What known qualities and quality gates can you list in the software quality assurance process?

In the process of software quality assurance (QA), various quality gates and control points are used to ensure stability and compliance with requirements. These include:

• Code Quality: style, readability, duplication, complexity, test coverage checks.
• Static Code Analysis: automatic code review for errors, vulnerabilities, and standard violations.
• Unit Tests: testing individual components.
• Integration Tests: testing interaction between modules.
• Functional Tests: verifying functionality according to requirements.
• Performance Tests: assessing speed and load capacity.
• Security Tests: checking application security.
• Code Coverage: percentage of code covered by tests, with minimum thresholds.
• Build Success: successful build without errors.
• CI Checks: automatic checks on each commit.
• Code Review: manual or automated review by colleagues.
• Bug Rate / Defect Density: metrics of bugs per code unit.
• Release Readiness: readiness check including documentation and testing.

These checkpoints are often integrated into CI/CD pipelines to automatically block code progression if certain quality criteria are not met.
