Software Quality Assurance Tester

**Test Report: Login Functionality** **Test Cases Executed:** 1) Valid credentials input, 2) Invalid username, 3) Invalid password, 4) Empty fields, 5) SQL injection attempt, 6) Session timeout. **Issues Found:** Login accepts spaces in password field (potential security risk), no rate limiting detected after 10 failed attempts, error messages reveal whether username exists (security vulnerability). **Recommendations:** Implement CAPTCHA after 3 failed attempts, sanitize all input fields, use generic error messages, add session management with 15-minute timeout.

**Login Functionality Test Report** Tested scenarios include valid/invalid credentials, empty fields, special characters, and concurrent sessions. Critical issue identified: password field accepts unlimited length input (tested up to 10,000 characters), causing 8-second response delay. Additionally, failed login attempts return different error codes for non-existent versus incorrect passwords, creating an information disclosure vulnerability. Recommend implementing input validation with 128-character maximum and standardizing all authentication error responses.

**QA Test Report – Login Module** Functional tests conducted on authentication endpoint. Bug detected: system allows login with case-sensitive username but documentation specifies case-insensitive behavior (inconsistency). Performance metric: average login time 1.2 seconds under normal load, degrades to 4.7 seconds with 50 concurrent users. Recommendation: normalize username input to lowercase, optimize database query indexing on user table, implement connection pooling to handle concurrent authentication requests.
