How to Test that URL Should Not Include a String in Cypress

If you want to verify that your URL should not include a string in Cypress, you can use the should('not.contain') assertion with either a string or a regex:

cy.url().should('not.contain', '/home');
// You can also use a regex
cy.url().should('not.contain', /home/);

You can also use this against the previous URL. Let's say you are testing the navigation and you would like to verify the URL after navigating away from the page. This can be done with a then callback in the following way:

cy.visit('https://cypress.io');
cy.url().then(url => {
    cy.get('.login').click();
    cy.url().should('not.contain', url);

    // You can also check equality
    cy.url().should('not.eq', url);
});

In the then callback, now you have access to the previous URL that you can use against the current one. Want to learn Cypress from end to end? Check out my Cypress course on Educative where I cover everything:
