{
  "SUMMARY": "Missing password validation message",
  "BUG_DESCRIPTION": "The password validation error message is not displaying when an invalid password is submitted during registration. The test enters a password 'abcdefg' which lacks required special characters, capital letters, and numbers. Upon clicking Register, the system should display the validation message '*Please enter 1 Special Character, 1 Capital 1, Numeric 1 Small' but instead returns an empty string. This is a consistent failure occurring in all 10 test runs with a 100% failure rate, indicating a persistent defect in the validation message display mechanism.",
  "IMPACT": "Users attempting to register with non-compliant passwords will receive no feedback about password requirements, leading to registration failures, user frustration, and potential account abandonment. This could result in reduced user acquisition rates and negative user experience, as users won't understand why their registration is failing or what password format is required.",
  "CONFIDENCE": 95,
  "ROOT_CAUSE": "The validation message element exists in the DOM but is not being populated with the error text when validation fails. Given the 100% failure rate across 10 consecutive runs, this appears to be a broken connection between the validation logic and the UI display mechanism. The validation itself may be working (preventing registration) but the error message handler is failing to set the text content of the message element.",
