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.

Every company wants their release cycle to be driven in the fast lane. Agile and automation testing have been the primary tools in the arsenal of any web development team. Incorporating both in SDLC(Software Development Life Cycle), has empowered web testers and developers to collaborate better and deliver faster. It is only natural to assume that these methodologies have become lifelines for web professionals, allowing them to cope up with the ever-changing customer demands.
Innovation distinguishes between a leader and a follower.
If you’re reading this, it’s either because you’re curious about the factors that go into Laravel testing and how to implement them in your application or because you just want to improve your knowledge of Laravel testing.

Mobile devices and mobile applications – both are booming in the world today. The idea of having the power of a computer in your pocket is revolutionary. As per Statista, mobile accounts for more than half of the web traffic worldwide. Mobile devices (excluding tablets) contributed to 54.4 percent of global website traffic in the fourth quarter of 2021, increasing consistently over the past couple of years.
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.
