CAPTCHA-Verwaltung für Prüfungen zur Einschreibung von Universitätskursen

Registrierungssysteme für Universitätskurse verwenden reCAPTCHA v2, um Anmeldeformulare, Kurssuchseiten und Stundenplaner zu schützen. QA-Teams, die diese Systeme testen, müssen CAPTCHAs in mehreren Testszenarien verarbeiten – Registrierungsworkflows, Wartelistenlogik, Sitzplatzverfügbarkeit und Fristendurchsetzung. Hier erfahren Sie, wie Sie die Lösung von CAPTCHAs in Registrierungstests integrieren.
