Our Web App Testing Workflow

  • Planning

    We analyze your requirements, define test scenarios, design test cases, and establish testing strategies.

  • Test Execution

    Utilizing automated and manual techniques, we perform functional, usability, compatibility, security, and performance testing.

  • Defect Tracking & Handling

    We log and prioritize bugs (via Jira, Bugzilla, MantisBT, and GitHub Issues) and work with developers to manage defects.

  • Reporting & Maintenance

    We provide detailed test reports, recommend improvements, and offer post-deployment support.


We prioritize data security and compliance through rigorous measures like data encryption, secure test environments, access controls, and adherence to industry standards (e.g., GDPR, HIPAA). Additionally, we regularly audit our processes and provide comprehensive training to our team on secure data handling and regulatory compliance.

We maintain open and transparent communication through regular status meetings, collaborative tools (Slack, Skype, Zoom, etc), and shared documentation. As a dedicated point of contact, our project manager facilitates seamless collaboration with your development team.

We primarily use Selenium for web app testing due to its flexibility, cross-browser compatibility, and robust community support. However, we evaluate each project's specific requirements (e.g., technology stack, testing needs) and may recommend alternative frameworks like Cypress, Appium, or TestNG when appropriate.

Automation scripts undergo continuous maintenance and version control using Git or similar tools. We have a defined process for refactoring and updating scripts to accommodate application changes, ensuring our automation test suite remains up-to-date and reliable.
