Cloud, API & Platform Engineering · Manual QA

Human testers who use your product like customers

Our manual QA testers work through your app or website by hand, following structured test cases and exploring freely, to catch the usability problems, visual glitches and odd edge cases that scripts tend to miss.

  • Exploratory testing sessions
  • Structured functional testing
  • Real-device coverage

Overview

Where human testers still win

Manual testing is skilled work, not just clicking through screens. A good tester builds a mental model of the product, then deliberately looks for places where that model and the software disagree: forms that accept nonsense, flows that lose data when you go back, messages that blame the user, layouts that collapse on smaller screens. Much of that judgment cannot be written into a script ahead of time.

The main decisions are about balance and timing. Scripted test cases give repeatable coverage and evidence for sign-off; exploratory sessions find the unexpected but are harder to measure. Testing every build is thorough but slow; testing only before release risks late surprises. Physical devices reveal real touch, performance and rendering issues that emulators miss, at higher cost. We help you weight each so testers spend their hours where humans add most.

Good manual QA produces bug reports developers can reproduce on the first try, coverage notes that show what was and was not tested, and a plain release recommendation. Over time, the reusable test cases and session notes become a record of how the product should behave, which is valuable for onboarding and future automation.

Who it’s for

Built for teams like yours

  • 01

    Startups before a launch

    Early teams about to put a product in front of customers, investors or app store reviewers who want an independent check that the main journeys hold up.

  • 02

    Teams shipping UI changes

    Product teams redesigning screens or flows often, where automated tests would break constantly and human eyes catch layout, copy and usability problems faster. Testing keeps pace with design changes.

  • 03

    Companies without in-house testers

    Businesses whose developers test their own work and need dedicated testers on demand for releases without hiring a full-time QA team. Capacity scales up or down with each release.

Why it matters

Some bugs need a human to find

Automated tests only check what someone thought to write down. A person using your product notices that a button is hidden on a small phone, that an error message makes no sense, or that a checkout breaks when you go back a step. Manual testing brings judgment, curiosity and empathy for the user into quality assurance.

It is especially useful for new features, redesigns and products changing too quickly for automated scripts to keep up. It also gives you a second pair of eyes before a launch, an investor demo or a major release that cannot afford obvious mistakes.

Every engagement includes

  • Product walkthroughwe learn your users, key journeys and known problem areas before testing begins.
  • Test plan and charterswritten scope, devices, browsers and exploratory charters agreed with you.
  • Test case libraryreusable manual test cases for critical flows, kept in your tool of choice.
  • Bug reportsclear steps, expected versus actual results, screenshots or recordings and severity.
  • Fix verificationretesting of resolved issues and nearby areas before tickets are closed.
  • Summary reportwhat was tested, open issues by severity and a recommendation for release.

Features

What our testers cover

  1. 01

    Exploratory testing sessions

    Time-boxed sessions where testers probe features freely, guided by charters focused on likely weak spots.

  2. 02

    Structured functional testing

    Written test cases that confirm each requirement and acceptance criterion behaves as specified.

  3. 03

    Real-device coverage

    Testing on physical iPhones, Android phones, tablets and desktop browsers your customers actually use.

  4. 04

    Usability and copy checks

    Confusing flows, unclear labels, broken layouts and inconsistent wording flagged alongside functional bugs.

  5. 05

    Accessibility spot checks

    Keyboard navigation, screen reader basics, contrast and focus order reviewed on key screens.

  6. 06

    Regression before release

    Focused passes over core journeys to confirm recent changes did not break what already worked.

In practice

Where manual testing fits best

  • App store submission checks

    A pass over a mobile build against common store review expectations, including permissions prompts, sign-in flows, broken links and crashes on supported devices before submission. Fewer surprises at review mean fewer delayed launches.

  • Redesign and new feature testing

    New or redesigned screens explored thoroughly on target devices, checking behavior, layout, wording and edge cases while the design is still changing too fast to automate. Findings go back to designers as well as developers.

  • Ecommerce checkout passes

    Cart, discount, shipping, payment and confirmation steps tested across devices with realistic scenarios, including going back, changing quantities and abandoned sessions. Payment testing uses sandbox or test cards only, never real customer cards.

  • User acceptance support

    Helping your business stakeholders run acceptance testing with clear scripts, a shared bug log and coaching on writing reports developers can act on. Testers help separate genuine defects from change requests.

Process

How we work

  1. 1

    Learn the product

    Testers use the product as a new customer would, read requirements and support history, and build a map of features, roles and risky areas. Questions are collected and answered before testing starts.

  2. 2

    Charter the sessions

    We write test charters for exploratory sessions and scripted cases for critical flows, and agree the device and browser matrix with you. Coverage priorities follow the riskiest areas first, and time per charter is fixed.

  3. 3

    Focused test passes

    Testers work through sessions and cases, logging notes as they go, capturing screenshots or recordings and checking each issue reproduces before reporting it. Session notes show exactly which areas were covered.

  4. 4

    Report and triage

    Bugs are filed with steps, environment, severity and evidence, then reviewed with your developers to confirm priority and clear up any questions quickly. Duplicates are merged before developers see them.

  5. 5

    Retest and summarize

    Fixed issues are retested along with nearby features, and a short summary covers what was tested, what remains open and our release view. Open risks and untested areas are stated plainly.

FAQ

Frequently asked questions

Anything else about Manual QA? Ask us directly.

  1. Yes. Automation is excellent at confirming known behavior quickly and repeatedly, but it does not notice a confusing screen, a layout that breaks on one device or a flow that technically works yet frustrates users. Manual testing finds the problems nobody anticipated, which are often the ones customers complain about.
