Replace flaky waits with deterministic network control using Cypress cy.intercept(): stub responses, synchronize with aliases, and modify requests to cover error and slow-network states.
Cypress retries can stabilize a flaky CI pipeline — or hide real bugs. Here's how to configure run-mode-only retries, pair them with assertion-driven waits, and keep flake visible.
cy.intercept() makes Cypress tests deterministic by stubbing or spying on HTTP requests — but heavy stubbing can drift from the real API. Here's how to use it well.
Learn how to eliminate flaky E2E tests by using cy.intercept() to stub network requests, manage API state, and synchronize your UI assertions with network behavior.
Cypress’s built-in command retries and timeout handling synchronize tests with application state, reducing explicit waits–but understanding its boundaries is key to reliable E2E suites.
Learn how to eliminate flaky tests in Cypress using cy.intercept() to stub network requests, handle asynchronous responses with aliases, and simulate server errors.
Learn how to replace real backend calls with controlled stubs in Cypress, ensuring fast, deterministic tests. Follow this step‑by‑step guide to set up cy.intercept, validate requests, and handle failures.
Move beyond arbitrary cy.wait() calls. Cypress cy.intercept() enables deterministic API mocking, latency simulation, and contract validation across e2e and component tests—with practical patterns for GraphQL, binary payloads, and early-request blind spots.
Replace real API calls with deterministic stubs in Cypress using cy.intercept(). Follow a clear workflow to define, trigger, and verify interceptions, simulate errors, and recover from common pitfalls.
