Quality Built Into Every Sprint — Not Bolted On Before Launch

QA as a final phase is a myth that costs you in production bugs, emergency patches, and user trust. We integrate automated testing and structured manual QA into every sprint so quality is a continuous property of the codebase — not a last-minute gate.

CONTINUOUS QAAutomated and manual testing runs on every sprint — not once before release

Why QA as a Phase Fails

Pain PointQA as a Final PhaseHardened Soft
Bugs found late cost 10x moreQA sprint at the end discovers architectural issues too late to fix cleanlyTesting integrated from sprint one — issues caught when the cost to fix is hours, not weeks
No regression safety netManual testing repeated every release, humans miss things under pressureAutomated regression suite runs on every commit — breakage is caught before it reaches staging

CORE CAPABILITIES

What We Build and Operate Under QA Engagements

Automated Test Suite Architecture

  • Unit testing: Jest, Vitest, PyTest — isolated, fast, and deterministic
  • Integration testing: API contract tests, database interaction tests, service boundary tests
  • E2E testing: Playwright or Cypress for critical user flows across real browsers
  • Test data management: factories, fixtures, and seed scripts for reproducible test state
  • Test parallelization and sharding for fast CI pipeline execution

CI/CD-Integrated Quality Gates

  • Automated test runs triggered on every PR — merge blocked on failure
  • Coverage thresholds enforced as a pipeline gate — coverage can't decrease without approval
  • Flaky test detection and quarantine system — flaky tests flagged, not ignored
  • Test result dashboards with trend tracking per branch and per engineer
  • Parallel test execution across multiple runners to keep pipelines under 10 minutes

Performance & Load Testing

  • Baseline performance benchmarks established in sprint two — tracked every release
  • k6 or Locust load testing scripts for API endpoints and critical flows
  • Database query performance testing: slow query detection and N+1 identification
  • Frontend performance: Lighthouse CI, Core Web Vitals tracking, and bundle size monitoring
  • Stress testing for launch events and traffic spikes

Manual QA & Exploratory Testing

  • Structured test case authoring aligned to acceptance criteria per user story
  • Exploratory testing sessions focused on edge cases automated tests miss
  • Cross-browser and cross-device testing matrix for web applications
  • Regression testing checklists per release with pass/fail tracking
  • Bug triage, severity classification, and reproduction steps documented in Jira

Security & Dependency Testing

  • SAST (Static Application Security Testing) integrated in CI: Snyk, Semgrep, or CodeQL
  • Dependency vulnerability scanning on every build — CVE alerts and remediation guidance
  • OWASP Top 10 test scenarios for web applications
  • Secret scanning to catch API keys and credentials committed to the repository
  • Basic penetration test scenarios for authentication, authorization, and injection attacks

QA Process & Reporting

  • Test strategy document per project: scope, coverage targets, and tooling decisions
  • Sprint-level QA sign-off checklist before any deployment to production
  • Defect density tracking: bugs per feature area, trend analysis per sprint
  • Test coverage reports integrated into PR review workflow
  • Monthly quality metrics report: coverage trends, bug rates, pipeline health

HOW WE WORK

QA Integrated Into the Development Lifecycle

SPRINT 1

Test Strategy & Tooling Setup

We define the test strategy, select tooling, and establish the CI/CD quality gates. Coverage targets are agreed. The test infrastructure is set up alongside the application infrastructure — not after.

EACH SPRINT

Continuous Test Authoring & Execution

New features ship with unit and integration tests. E2E tests are added for every new critical user flow. Automated regression runs on every PR. Manual exploratory sessions happen mid-sprint, not at the end.

PRE-RELEASE

Release Qualification

Sprint-level QA sign-off checklist completed before any production deployment. Performance benchmarks verified. Security scans pass. No green deploy without a green QA gate.

HANDOVER

Test Suite Transfer & Documentation

Full test suite transferred to your repository. Test strategy document, coverage reports, and pipeline configuration handed over. Your team inherits a tested, documented codebase — not a black box.

WHY HARDENED SOFT

What Every QA Engagement Includes

Quality at Hardened Soft is a continuous property of the codebase — not a phase. Every sprint ships with tests. Every pipeline enforces coverage gates. And 100% of the test suite is yours — owned, transferred, and documented so your team can maintain and extend it independently.
FAQ

Common Questions About QA Engineering

Can you add QA to a project that's already in development?

Yes. We start with a test audit — coverage assessment, existing test quality review, and CI pipeline review. We then prioritize coverage for the highest-risk, least-tested parts of the codebase and work outward from there.

How do you decide between Playwright and Cypress for E2E?

Playwright for most new projects — better multi-browser support, faster execution, and a more maintainable API. Cypress if the team already has significant investment in it or prefers its debugging experience. We document the reasoning in the test strategy.

What coverage percentage do you target?

Coverage percentage is a proxy metric, not a goal. We target meaningful coverage of business-critical paths and high-risk areas. Typically 70–80% line coverage for backend services, with 100% coverage on payment flows, auth logic, and data mutation endpoints.

Do you do penetration testing?

We integrate OWASP Top 10 test scenarios and automated security scanning (Snyk, Semgrep, OWASP ZAP) into the CI pipeline. Full third-party penetration testing requires a specialist — we can recommend vetted firms and prepare your application for their engagement.

How does QA integrate with your 2-week sprint model?

QA is not a separate phase at the end of a sprint. Test authoring happens alongside feature development. Exploratory testing sessions happen mid-sprint. The sprint demo is only shown on a build that has passed all automated gates and the QA sign-off checklist.
