Alias seems to not store it's value

Current behavior

During the test I’m comparing two values

First one is stored as ‘backgroundImageDefault’ with following code

    cy.get(selectors.pageAddress)
      .prev()
      .invoke('css', 'backgroundImage')
      .as('backgroundImageDefault');

At this point the backgroundImageDefault has value https://host.com/smth/defaultImage.jpg.

Then I’m changing the image, the new image obviously has a new address, https://host.com/smth/changedImage.jpg.

    cy.get('@backgroundImageDefault').then((background) => {
      cy.get(selectors.pageAddress)
        .prev()
        .should('not.have.css', 'background-image', background);
    });

It fails becouse when comparing it seems that alias ‘backgroundImageDefault’ now has value of https://host.com/smth/changedImage.jpg instead of it’s assigned value of https://host.com/smth/defaultImage.jpg.

Desired behavior

Until I upgraded to 12.0.0/12.1.0 the test simply passed and the value stored in the backgroundImageDefault was correct.

I like A and B 😃

B is more explicit but A gives no work if someone is not using aliases to store values

I like A, would we probably default to { type: 'query' } and document that this is how it was always meant to work? I mean it’s a little more work for people depending on the value but speaking for my team, we can manage to be explicit in our tests that need a different default.

I think C would be confusing to change it on the get at least in my mind we focus more on when we store values, like if we wanted to do a .as("originalValue") and then later compare to a new value, sample usage:

cy.get("@originalUrl").then(url => {
    cy.url().as("newUrl").should("not.equal", url)
})
