FAQ

What is "ReCAPTCHA couldn't find user-provided function: vueRecaptchaApiLoaded"?

It's because google's recaptcha have been loaded before your app. You can simply ignore it because vue-recaptcha can still detect and render recaptcha. If you care about this, try to move the script tag of recatpcha after to your app.

How to test vue-recaptcha?

You can mock window.grecaptcha to bypass google's recaptcha. Here is an example which work with jest.

How about an e2e testing (or integration testing)?

Please reference to recaptcha's FAQ.

<script src="https://www.google.com/recaptcha/api.js?onload=vueRecaptchaApiLoaded&render=explicit" async defer>
</script>
