এক নজরে

Cypress is a JavaScript-based E2E testing framework running directly in the browser with automatic waiting, time-travel debugging, and network stubbing. Covers L1 (basic commands, assertions) → L2 (custom commands, cy.intercept, page objects) → L3 (component testing, CI parallelization, visual testing). Career impact: +$18k-$30k. Learning: 2 months to proficiency. Lost market share to Playwright 2024-2026; strong in component testing + Dashboard analytics.

Cypress কী

Cypress is a JavaScript-native E2E testing framework running directly in the browser (using Electron or Chrome), providing automatic waiting, time-travel debugging, network stubbing, and real-time code reload. Unlike Selenium (language-agnostic but slow) or Puppeteer (headless-only), Cypress runs in the actual browser context, you see what the user sees, click what they click, and debug what they experience. In 2026, Cypress competes with Playwright (losing market share, Playwright is faster and multiplatform) but still holds strong in component testing and enterprise legacy systems. Career impact: +$18-30k for E2E testing fluency, but Playwright dominance in greenfield projects means learning both is pragmatic. Cypress is best used for critical user journeys (signup→payment, core workflow), not for exhaustive testing of every form validation or edge case (unit tests do that better). The sweet spot: integration layer (user interacts, system responds).

❓ প্রায়শই জিজ্ঞাসিত প্রশ্ন

Cypress vs Playwright 2026, which should I learn?

Playwright dominates new projects (multiplatform, faster, mobile testing). Cypress holds enterprise legacy (500+ Dashboard subscriptions, rich plugin ecosystem, time-travel replays). If greenfield: Playwright. If maintaining Cypress codebases: both. Cypress 13+ parallelization closed gap but DevOps cost favors Playwright.

Why does my test wait forever on cy.intercept()?

cy.intercept() stubs network, if route never fires, test hangs. Always add timeout: cy.intercept({...}, {times: 1}).as('api'); cy.get('#btn').click(); cy.wait('@api', {timeout: 3000}). Test against stubs in CI, not live APIs.

Can Cypress test mobile apps?

No native mobile. Cypress runs in desktop browser. For React Native: Detox or Appium. Viewport emulation ≠ mobile testing (no real touch, no real network). Use BrowserStack for real device E2E if mobile is critical.

How much does Cypress Dashboard cost vs GitHub Actions?

GitHub Actions: free (limited parallelization). Cypress Dashboard: $499-$2500/mo (unlimited parallelization, analytics, replay videos). For small teams: run on GH Actions + Mochawesome reports. Enterprise: Dashboard ROI > $20k/yr in faster CI feedback.

Should I E2E test everything or just critical flows?

Critical only: signup→payment, core workflow. Skip: form validation (unit test), style regressions (visual tests). E2E = slow + fragile if over-used. Pyramid: 70% unit, 20% integration, 10% E2E. Cypress best for integration layer.

Why is my CI 5x slower than local Cypress runs?

CI lacks GPU + parallel execution disabled by default. Enable parallelization: `cypress run --parallel --record`. BrowserStack or Cypress Dashboard required for true parallelization. Expect 3-5x speedup but higher cost.

Cypress failing in headless CI but passing locally, how to debug?

Headless Electron differs from headed Chrome. Run locally: `cypress run --browser chrome --headless`. Check timing: add `cy.wait(500)` on async operations. Log network: `cy.intercept(..., res => console.log(res))`. Slower CI CPU = timing sensitivity.
