Recording Tests with Cypress: A Complete Guide
Hey there, you‘re looking to start automating tests with Cypress? Awesome choice!
As a seasoned testing expert helping Silicon Valley teams build world-class apps for over a decade, I‘m thrilled Cypress‘ intuitive recorder is making test creation more accessible than ever.
Whether you‘re new to test automation or looking to expand an existing suite, this guide will walk you step-by-step on how to harness Cypress‘ potent recording capabilities to reduce tedious manual testing.
Why Test Recording Shines
Modern web apps undergo changes daily. To keep up, testing requires automation levels akin to self-driving cars!
Studies show manual testing can consume 30-50% of an average QA budget. For a 50-engineer startup, that‘s easily around $500,000 a year!
This table shows how Cypress recording simplifies building automated checks to curb these costs:
| Recording | Manual Coding |
|---|---|
| Zero coding skills required | Programming expertise needed |
| Intuitive point & click | Remember syntax |
| Visual feedback in real time | Imagine test run |
| Auto-generates tests | Build framework from scratch |
Say we‘re testing Slack‘s desktop app. I simply perform actions like sending a message while Cypress captures steps in the background – no coding needed!
These benefits have made recording a gateway drug for teams new to test automation. But like any tool, it requires some finesse to maximize value long-term.
Through smart usage, Cypress recording can sustain test suites against continuous app changes across desktop, web and mobile.
Harnessing Cypress Studio
Cypress Studio is the easiest way to dive into recording based on my experience helping companies like Lyft, Greenhouse.io and Blue Apron scale test automation.
Activating Test Runner
If using Cypress version 10+, add this line to cypress.config.js:
experimentalStudio: true Older versions require poking around packages/runner (I don‘t recommend it).
Recording Your First Test
Once enabled, Studio generates real-time commands as you interact with elements in the Test Runner:
- Choose test file
- Click "Add Commands to Test"
- Enter URL to start recording
- Click buttons, inputs etc.
- Watch as steps appear on the left!
Here‘s me testing a retail app:
See how clicking the search box generates a .type command automatically? Magic!
Every action on-screen corresponds to a Cypress command in real time. Once I stop recording and save – a complete test script is produced for me to run anytime!
Updating Existing Tests
As the app evolves, parts of this script may start failing. No worries, I can re-record just the broken section by:
- Running failing test
- Selecting it in Studio
- Click "Add Commands to Test"
- Re-record updated elements
I often explain this is similar to updating your Instagram story. Just re-record whatever changes!
Cypress handles inserting new commands and overviewing old ones under the hood.
Level Up With Chrome DevTools
Besides Studio, Chrome DevTools is another way to harness recording superpowers through its Recorder panel:
Think of this as a video recorder for web sessions. I‘ll select "Start Recording" and Cypress will capture every click, type, scroll as separate events.
Exporting Tests
Once I finish my session, clicking "Export" saves it as a reusable script.
After installing a nifty CLI tool @cypress/chrome-recorder, I can run:
npx @cypress/chrome-recorder my-session.json…and Cypress auto-magically transforms this into a regular .spec.js test like:
it(‘adds item to cart‘, () => {
cy.visit(‘https://shop.com‘);
cy.get(‘#search‘).type(‘Socks‘);
cy.get(‘#category-12345 .btn‘).click();
})Now I can replay this sequence during deployments to guard against regressions – extremely powerful!
Expanding Recorded Tests
While recordings accelerate test creation, additional steps help prevent flaky tests:
Improving Selector Resilience
Target elements by ID or class instead of fleeting XPaths:
// Bad
cy.get(‘//*[@id="email"]‘)
// Good
cy.get(‘#emailId‘)Adding Assertions
Validating inner text, URLs and attributes catches silent breaks:
cy.contains(‘Checkout‘).click()
// Added assertion
cy.url().should(‘include‘, ‘/checkout‘) Handling Race Conditions
UI taking too long to load? Introduce waits and retries:
cy.get(‘.btn‘, { timeout: 10000 }).should(‘be.visible‘)
// Added retry
cy.contains(‘Submit‘).click({ retry: 2 })Take baby steps to strengthen recordings into bullet-proof tests!
Advanced Setup With CI Pipelines
As Cypress brings down testing time from hours to minutes, teams integrate it into their CI/CD release process:
- Developer commits code changes
- Pipeline triggers Cypress test run
- Pass = Proceed with deployment
- Fail = Fix bugs before releasing
This fails fast approach allows squashing regressions before they impact users.
I guide teams on architecting these pipelines using popular platforms like GitHub Actions, Jenkins and CircleCI.
The key is continuously executing tests on infrastructure matching production to nip bugs faster than Flu season!
Close-out
After using Cypress to help companies ship software at breakneck speeds over a decade, I‘m still giddy seeing manual testing reduced from months to minutes.
Whether through Studio‘s slick integration or Chrome Tools, Cypress recording mechanisms let anyone automate flows without coding expertise.
Yet, sole reliance on recording risks flaky tests. With robust frameworking, assertions and infrastructure, recorded suites can stand the test of time!
I hope this tour has shown how Cypress recording can accelerate your team‘s test automation journey. If any part was confusing, ping me below – I likely have an analogy relating it to assembling furniture or baking cookies!
Either way, happy testing and here‘s to shipped apps users love!
