MANUAL QA TESTING SERVICES

You've probably used software where critical bugs were caught by manual testers like ours.

We've delivered manual qa testing services across industries. Whether you're building web apps or mobile platforms, we can help.

Our Mobile Developers
Shield

Functional Manual Testing

We verify every feature and function works correctly according to specifications and user requirements. Our functional manual testing service includes positive and negative testing, boundary value testing, equivalence partitioning, and requirement validation.

Automated tests only check what they're programmed to check missing unexpected behaviors and requirement misunderstandings. Human testers validate software actually solves user problems correctly. Our process includes test case design, systematic execution, defect documentation, retest verification, and traceability reporting ensuring every requirement is met precisely.

Shield

Exploratory Testing

We independently examine your application using exploratory testing and real-world experience to find potential issues. Some of the services we offer include session-based testing, charter-based exploration, bug detection, and creative scenario testing.

Test scripts cannot incorporate every possibility users will create while using your application. Our testers work as creative users by attempting to discover bugs that the original developers overlooked during their testing process. They use their intuition, experience, and knowledge of the industry to identify usability issues, if there are problems with the clarity of your messages, confusion with workflow, or unexpected errors that they do not identify when executing scripted tests.

Shield

Usability Testing

We use a user experience perspective to review software for friction, confusion, and design issues that can affect user satisfaction. Usability testing comes in many forms, including: task completion testing; cognitive walkthrough testing; heuristics evaluation testing, and accessible testing.

Software can be fully functional but if the user experience is poor, users tend to get frustrated and potentially bail out and leave a negative review. Therefore, we will look at where users tend to get stuck most, and our review will examine your navigation, visual hierarchy, error messages, feedback while loading, and how to find user guides in order to ensure your software is functional and enjoyable!

Shield

Regression Manual Testing

We verify existing features still operate correctly after development code updates or new features. Our regression manual testing service includes smoke testing, sanity testing, critical path verification, and comprehensive regression cycles.

While automated regression testing can execute fast, it does not provide the human judgement required to identify visual regressions, UX degradation and subtle behavioural changes, we offer highly thorough human based regression testing by identifying issues found by automation, and executing an automated regression with a human verification, and include priority based testing, impact assessment, and validation of integration/cross-feature testing as part of our regression testing process so that no updates to software breaks existing functionality that users rely upon.

Shield

User Acceptance Testing (UAT)

UAT is performed in an organized manner to confirm that the software meets the intended requirements of the user. Our UAT services will include developing scenarios, coordinating efforts with actual business users, collecting feedback, and providing formal documentation confirming acceptance of the Software.

Tech-developed software often does not conform with the methodology that the user intends for the software to be built resulting in difficulty accepting the work at the time of delivery. We also facilitate UAT and verify that the business user can confirm that the functionality of the Software was designed to meet their needs. This is accomplished through validating the acceptance criteria, testing the Software against actual scenarios, conducting interviews with various stakeholders to gather feedback and fully documenting for formal acceptance to build assurance before launching the Software.

Shield

Cross-Browser & Device Testing

We will conduct manual desktop/browser testing across a variety of platforms/devices to determine rendering inconsistencies and cross-browser compatibility problems within your application. This includes Windows, Mac OS, iOS and Android with Chrome, Firefox and Edge.

Automated tools (like Selenium) will provide you with technical compatibility, however, they do not check for visual differences between browser versions, layout differences or even platform-specific UX issues that the user would experience. Manual testing will verify how each user's environment is displayed and operated. In addition, we will conduct a complete manual test of your application's response to touch events, browser-specific properties, and platform-specific behaviors to verify the user's experience is consistent across all browsers and devices.

Shield

Mobile App Manual Testing

Mobile applications are tested on physical devices evaluating functionality, performance and User Experience (UX) by performing tests including gesture validations, Orientation Testing, interrupted tests (i.e., phone call) and offline behavior testing, as well as verifying compliance with App Store Guidelines.

The challenges of testing Mobile Apps are unique due to the large variety of screen sizes, operating systems, device capabilities and user contexts that cannot be validated using just Automation. Physical Device Testing tries to replicate ‘real’ world experiences by testing the following functionality on a real device: installing / uninstalling, granting permissions, receiving Push Notifications, Background Processing and Battery Consumption which will meet user expectations.

Shield

Ad-Hoc & Monkey Testing

Our testers will complete unstructured and random tests that will result in the detection of crashes, errors, and random behaviours. The ad-hoc tests we conduct will be the following: Random clicking, input testing of invalid values, stress testing, and pushing the limits of your application that are beyond the normal case.

There are many things that users do that cannot be accounted for by automation such as clicking very quickly, hitting the browser back button multiple times, disconnecting from the network, and inputting random value combinations. An experienced tester will take on the role of a mischievous tester that is actively trying to break your system. Our chaos testing process reveals edge cases, error handling gaps, validation issues, and crash scenarios ensuring that your application tolerates abuse and does not break.

AI-Powered Features in Manual Testing Services

While our manual testing service focuses on human expertise, we integrate AI tools enhancing tester productivity, test coverage, and defect detection without replacing human judgment.

Down ArrowAI-Assisted Test Planning

Test creators and scenarios use AI tools to speed up the process while providing Testers with human creativity and knowledge of the domain about the acceptable and acceptable test plans.

Down ArrowIntelligent Bug Clustering

Auto-classify all like defects automatically using ML to group like defects. Using AI will help us identify defect trends across the application so we can help developers find the root cause instead of just addressing individual symptoms.

Down ArrowSmart Test Prioritization

AI predicts risk based on code changes/areas/places where bugs are likely. Manual testing resources can be focused on the areas of highest likelihood of defect occurrence.

Down ArrowAutomated Reporting Dashboards

Using AI dashboards to track overall testing progress, total defect trends, total quality metrics, and other reports automatically for stakeholders without any manual reporting.
