Cypress provides retry abilities on assertion. You can resolve the waiting issue for the redirection URL with the below change
cy.url().should('contain', '/redirection-url')
OR
cy.url().should('eq', 'mysite.com/redirection-url')
Here should
assertion will wait till 4 seconds by default and retries cy.url()
You can change the default timeout by updating parameter in cypress.json
file
{
"defaultCommandTimeout": 30000
}
Hope this will solve your issue.

Selenium has always been the most preferred test automation framework for testing web applications. This open-source framework supports popular programming languages (e.g. Java, JavaScript, Python, C#, etc.), browsers, and operating systems. It can also be integrated with other test automation frameworks like JUnit, TestNG, PyTest, PyUnit, amongst others. As per the State of open source testing survey, Selenium is still the king for web automation testing, with 81% of organizations preferring it over other frameworks.
Cypress is a renowned Javascript-based open-source, easy-to-use end-to-end testing framework primarily used for testing web applications. Cypress is a relatively new player in the automation testing space and has been gaining much traction lately, as evidenced by the number of Forks (2.7K) and Stars (42.1K) for the project. LambdaTest’s Cypress Tutorial covers step-by-step guides that will help you learn from the basics till you run automation tests on LambdaTest.
You can elevate your expertise with end-to-end testing using the Cypress automation framework and stay one step ahead in your career by earning a Cypress certification. Check out our Cypress 101 Certification.
