VisualizaçõesCypress preserving cookies over for a complete test suite
I am testing that requires you to be logged in while performing tests. In order to stay logged in I am preserving Cookies during a test run.
I use a custom function:
Cypress.Commands.add('preserveAllCookiesOnce', () => {
Cypress.Cookies.defaults({
preserve: (cookie) => {
return true;
}
})
})
Also tried
beforeEach(function () {
Cypress.Cookies.preserveOnce('session', 'YII_CSRF_TOKEN');
})
(Double-checked the name of the cookies)
Now in this test case I have included two post requests after logging in. But after those two POST request tests I get a 403 error when trying to access the page again.
If you need more details, please let me know. I am trying to keep the code to the minimum needed to understand the problem:
import {Login} from "../../pages/login/Login";
describe('test POST/client validation', () => {
beforeEach(function () {
cy.preserveAllCookiesOnce()
})
it('log in', () => {
login.goToLoginPage()
login.loginCredentials(Cypress.env('userEmail'), Cypress.env('userPass'))
})
it('test some stuff', function () {
cy.visit(Cypress.env('url') + '/index.php?r=tc/tcSettings/index&language=de')
.....
})
it('send POST/client request with incorrect values', function () {
cy.request({
method: 'POST',
...
})
.then(response => {
expect(response.status).to.eq(400)
expect(response.body.fields).to.contain({stuff})
})
})
it('send POST/client request with correct values', function () {
cy.request({
...
})
.then(response => {
expect(response.status).to.eq(200)
})
})
it('go to clients page and assert created client', () => {
cy.visit(Cypress.env('url') + '/index.php?r=client/index&language=de')
})
})
It looks like preserving the cookies does not work through the POST tests. When I try to access the website in the last step I get a 403 status.
Usually I can run any number of it instances with the command cy.preserveAllCookiesOnce() so my guess it, that it might have to do with the POST requests in between

Is the cy.preserveAllCookiesOnce() a custom command that you created in your Cypress's project? Note that you should use Cypress.Cookies.preserveOnce() instead:
beforeEach(function () {
// before each test, we can automatically preserve the
// 'session_id' and 'remember_token' cookies. this means they
// will not be cleared before the NEXT test starts.
//
// the name of your cookies will likely be different
// this is an example
Cypress.Cookies.preserveOnce('session_id', 'remember_token');
})
To enable or disable cookie debugging, use Cypress.Cookies.debug().
// Cypress will now log in the console when
// cookies are set or removed
Cypress.Cookies.debug(true)
cy.setCookie('fakeCookie', '123ABC')
cy.clearCookie('fakeCookie')
cy.setCookie('fakeCookie', '123ABC')
cy.clearCookie('fakeCookie')
cy.setCookie('fakeCookie', '123ABC')

Ok, I have finally found the cause of the problem. It does have to do with Cookies, but I absolutely can't explain what causes it.
In the first step I login as an Admin user. I save the session cookies for this user and then proceed to do the POST requests.
Yet, in step 5 when I want to check the clients page, I am suddenly logged in as a non-Admin user (a 2nd test account that I have created to make tests with non-Admin permissions).
To summarize:
it('log in', () => {
//in this step I log in as Admin
})
it('test some stuff', function () {
//in this step I am still logged in as Admin
})
it('send POST/client request with incorrect values', function () {
//still logged in as Admin
})
it('send POST/client request with correct values', function () {
//suddenly log in changes to non-Admin account
})
it('go to clients page and assert created client', () => {
//logged in as non-Admin, therefor this test fails
})
})
I can not find any reason in my code why the log-in state changes in the POST test.
But even though I can not find the reason, I can now work around the problem by adding an extra step before step 5 that just logs out and back in as Admin user.
This is the code for the POST step that causes the login to change:
it('send POST/client request with incorrect values', function () {
cy.request({
method: 'POST',
url: Cypress.env('url') + '/service/clients',
headers: {
'API-KEY': api_key,
},
body: body1,
failOnStatusCode: false
})
.then(response => {
expect(response.status).to.eq(400)
expect(response.body.fields).to.contain({
"some stuff"
})
})
})
I see no reason why this request should change the state of my session tbh. Plus the login credentials for the non-Admin user are used nowhere inside this spec file
