SonarQube report

Security Rating (D)

• What it measures: Vulnerabilities and security weaknesses in your code
• Rating scale: A (best) → E (worst)
• D Rating means: At least one High severity security issue exists
• Common issues:
  • SQL injection vulnerabilities
  • Hard-coded credentials/passwords
  • Weak encryption/cryptography
  • Cross-site scripting (XSS)
  • Insecure deserialization
• Impact: Security issues can be exploited by attackers

Reliability Rating (D)

• What it measures: Bugs and issues that could cause system failures
• Rating scale: A (best) → E (worst)
• D Rating means: At least one High severity reliability issue exists
• Common issues:
  • Null pointer dereferences
  • Resource leaks (memory, file handles)
  • Infinite loops
  • Incorrect exception handling
  • Race conditions
• Impact: Reliability issues can cause crashes or unexpected behavior

Maintainability Rating (A)

• What it measures: Technical debt and code quality issues
• Rating scale: A (best) → E (worst)
• A Rating means: Excellent! Relatively low technical debt compared to codebase size
• What it considers:
  • Code smells/complexity
  • Duplicated code
  • Comment density
  • Test coverage
  • Rule violations
• Positive indicator: Your code is relatively clean and easy to maintain

Open Issues

• Security: 1 open issue (likely a High severity vulnerability)
• Reliability: 64 open issues (some are High severity)
• Maintainability: 283 open issues (mostly minor code smells)

Coverage (0.0%)

• What it is: Percentage of code covered by unit tests
• Current state: 0.0% - No unit tests are covering your code
• Lines to cover: 18,000 lines of code that need test coverage
• Why it matters:
  • Tests ensure code works correctly
  • Tests prevent regression bugs
  • Tests document expected behavior
  • Essential for refactoring and maintenance

Duplications

• What it measures: Repeated code blocks
• Impact:
  • Maintenance overhead (fix bugs in multiple places)
  • Code bloat
  • Inconsistent changes
• Best practice: Keep duplication under 3-5%

Accepted Issues (0)

• What it is: Issues that were reviewed and accepted as “won’t fix”
• Current state: 0 means you haven’t marked any issues as acceptable
• Good practice: Use this for issues that are false positives or intentionally designed

Valid Issues (0)

• What it is: Issues that were confirmed as real problems but not fixed
• Current state: 0 means either all issues are being addressed or not reviewed yet

Priority Recommendations

Immediate Action Required 🔴

1. Fix the High severity Security issue - This is critical
2. Fix the High severity Reliability issues - Prevent system crashes
3. Add unit tests - Start with critical business logic

Medium Term 🟡

1. Address remaining Reliability issues (64 total)
2. Reduce code duplications if significant
3. Monitor Maintainability - Keep it at A

Long Term 🟢

1. Establish test coverage target (aim for 70-80%)
2. Implement CI/CD with quality gates
3. Regular SonarQube reviews

How to Improve

# 1. Analyze specific issue types
# Security issues
sonar-scanner -Dsonar.issues.include=SECURITY
 
# Reliability issues
sonar-scanner -Dsonar.issues.include=RELIABILITY
 
# 2. Focus on specific severities
# Show only Blocker, Critical, Major issues
sonar-scanner -Dsonar.issues.severities=BLOCKER,CRITICAL,MAJOR
