QA testing and test automation services
Manual, exploratory, automated, performance, API and accessibility testing for web and mobile apps. Find the bugs before your customers do.
Overview
TopNotch is a software testing company that helps product teams release faster without sacrificing quality. Our QA testing services cover everything from a one-off pre-launch test to fully managed, outsourced QA for every release.
We build reliable test automation in your CI pipeline, run focused exploratory testing on new features, and report bugs your developers can reproduce and fix on the first try.
Automation gives us speed and coverage, but people decide what quality means. Every engagement keeps a human in the loop: experienced testers design the scenarios, review automated results, investigate failures and explore the edge cases scripts miss. That matters even more when you're testing AI-developed products or code written with AI assistants, where output can look right and still be wrong.
What's included
Manual and exploratory testing
Structured test cases plus experienced testers exploring your product like real users, across browsers, devices and operating systems.
Test automation
Maintainable end-to-end, API and regression suites with Playwright, Cypress, Selenium or Appium, running in your CI pipeline. Our engineers review every failure, so your team gets real bugs, not noise.
Performance and load testing
Realistic traffic simulation with k6 or JMeter before launches and peak seasons, with clear bottleneck analysis.
API testing
Contract, functional and negative testing for REST and GraphQL APIs, including authentication and error handling.
Accessibility testing
WCAG 2.2 audits combining automated scans with manual screen-reader and keyboard testing.
QA consulting and outsourced QA
Test strategy, release process design, and dedicated outsourced QA teams that scale with your roadmap.

Common questions
Manual and exploratory testing, test automation, performance and load testing, API testing, accessibility testing, and QA consulting or fully outsourced QA.
Playwright, Cypress, Selenium and Appium for UI automation, Postman and code-based frameworks for APIs, and k6 or JMeter for performance testing. We also work within your existing tools.
Yes. We provide dedicated outsourced QA teams on a monthly retainer, working inside your Jira or Linear, GitHub and Slack.
Yes. We offer a free 30-minute assessment to review your release process, current test coverage and biggest risks.
No. We use automation and AI tools to move faster, but a human always stays in the loop. Our testers review automated results, investigate every failure and run exploratory testing on new features, because tools alone miss the problems real users find. This is especially important for AI-developed products.
