Workflow mein code checkout, project ke Node.js version ka setup, lockfile ke mutabik dependency install aur backstop test shamil karein. BackstopJS config mein kam-se-kam ek viewport aur ek valid scenario chahiye; reports aur screenshots ko artifacts mein upload karein, taaki failed run ki jaanch ho sake.
GitHub Actions workflow banayein
Yeh workflow pull request aur main branch par push hone par BackstopJS test chalata hai. Isse project ke supported Node.js version aur apne package manager ke mutabik badlein. GitHub ke official workflow examples workflow files aur Actions setup dikhate hain; action versions ko istemal se pehle current documentation mein verify karein.

Workflow ko .github/workflows/backstop.yml naam se save karein. npm run backstop:test tabhi chalega jab yeh script package.json mein maujood ho:
{
"scripts": {
"backstop:test": "backstop test"
}
}
Agar script nahi rakhni, command ko ./node_modules/.bin/backstop test se badlein. Project mein compatible package-lock.json ho to npm ci lockfile ke anusar dependencies install karta hai. BackstopJS ko project dependency ke roop mein rakhne se CI wahi pinned version istemal kar sakta hai jo repository mein lock hui hai; global latest install se version lockfile ke bahar rahega.

BackstopJS config taiyar karein
Agar project mein config nahi hai, local development environment mein backstop init chalayein aur bani hui files review karke commit karein. BackstopJS README ke mutabik init scaffolding banata hai aur maujooda files overwrite kar sakta hai, isliye ise existing repository root par bina jaanch ke na chalayein. Default config backstop.json hai; alternate JSON ya JavaScript config ke liye --config diya ja sakta hai. BackstopJS project README config aur commands ka vivaran deti hai.
Config mein viewports aur scenarios arrays rakhein. Har scenario ko label aur url chahiye. URL aise page ka ho jo Actions runner se pahunchne layak ho.

Yeh ek chhota config udaharan hai; apne environment aur zarooraton ke hisab se URL, viewport aur paths set karein. Agar workflow ko pehle local app build aur start karni hai, to BackstopJS chalane se pehle apne framework ke build/start commands aur server-ready check jodein. Start command project-specific hota hai.
CI mein test aur reference baseline ka antar samjhein
BackstopJS ka aam workflow teen commands par aadharit hai:

Pull request workflow mein aam taur par test automatic chalayein, approve nahi. Approval baseline badalta hai; pehle visual diff review karein, phir maintainer ke roop mein zaroorat ho to locally ya alag controlled process mein approve karein.
Reports aur screenshots ko artifacts mein rakhein
Config mein report ke andar CI rakhne se JUnit-style CI report enable hoti hai; browser report ke liye browser bhi shamil kiya ja sakta hai. Report locations ko paths ke zariye apne repository layout ke mutabik set karein. BackstopJS README paths.ci_report aur ci.testReportFileName jaise overrides batati hai.

GitHub Actions artifacts workflow ke baad files ko download aur share karne dete hain. Upar ka upload step HTML report, CI report aur test screenshots ko jama karta hai. if: always() ka uddeshya test fail hone par bhi upload ki koshish karna hai; artifact action ke vartaman vyavahar aur configuration ko GitHub artifacts documentation mein dekhein.
Rendering ko consistent rakhein
BackstopJS README Puppeteer ko default engine batati hai aur Playwright support bhi document karti hai. Playwright use karne par config mein engine aur usse sambandhit scripts/options badalne hote hain. Project Docker rendering ko alag environments ke rendering antar kam karne ka ek vikalp batata hai.

- Agar local aur runner ke screenshots renderer ke farq se badal rahe hon, Docker-based rendering par vichar karein.

localhostse access karna host setup ke karan kaam na kare; BackstopJS README mein diye environment-specific host address notes dekhein.
Pull request workflow ko surakshit rakhein
Jab workflow ko PR code test karna ho aur secrets ki zaroorat na ho, pull_request ek uchit trigger hai. permissions mein sirf zaroori access dein. GitHub ke mutabik, agar kuch permissions set ki jaati hain, to baaki unspecified permissions none ho jaati hain; vivaran workflow syntax documentation mein hai.
pull_request_target ko seedhe pull_request ke badle na rakhein. GitHub chetavani deta hai ki privileged context mein untrusted PR code ko secrets ya privileged token ke saath checkout, build ya run karna jokhim bhara hai. Backstop job project code aur dependencies chalati hai, isliye fork PR test karne ke liye privileged event ka istemal na karein. GitHub ki security guidance dekhein.
Or skip the browser setup
Agar aapko CI mein browser configure kiye bina URL ka screenshot chahiye, ScreenshotNeo ek screenshot API aur MCP server hai. Ek GET request se image ya PDF capture ki ja sakti hai.

Aam samasyaon ki jaanch
| Lakshan | Mumkin wajah | Kya karein |
|---|---|---|
npm ci fail hota hai |
Lockfile nahi hai, package manifest se match nahi karta, ya CI Node version project se alag hai. | Compatible lockfile commit karein, local install ke baad use update karein, aur workflow ka Node version project ke supported version se milayein. |
| Backstop command nahi milta | BackstopJS dependency install nahi hui ya npm script maujood nahi. | Package ko project dependencies mein shamil karke lockfile update karein; script banayein ya ./node_modules/.bin/backstop test chalayein. |
| Scenario URL load nahi hota | URL runner se accessible nahi, ya local server start/ready nahi hua. | Public test URL verify karein, ya app start karne ke baad readiness check lagayein aur phir test chalayen. |
| CI mein visual diff local se alag hai | Browser engine, fonts, viewport, data/state ya rendering environment mein antar. | In settings ko milayein; zaroorat pade to BackstopJS ke documented Docker setup ka istemal karein. |
| Artifact mein report ya screenshots nahi | Test ne output nahi banaya, paths config se alag hain, ya report option enabled nahi. | report aur paths settings check karein aur upload step ke paths ko actual output directories se milayein. |
| Har run mein bade diffs aate hain | Unstable content, changing test data ya environment-specific rendering. | Deterministic test data/state istemal karein aur viewport, engine aur fonts ko fixed rakhein; diff review ke bina reference approve na karein. |
Workflow ke mukhya faisle
| Faisla | Vikalp | Asar |
|---|---|---|
| BackstopJS install | Project dependency ya global install | Project dependency lockfile se version ko reproduce karna aasaan banati hai; global install version ko project lock ke bahar rakhti hai. |
| Browser engine | Puppeteer ya Playwright | BackstopJS README Puppeteer ko default aur Playwright ko supported batati hai; engine ke mutabik config aur scripts set karein. |
| Rendering environment | GitHub-hosted runner ya Docker | Runner saral hai; Docker rendering environment ko zyada saman rakhne mein madad de sakti hai, magar networking setup samajhna zaroori hai. |
| Reports | Browser report ya CI/JUnit report, saath mein artifacts | Browser report visual review ke kaam aati hai; CI report integration mein, aur artifacts failed run ke output ko baad mein dekhne mein madad karte hain. |
| PR trigger | pull_request aur seemit permissions |
Untrusted PR code test karne ke liye least privilege rakhein; privileged pull_request_target context mein us code ko execute na karein. |
