cypressioCypress cy.session(): Trading Test Isolation for Faster Authenticated Runs
Cypress cy.session() can eliminate redundant logins, but only if you disable testIsolation. Learn the trade-offs, version requirements, and how to verify the cache works.
Stop Sleeping in Your Cypress Tests: How Retry-ability Works
Fixed cy.wait() calls make Cypress suites slow and still flaky. Retry-ability, network aliases, and retrying assertions replace guesswork with deterministic waiting.
Using cy.intercept() to Stub Network Requests in Cypress: A Practical Guide
Stub XHR/fetch at the browser boundary with cy.intercept() to make UI tests deterministic — registering, verifying, and recovering from silent pass-through.
Choosing Between cy.intercept() and cy.request() in Cypress E2E Tests
Decide when to stub API calls with cy.intercept() or hit the real endpoint with cy.request() in Cypress. A practical guide compares speed, reliability, maintenance, and contract validation, then shows concrete test snippets and how to measure trade‑offs.
Deterministic Network Testing with Cypress cy.intercept()
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 Test Retries: A Practical Way to Tame Flaky E2E Tests Without Hiding Real Bugs
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.
Stubbing API Responses in Cypress with cy.intercept(): When to Fake It and When Not To
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.
Running Percy on Pull Requests: Catch Visual Regressions Early
Catch visual regressions early by running BrowserStack Percy on pull requests. Learn how to add a single snapshot to a Cypress test, handle dynamic content, and balance cost versus quality in your CI pipeline.
