Software Testing & QA Services
Automated test suites, manual QA, performance testing, and security scanning — built into your delivery process so bugs get caught in staging, not production.
What software testing services does Code and Trust provide?
Code and Trust provides comprehensive software testing: unit and integration test suite development, end-to-end test automation (Playwright, Cypress), manual QA for edge cases and UX, performance load testing, and OWASP security scanning. We build testing into CI/CD pipelines so every commit is validated automatically. Our QA-embedded delivery approach has maintained a zero-critical-bug production record across 27+ client projects.
Testing types we implement
A complete QA practice isn't one tool or one methodology — it's a layered system where each type catches what the others miss. Unit tests catch logic errors immediately. Integration tests catch boundary failures. E2E tests catch user journey breaks. Manual QA catches what automation can't anticipate.
Unit testing
Jest, Vitest, pytest — core business logic coverage to 80%+
Integration testing
API contract testing, database query validation, service-to-service boundary tests
End-to-end testing
Playwright or Cypress for full user journey automation across critical flows
Manual QA
Exploratory testing, edge case hunting, cross-browser and cross-device verification
Performance testing
k6 or Locust load testing simulated to production-level traffic volumes
Security testing
OWASP ZAP scanning, dependency CVE audits, SQL injection and XSS probing
Who QA services are for
Testing is most urgently needed by teams that have already had a production incident, teams under enterprise procurement scrutiny, and teams inheriting codebases where the previous developers made no investment in automated coverage. But the best time to add tests is before the first incident, not after.
- →Teams shipping to production without any automated testing
- →Companies that have experienced critical production bugs that weren't caught in QA
- →Startups pre-Series A preparing for enterprise customer security reviews
- →Teams that inherited an untested codebase and don't know what's actually broken
Recent example
A HealthTech company had zero test coverage on a 3-year-old codebase processing patient records. We built 840 test cases over 6 weeks and added a CI pipeline requiring all tests to pass before any deploy. In the process, we discovered 12 previously unknown bugs. No production incidents in 18 months post-QA.

Zero test coverage on 3-year-old codebase processing patient records. Built 840 test cases over 6 weeks. CI pipeline added: zero tests failing before any deploy. Discovered 12 previously unknown bugs in the process. No production incidents in 18 months post-QA.
Common questions
How long does it take to add tests to an existing project?
Depends on codebase complexity. Typical timeline: 2–3 weeks to audit and write a testing plan, then 4–8 weeks to implement a comprehensive test suite from scratch. A simpler project (< 50 API endpoints) can be covered in 3 weeks.
Do you use manual or automated testing?
Both. Automated testing catches regressions on every commit. Manual QA catches the edge cases automation misses — weird user flows, browser inconsistencies, interaction states the happy-path tests don't reach.
Can you add testing without slowing down our releases?
Yes. We set up tests to run in CI (GitHub Actions) on every pull request. The first pass takes longer; once the suite is stable, CI adds 4–8 minutes to your PR process — not to deployment.
What test coverage percentage should we target?
80% line coverage for business logic. 100% for payment, authentication, and data transformation code. Coverage numbers are a guide, not a goal — what matters is that the critical paths are tested.
Do you provide ongoing QA after the engagement?
Yes. We offer quarterly QA reviews, regression suite maintenance as your product evolves, and on-call QA support for major releases.
Know your QA coverage before something breaks
Start with a coverage audit — we'll tell you exactly where you're exposed and what it would take to fix it. No obligation to proceed.
