@qawolf/testkit/web currently exposes readQRCode(page, selector).

​
Current Signature

readQRCode(page: Page, selector: string): Promise<string | undefined>
Example: 
import { readQRCode } from "@qawolf/testkit/web";

const code = await readQRCode(page, '[data-testid="login-qr"]');

​
Behavior

The helper:
  • screenshots the locator matched by selector
  • parses the result as PNG
  • decodes the QR code if one is present
  • returns undefined when no QR code is found
Example: 
import { readQRCode } from "@qawolf/testkit/web";

await page.goto("https://example.com");

const qrValue = await readQRCode(page, '[data-testid="qr-code"]');

if (qrValue) {
  console.log(qrValue);
}
