Lazy-loaded iframe blank dikh raha ho to pehle us iframe ko viewport mein scroll karein, phir iframe ke andar kisi meaningful element ke visible hone ka wait karein. Us assertion ke baad screenshot lein. Sirf iframe ka box visible hona, page load event, ya networkidle embedded UI ke ready hone ki guarantee nahi deta.
Iframe content ko ready karke screenshot lein
Iframe element aur uske andar chalne wali application alag readiness stages hain. Iframe ko locate karna ya uska load event milna yeh nahi batata ki expected heading, chart, report ya doosra UI render ho chuka hai. Playwright ke FrameLocator se iframe ke andar locators banayein, aur locator assertions se intended content ka wait karein.
const frame = page.frameLocator('iframe#report');
await page.locator('iframe#report').scrollIntoViewIfNeeded();
await expect(frame.getByRole('heading', { name: 'Report' })).toBeVisible();
await page.screenshot({ path: 'report.png' });
Is example mein iframe#report aur Report ko apne page ke stable selector aur expected content se badlein. Agar iframe mein heading nahi hai, to kisi aur meaningful, stable element—jaise status label ya test-specific marker—par assertion karein.

Yeh sequence kyun kaam karta hai
- Sahi iframe chunein. Stable selector use karein. Frame locator strict hota hai: agar selector ek se zyada frames match kare, operation error dega. Multiple embeds hon to selector ko narrow karein. FrameLocator documentation dekhein.
- Lazy loading trigger karein. Agar iframe viewport se bahar hai, us element par
scrollIntoViewIfNeeded()chalayein. Lazy load kab trigger hoga, yeh site ki implementation par nirbhar karta hai; scroll karna practical step hai, Playwright ki universal guarantee nahi. - Iframe ke andar content assert karein.
frameLocatorke through inner element locate karke web-first assertion lagayein. Locator assertions condition pass hone tak retry karti hain. Frames guide iframe access patterns samjhati hai. - Assertion pass hone par capture karein. Isse screenshot intended UI ke render hone ke baad hota hai, na ki sirf document lifecycle event ke baad.
Kaun sa wait sahi hai?
| Wait ya check | Kya establish karta hai | Is case mein istemal |
|---|---|---|
| Iframe element visible | Outer iframe box visible hai; yeh inner application ke render hone ko establish nahi karta. | Sirf tab kaafi nahi; iske baad inner content assert karein. |
frame.waitForLoadState() |
Frame document lifecycle state tak pahunch gaya. Playwright ke mutabik aam taur par iski zarurat nahi hoti, kyunki actions auto-wait karte hain. | UI readiness ka substitute na banayein. Frame API dekhein. |
networkidle |
Network activity ke lifecycle signal ka wait karta hai. | Playwright ise tests ke liye discourage karta hai; intended content par web assertion use karein. Frame API dekhein. |
| Iframe ke andar locator assertion | Expected element ki condition, jaise visible hona, pass hui. | Screenshot se pehle content readiness check ke liye use karein. |
| Fixed delay | Bas nirdharit waqt beet gaya; content ready hone ka pramaan nahi. | Is par nirbhar na karein. Playwright time-based waits ko flaky batata hai aur debugging ke liye rakhta hai. Frame API dekhein. |
Page screenshot ya iframe element screenshot?
page.screenshot() page ka screenshot leta hai. Agar poora scrollable page chahiye, to fullPage option use karein; default capture viewport tak hota hai. Specific iframe element ka screenshot lena ho to locator-based screenshot par vichar karein. Element screenshot API element ko view mein scroll karti hai aur actionability checks karti hai; Playwright locator-based screenshot recommend karta hai. ElementHandle screenshot documentation dekhein. Dono tarike content-readiness assertion ki jagah nahi lete.

Assertion ke baad bhi iframe blank ho to
- Selector match verify karein: iframe selector intended embed ko target karta hai aur multiple frames ko match nahi karta, yeh jaanchein.
- Inner locator verify karein: expected heading ya marker ka naam aur role actual iframe UI se milayein. Galat expectation timeout kara sakti hai.
- Frame URL dekhein: confirm karein ki iframe expected document load kar raha hai.
- Errors inspect karein: browser console errors aur failed network requests dekhein. Yeh batate hain ki problem loading ya application mein ho sakti hai; logs ke bina kisi specific third-party failure ko maan lena sahi nahi.
- Installed Playwright version check karein: yahan linked docs current hain, version-pinned nahi. Agar method ya option available na ho, apne project ki installed version aur us version ki API docs verify karein. Frame locator Playwright 1.17 mein introduce hua tha; release notes dekhein.
