# Quality Assurance & Testing

> Automated and exploratory testing embedded in delivery so quality scales with release speed.

We treat quality as a product capability, not a final gate. Our teams build test strategy, CI-integrated automation (unit, API, E2E), performance and security testing, and the reporting that helps engineers fix issues fast. With Playwright, Cypress, Jest, and complementary manual exploration, we reduce regression risk while keeping release cadence high.


## Key Capabilities

- **Test Automation**: CI-native unit, API, and end-to-end suites that catch regressions before users do.
- **Performance & Load**: Load, stress, and soak testing against realistic traffic so scale is a known quantity.
- **Security Testing**: SAST/DAST, dependency scanning, and targeted checks aligned with your threat model.
- **Exploratory QA**: Human-led testing for edge cases, UX friction, and scenarios automation cannot cover alone.

## Technologies We Use

Playwright, Cypress, Jest, Vitest, Selenium, k6, Postman, OWASP ZAP, BrowserStack

## Our Approach

1. **Planning**: Risk-based test strategy
2. **Test Design**: Cases, data, and coverage map
3. **Automation**: CI pipelines and stable suites
4. **Execution**: Regression, exploratory, and release
5. **Reporting**: Defect signals teams can act on
6. **Improve**: Flake reduction and coverage growth

## Budgets of All Sizes

We work with budgets across the full range. The team adapts scope, size, and engagement model to what you can spend, without lowering the bar on how we build.

- **Enterprise**: Full delivery teams for complex platforms, with the security, compliance, and process rigor large organizations expect.
- **Growing Teams**: Flexible engagements that scale with you. Add capacity when you need it, scale back when you don't, without renegotiating from scratch.
- **Small Business & Startups**: Lean, focused builds that get the essentials right. We help you trim scope, not quality, so a modest budget still ships a solid product.

## Why This Matters

- **Higher Quality**: Fewer production defects and clearer confidence at every release.
- **Safer Speed**: Automation that unlocks frequent releases without gambling on quality.
- **Lower Rework Cost**: Bugs caught early cost a fraction of production incidents.
- **User Trust**: Stable products that do what they promise, every time.

## Frequently Asked Questions

### What testing services does OOZOU offer?

Automated and exploratory testing embedded in the delivery process: unit and integration tests, end-to-end suites, performance testing, and security scanning, so quality scales with release speed instead of slowing it down.

### Which testing tools does OOZOU use?

Playwright, Cypress, Jest, and Vitest for functional and end-to-end testing, k6 for performance, OWASP ZAP for security scanning, and BrowserStack for cross-device coverage.

### Can OOZOU add automated tests to an existing codebase?

Yes. We start with the highest-risk user journeys, build an end-to-end safety net first, and then push coverage down into integration and unit tests as the suite earns trust.

### Does OOZOU do manual testing too?

Yes. Exploratory testing by people who understand the product finds what scripts miss. We combine it with automation rather than choosing one or the other.
