age: 32, name: "Myamoto");

  });

.toEqual(age: 32, name: "Myamoto"); is invalid syntax... an argument list is not an object...

I can do: expect(samurai).toEqual(samurai); but I guess that it is not the way to pass an object?

You might consider figuring out basic JS syntax rules before diving into Jest, might be a bit easier

The problem is that you should pass and object to the toEqual() method, to compare to the Object that you've created.

expect(samurai).toEqual({age: 32, name: "Myamoto"});

– Alejandro

No. the toEqual() method compares the data passed to expect(), and see if they're equivalent. In this case, the both should be of the type Object, because the first is an object.

@Alejandro, that's not the right way to use jest. You should pass the samurai to a function, and pass the function call to the expect(), like expect(myFunc(samurai)).toEqual({age: 32, name: "Myamoto"});. Then, jest will compare if the result of your function is equivalent to what it should be.
