QA testing services.
We provide manual and automated QA testing for web, mobile, and OTT products, embedding engineers directly into your sprint cycle to catch bugs before users do.
What we do.
QA at PettersonApps is not only a phase at the end of a project. Our testers work inside the sprint — reviewing requirements before development starts, writing test cases alongside feature work, and validating builds before they ship. Bugs are found and fixed in the same cycle, not three sprints later.
01. Manual QA
- Functional testing — feature verification against acceptance criteria
- Exploratory testing — finding edge cases and unexpected behaviors
- Cross-browser testing (Chrome, Safari, Firefox, Edge)
- Cross-device testing on real phones, tablets, and TV devices
- Usability and UX testing — flow validation, accessibility checks
- Regression testing before every release
- Bug reporting with steps to reproduce, screenshots, and severity classification
02. Automated QA
- End-to-end test automation (Playwright, Cypress, Detox, Appium)
- API testing and contract validation (Postman, REST Assured)
- CI/CD integration — automated tests run on every pull request
- Regression suites that scale with the product
- Performance testing and load testing (k6, JMeter)
- Visual regression testing — catching unintended UI changes
03. Specialized testing
- Mobile app testing across iOS and Android device matrices
- OTT and Smart TV testing across Roku, Fire TV, Android TV, Apple TV, Tizen
- IoT companion app testing — BLE pairing, real-time data sync, background connectivity
- Security testing — OWASP baseline, authentication flows, input validation
Who we work with.
Development teams without dedicated QA
Your developers are testing their own code. Bugs reach production regularly. Releases are stressful because nobody has systematically tested the full product before deployment. You need a QA engineer who owns quality — so your developers can focus on building.
Teams that need test automation
You run manual regression tests before every release and it takes days. Each release cycle gets slower as the product grows. You need an automation framework that runs in CI/CD, catches regressions in minutes, and scales with the codebase.
Companies preparing for a major launch or migration
You're about to ship a new product, roll out a redesign, or migrate to a new platform. You need a thorough QA pass — functional, cross-device, performance — before real users see it. A one-time deep audit that validates everything works.
Clients who want QA inside the sprint
You already have a development team from us and want QA included in the sprint cycle. We add a dedicated QA engineer to your team — same tools, same standups, same Jira board. Testing happens within the sprint, not after it.
How we work.
Quality at every step.
01.QA before coding
Our testers review requirements and designs before development begins — flagging ambiguity, missing edge cases, and untestable acceptance criteria. By the time the developer opens a pull request, test cases already exist. This prevents bugs instead of just finding them.
02.Real-device testing
Emulators miss real-world problems — touch behavior, network transitions, OS-specific quirks, screen-size edge cases. We maintain a device matrix covering iPhones, Android phones from major manufacturers, iPads, Roku devices, Fire TV sticks, and Smart TVs. Your product is tested the way your users will actually use it.
03.Manual & auto QA
Automation handles regression and repetitive checks. Manual testing handles exploratory work, usability, and the judgment calls that scripts can't make. We set up both and define clearly which scenarios run automatically and which need human attention — so coverage is high and effort is efficient.

FAQ.
Before you ask.
Most products benefit from both. Manual QA is essential for exploratory testing, usability validation, and edge cases that require human judgment. Automated QA is essential for regression testing, CI/CD pipeline validation, and catching regressions across a growing codebase. We typically start with manual QA and add automation once the product is stable enough for reliable test scripts.
Yes. We offer standalone QA engagements where our testers embed into your existing team — whether your developers are in-house, freelance, or from another vendor. The QA engineer uses your tools, follows your processes, and reports bugs in your tracker. No dependency on PettersonApps development.
We maintain a real device lab — not just emulators. For mobile, we test on the latest three iPhone generations, major Android devices (Samsung, Pixel, OnePlus), and iPads. For OTT, we test on physical Roku devices, Amazon Fire TV sticks, Android TV boxes, and Apple TV. We define a device matrix per project based on your user analytics and target audience.
Typically within 1–2 weeks. The first few days cover onboarding — understanding the product, setting up the environment, reviewing existing test documentation, and establishing the testing workflow. By the end of week one, the QA engineer is actively testing within your sprint cycle.
Each sprint: a test execution report with pass/fail results, bug reports with steps to reproduce and severity, and regression test results. Over time: a growing test case library, automated regression suites integrated into CI/CD, and a device coverage matrix. All documentation lives in your tools — Jira, Notion, Confluence, or whatever your team uses.
