CAPTCHA: reCAPTCHA v3
Grab an invisible score token with no UI and assert the server score-gate
What you will learn
- Grab a score token programmatically with grecaptcha.execute() — there is no UI to click
- Assert the server's accept/reject decision based on the returned score threshold
- Contrast invisible/score captchas with interactive checkbox/image flows
reCAPTCHA v3 — Invisible Score
No checkbox, no image grid — a 0.0–1.0 risk score is returned and the server decides who passes
v3 runs silently in the background. Calling grecaptcha.execute() yields an opaque token; the server exchanges it via siteverify for a score — 1.0 is very likely human, 0.0 is very likely a bot. There is no user interaction to drive.
Your goal:trigger the invisible check, grab the token programmatically, and assert the server's score-gate decision in #captcha-result[data-verdict].
Mode: practice — real key configured, scores come from Google.

Testing Tips
Automation hints
- ✓ There is no checkbox to click — drive the flow via the
#captcha-executebutton, not a widget iframe - ✓ With a real key, grab the token in the browser via
grecaptcha.execute(sitekey, { action: "submit" })and await the Promise - ✓ Wait for
#captcha-sdk-status[data-ready=true]before clicking — the SDK loads async - ✓ Assert the server's gate decision via
#captcha-result[data-verdict=human]and read the numeric#captcha-score[data-score] - ✓ In demo mock, lower
#captcha-mock-scorebelow 0.5 to exercise the bot branch
