Set cookie domain prefixed with a dot

Current behavior:

The problem I am having is that the website I am testing is hosted on www.something.com. The website is using cookies to avoid showing a popup multiple times. The cookie the website adds has a domain “www.something.com”. I want to set this cookie when I start my test run so I don’t get the popup.

When I use setCookie and pass it a domain “www.something.com”, it actually adds a dot in the domain (.www.something.com). This causes the website to ignore this cookie and adds a duplicate cookie, without the dot before the domain.

Can I somehow force the setCookie to not alter my domain value?

Desired behavior:

The cookie domain to not be prefixed with a dot.

Steps to reproduce:

cy.setCookie('myCookie', 'true', { domain : 'www.something.com' })
cy.getCookie('myCookie').should('have.property', 'domain', 'www.something.com')

the assertion fails with “.www.something.com”

Hi @jennifer-shehane! Although this is indeed native browsers behavior there IS a possibility to set dot-less cookie by not specifying domain at all:

document.cookie = "test=Hello"

And this is what we can meet in real applications. By using cy.setCookie() we can’t mimic this behavior and this can lead to this:

First cookie was set by PHP itself while second one by Cypress. One of those cookies is definitely outdated and wrong and you never know which one will be used by application. Furthermore, real applications can have some technical subdomains which can also have their cookies set without leading dot.

Would it be possible to add some extra option to SetCookieOptions? Something like this:

cy.setCookie('test', 'value', {domain: 'example.com', domainExact: true})
cy.setCookie('test', 'value', {domain: 'api.example.com', domainExact: true})
cy.setCookie('test', 'value', {domain: 'static.example.com', domainExact: true})

And last but not least. I noticed that if my baseUrl is e.g. “docs.cypress.io” and I’m trying to cy.setCookie('test', 'value'); (without specifying domain) then cookie will be set to “.cypress.io” which is weird and not match browser behavior
