When manual testing
is the right choice
You need to validate new features quickly before investing in automated scripts.
You are testing a highly dynamic UI where automated locators break too often.
You want real feedback on usability, accessibility, and visual accuracy.
You are working with incomplete or frequently changing requirements.
You need exploratory testing to uncover hidden issues beyond the “happy path.”
You are localizing your app and need human eyes to catch cultural or language errors.
You are releasing a hotfix or patch where automation coverage is missing.
You want to avoid automation overhead for short-lived or low-risk features.
Manual software testing services we provide
DeviQA provides functional, UI/UX, regression, cross-browser, cross-device, exploratory, and localization testing for web, mobile, and desktop applications.
Functional testing
We test features, business rules, input validation, error handling, and user flows against functional requirements.
UI/UX testing
We test interfaces against design requirements and identify layout, navigation, accessibility, and usability defects.
Regression testing
We retest affected and business-critical functionality after code, configuration, integration, and dependency changes.
Cross-browser & cross-device testing
We test functionality and interface behavior across the required browsers, operating systems, devices, and screen resolutions.
Exploratory testing
We use structured exploratory sessions to identify edge cases, unexpected system behavior, and defects not covered by predefined test cases.
Localization testing
We validate translations, layouts, currencies, date and number formats, and locale-specific functionality across supported regions.
