# QA: Automated and manual testing, load, and security.

**Software that’s ready for release**

Quality assurance that finds risk early, protects critical workflows and gives teams evidence to release with confidence.

## Quality throughout delivery

Quality assurance gives teams evidence to make informed decisions throughout delivery. We identify the critical workflows and standards that guide testing across functionality, integrations, performance, accessibility and security.
Automated and manual testing are combined across development and release, with greater depth where reliability matters most. The result is a clear record of what has been checked and the information teams need to prepare for release.

What this includes:
- **Test strategy & management**: Planning risk-based coverage, acceptance criteria, environments and test data, with coordinated execution, defect reporting and evidence for release or regulatory review.
- **Functional & integration testing**: Checking features, business rules, data flows, workflows and system connections through exploratory and acceptance testing.
- **Test automation**: Designing and maintaining automated tests across the delivery pipeline for repeatable regression coverage.
- **Performance & reliability testing**: Assessing response times, capacity, stability and recovery under expected demand, sustained operation and failure conditions.
- **Security testing**: Assessing vulnerabilities, access controls, data protection and security-sensitive workflows, then verifying that identified issues have been addressed.
- **Accessibility & compatibility testing**: Testing accessibility against recognised standards and compatibility across devices, browsers, operating systems, assistive technologies and regional settings.

How we work:
- **Testing directed by risk**: Critical workflows, recent changes and the likelihood and impact of failure determine testing priorities. Coverage is agreed with everyone involved and revised as requirements, risks and findings develop.
- **Methods matched to the question**: Exploratory testing and automated checks are selected according to what needs to be understood or verified. Representative environments and test data make findings relevant and important checks repeatable.
- **Findings that support decisions**: Reports explain what was tested, what was found and where uncertainty remains. Issues include evidence and likely impact, helping teams prioritise fixes and decide on release readiness or further testing.

Stack: End-to-end & devices: Playwright, Cypress, Selenium, Appium, Detox, Maestro, BrowserStack · Unit, API & contract: Jest, Vitest, Pytest, JUnit, Postman, Pact · Load & security: k6, JMeter, Burp Suite, OWASP ZAP, Semgrep · Evidence & accessibility: GitHub Actions, TestRail, axe, NVDA.

Questions we get about this discipline:
- **Can you provide QA without taking over development?** Yes. QA can be an independent service or part of a wider delivery team. We agree the product areas, risks, access and reporting needed to test effectively, then work with the people responsible for addressing findings.
- **Where do you start with a product that has few tests?** We identify its critical workflows and the failures that would have the greatest impact. Initial testing establishes what is working, where risk is concentrated and which repeatable checks would provide the most value.
- **Do you perform manual testing as well as automation?** Yes. Exploratory testing helps investigate behaviour and uncover issues that scripted checks may miss. Automation supports repeatable checks where it is useful and maintainable; the mix depends on the product and the questions testing needs to answer.
- **Can you test performance, security, accessibility and compatibility?** Yes. We define the required coverage for each area based on the product, its users and its risks. Specialist testing can be included as focused work or coordinated with broader functional testing.
- **Will you tell us whether the product is ready to release?** We report what was tested, what was found and what remains uncertain, including the likely impact of unresolved issues. That gives the people responsible for release a clear basis for their decision.
