Cypress Errors
10 common Cypress errors with verified solutions.
CypressError: cy.visit() failed
cy.visit() failed to load the target URL. The server may be unreachable, or the response status code indicates an error.
CypressError: Timed out retrying after 4000ms
A Cypress command timed out while retrying. Cypress automatically retries assertions until the timeout, then fails. The default is 4 seconds.
CypressError: Expected to find element but never found it
Cypress could not find any element matching the selector within the timeout period. The element may not exist, may have a different selector, or may not have been rendered yet.
CypressError: element has been detached from the DOM
The element that Cypress was interacting with was removed from the DOM and re-rendered. This is common in React/Vue/Angular apps where components re-render.
CypressError: cy.request() failed
cy.request() failed because the server returned an error, the connection was refused, or the request timed out.
AssertionError: expected true to equal false
A Chai assertion in Cypress failed because the actual value did not match the expected value. This is the most common test failure type.
CypressError: An uncaught error was detected outside of a test
The application under test threw an uncaught JavaScript error. Cypress catches these and fails the test to alert you of application bugs.
CypressError: cy.origin() — Visiting a cross-origin URL
Cypress cannot visit a different domain within the same test by default. Cross-origin navigation requires the cy.origin() command.
CypressError: A fixture file could not be found
cy.fixture() could not find the specified fixture file in the cypress/fixtures directory.
CypressError: Cypress does not support multiple tabs
Cypress cannot interact with multiple browser tabs. Links with target='_blank' will open in the same tab if visited directly.
