Testing coverage for web, mobile, and ecommerce platforms
Types of software testing we deliver
We structure our software testing services around real project needs, not testing philosophy. Here’s what we test and when each testing type matters:
Functional testing
Functional testing evaluates whether each function of your software application works according to specified requirements. This testing verifies that features produce correct outputs when given specific inputs, without examining the underlying code structure—focusing entirely on what the software does, not how it does it.
We test user-accessible features, entry and exit points, data processing, error handling, and business logic validation. Functional testing covers user workflows from start to finish, ensuring login systems authenticate correctly, forms validate input properly, calculations produce accurate results, and workflows complete as designed. This testing catches defects that would directly impact users’ ability to accomplish their intended tasks.
UI/UX testing
UI/UX testing evaluates your application from the user’s perspective, verifying that the user interface behaves correctly and that the system delivers an intuitive, accessible experience. This testing checks that layout, navigation, visual elements, and interactive components function as intended and meet user expectations across browsers and devices.
We verify that buttons, menus, and forms respond correctly to user actions, validate visual consistency across screen sizes, test navigation flows for logical progression, and confirm accessibility compliance for keyboard navigation and screen readers. UI/UX testing catches issues like misaligned elements, confusing workflows, broken responsive design, and inconsistent visual presentation—problems that damage user satisfaction even when underlying functionality works correctly.
Integration testing
Integration testing validates that different modules or systems communicate correctly. When your website exchanges data with a CRM, connects to payment processors, or pulls inventory from backend systems, integration testing confirms those connections work as designed.
We test data flow between systems, API responses under various conditions, authentication handshakes, error handling when external services fail, and edge cases where timing or data formats could create problems.
Real example: testing that product inventory syncs correctly between your webshop and ERP system—handling stock updates, price changes, product variants, and ensuring orders flow accurately between systems while maintaining data consistency.
Regression testing
Regression testing verifies that new code changes haven’t broken existing functionality. Every time the development team adds features, fixes bugs, or updates dependencies, regression testing confirms nothing unexpected broke in the process.
We run regression testing after each deployment cycle, focusing on critical user paths, payment processing, data integrity, and integration points. For established applications with frequent updates, we implement automated regression testing that runs on schedule—catching issues before they reach production and reducing the manual testing burden as your codebase grows.
Smoke testing
Smoke testing is a rapid verification that core functionality still works after builds or deployments. Think of it as a quick health check—can users log in, do critical workflows complete, are payment processes functioning, does data save correctly?
We run smoke testing after every deployment to catch obvious breaks immediately, before more comprehensive testing begins. If smoke testing fails, we halt further testing until the issue gets resolved. Smoke testing is often automated to save time and speed up new deployments, allowing faster release cycles without sacrificing quality verification.
API testing
API testing verifies that application programming interfaces function correctly according to specifications. This testing validates that data exchanges properly between systems, responses return accurate and timely information, error handling works as intended, and security mechanisms protect against unauthorized access.
We test API endpoints for correct responses under various conditions, verify data format accuracy (JSON, XML), validate authentication and authorization logic, check response times under load, and confirm that APIs handle edge cases and failures appropriately. API testing matters particularly for applications that integrate with payment processors, CRMs, inventory systems, or any external services—ensuring these critical connections work reliably before users depend on them.
Load testing
Load testing simulates realistic user traffic to identify performance bottlenecks before they impact real users. We test how your application performs under expected peak loads, measure response times as concurrent users increase, identify database queries that slow down under pressure, and pinpoint infrastructure constraints before launch.
This testing matters most for applications expecting traffic spikes—product launches, seasonal sales, marketing campaigns, or applications where performance directly impacts conversion rates.
Performance testing
Performance testing measures page load times, resource optimization, and overall performance from a user perspective. We test desktop and mobile load times, identify images or scripts slowing page renders, measure time to interactive, and validate that caching and compression work correctly.
Fast sites convert better. Speed testing ensures performance meets user expectations before launch.
Security testing
Security testing identifies vulnerabilities that could compromise data, expose user information, or create compliance issues. Our security testing focuses on checking that CMS security patches apply correctly, validating authentication and authorization logic, testing for common vulnerabilities in custom code, and ensuring sensitive data transmits and stores securely.
Note: Our security testing covers application-level vulnerabilities and CMS patch verification. For comprehensive penetration testing or security audits, we recommend working with specialized security firms.
User acceptance testing (UAT)
User acceptance testing validates that software meets actual user requirements before launch. UAT happens after development completes and focuses on real-world workflows, business process validation, and whether the software solves the problem it was built to solve.
We facilitate UAT by setting up testing environments, creating test scenarios based on user stories, documenting issues in language stakeholders understand, and coordinating between technical teams and business owners to resolve concerns before go-live.
Internationalization and localization testing
For software serving multiple regions or languages, internationalization and localization testing validates that formatting, character sets, and cultural expectations work correctly across markets.
We test character rendering across languages, date and time format displays, currency symbols and number formatting, address and phone number field validation, government number formats (CVR, Social Security, etc.), and whether content layout adapts to right-to-left languages when needed.
Why our testing approach improves project outcomes
Experienced software testers
We've tested thousands of projects across industries, platforms, and technologies. That experience matters when evaluating edge cases, anticipating integration problems, and knowing which tests provide value.
Dedicated QA teams, not developer testing
Our QA testers focus exclusively on finding issues. They think like users, not like the developers who built the features. That perspective catches problems developers miss because they're too close to the code.
Manual and automated testing expertise
We know when to use which approach and how to combine both for optimal coverage. You don't get automated testing forced onto projects where manual testing works better, or vice versa.
24-hour typical support turnaround
For ongoing clients, reported issues typically get resolved within 24 hours. Bug fixes and updates don't wait days or weeks.

Commonly asked questions
Which types of testing does my project actually need?
All projects need functional testing (verifying features work correctly) and UI/UX testing (ensuring usable interface). Add regression testing if you have frequent updates or existing functionality that must stay working. Include integration testing if you connect to payment processors, CRMs, inventory systems, or external APIs. Use load testing for applications expecting traffic spikes or where performance impacts conversions. Security testing matters for applications handling sensitive data. The specific combination depends on your project risk, complexity, and user expectations.
Can you provide testing services for projects we're developing internally, or only for projects you build?
We provide standalone QA testing services where our testing team works alongside your development team. You don’t need to use 1902 Software for development to access our testing expertise. We integrate with your workflow—receiving builds, running test scenarios, reporting issues in your tracking system, coordinating with your developers for fixes. Many clients use us for testing while maintaining their own development teams.
How does testing fit into the development timeline—when does it happen?
Testing happens at multiple stages. Early involvement: QA reviews specifications before development to catch usability issues and missing functionality when changes are cheap. Design review: QA examines mockups before development starts. Core testing phase: after development completes, QA runs comprehensive testing on staging servers before launch. Ongoing testing: after launch, QA tests updates, new features, and performs regression testing to ensure system stability. Testing is continuous throughout the project lifecycle, not just a final pre-launch activity.
What platforms and technologies can you test?
We test WordPress, Magento, WooCommerce, Shopify, Umbraco, custom .NET applications, PHP-based systems, React frontends, mobile apps (iOS/Android), progressive web applications, and API integrations. Our QA teams have experience across diverse technologies and adapt testing approaches to your technical stack. If you’re using a platform we don’t actively develop on, we’ll be honest about whether we can provide effective testing for it.
What's included in your typical testing turnaround and support response times?
For ongoing clients with support agreements, reported issues typically get resolved within 24 hours. Bug fixes and updates don’t wait days or weeks. Testing timeline for new features depends on complexity—simple features may complete testing in 1-2 days, complex features with integrations take 3-5 days for thorough validation. We provide specific timeline estimates during project planning based on scope and testing requirements.
