Quality Assurance

Quality Assurance (QA) is integral to The One X Methodology, ensuring that software meets the highest standards of functionality, reliability, and user experience. Our comprehensive QA approach combines automated testing, manual validation, and continuous monitoring.

QA Philosophy​

Prevention Over Detection​

  • Shift-Left Testing: Integrate quality checks early in the development process
  • Design for Testability: Build applications with testing in mind from the start
  • Continuous Validation: Validate quality at every stage of development

Comprehensive Coverage​

  • Functional Testing: Ensure features work as designed
  • Non-Functional Testing: Performance, security, usability, and accessibility
  • Cross-Platform Testing: Validate across different browsers, devices, and environments

QA Process Framework​

1. Requirements Analysis​

QA Involvement in Planning

  • Review requirements for testability
  • Identify potential edge cases and scenarios
  • Define acceptance criteria with development team
  • Create test strategy document

Risk Assessment

  • Identify high-risk areas requiring additional testing
  • Evaluate impact of potential failures
  • Prioritize testing efforts based on business value

2. Test Planning and Design​

Test Strategy Development​

Test Levels

  • Unit Testing: Developer-driven component testing
  • Integration Testing: API and service integration validation
  • System Testing: End-to-end functionality validation
  • Acceptance Testing: Business requirement validation
