How effective is it adding a logout command at the end of a test case?

Question

I am running a test suite (test1, test2, test3) in Cypress. I noticed when I run this suite for the first time, they all pass. On the next test run, they fail. It seems that it is failing because the data from test3 has not been removed from the cypress browser when test1 begins to run. Could this be a load issue or would adding a logout command at the end of each test case be the solution? Not sure what would be the solution for this.

Answer 1

It seems that it is failing because the data from test3 has not been removed from the cypress browser. First step is to find out where that data being stored ex: cookie, session storage or local storage? Once you found it, you can choose appropriate method to delete data. Incase you are interested in clearing all u can do something as below

beforeEach(() => {
 cy.window().then(win => win.sessionStorage.clear());
 cy.clearCookies();
 cy.clearLocalStorage();
 });

Make sure above syntax is correct from cypress.io.

Answer 2

Have you tried adding a step to clear the cookies?

Cypress.Commands.add('logout', () => {
    cy.clearCookies().then(() => {
        cy.getCookies().should('be.empty').visit('/')
    })
});
