We provide
Development Services
Manual Testing Services
Exploring every potential edge-case bug is critical for a stable product. Our QA team dives into manual testing, simulating real-user behavior across platforms to uncover hidden defects before release, ensuring consistency in functionality and usability.
Test Case Design & Test Planning
We build precise test strategies using tools like Qase.io, defining clear test cases and structured plans that map to your app’s requirements. This approach ensures comprehensive feature coverage, effective test execution, and traceable results.
Automated Testing Services
Leveraging Selenium, Selenide, and Java, we create automated test suites that execute repetitive checks reliably and fast. This strengthens regression control, boosts efficiency, and helps your team release with confidence.
Performance & Load Testing
By simulating stress testing scenarios with JMeter, we identify performance bottlenecks and load thresholds under high concurrency. Our diagnostics ensure your apps deliver solid performance even under heavy user loads.
Security Testing
Applying OWASP standards, we conduct thorough scans for XSS, SQL injection, CSRF, and other vulnerabilities. Our goal is to reinforce your application’s security, mitigate risk, and ensure regulatory compliance.
Usability & UX Testing
We evaluate user journeys, navigation, and interface clarity through user flow validation, ensuring your product is intuitive, engaging, and provides a top-tier customer experience.
API Testing
Focusing on both RESTful and SOAP API, we utilize Postman and SoapUI to validate endpoints, check data integrity, handle error scenarios, and support integration quality across services.
Cross‑Browser & Cross‑Platform Testing
Through cloud platforms (e.g., LambdaTest), we test in Chrome, Firefox, Safari on Windows, macOS, Android, and iOS—catching browser‑specific bugs and delivering a consistent experience.
Continuous Testing in CI/CD Pipelines
We integrate shift-left testing into CI/CD using Bitbucket Pipelines or GitHub workflows, enabling early defect detection and improving code quality throughout development cycles.
QA Consulting & Strategy Development
Our specialists work closely with your team to assess processes, build TDD/BDD frameworks, define quality KPIs, and lay out a robust quality assurance roadmap tailored to your enterprise objectives.
Bug Tracking & Reporting
Using YouTrack and Linear, we streamline bug reporting and test-task alignment, offering transparent workflows and ensuring all defects are tracked, prioritised, and resolved collaboratively.
Quality Metrics & Test Coverage Analysis
We leverage metrics to assess coverage, defect density, and test effectiveness—enabling data-driven QA decisions that enhance your digital product’s reliability.
