My contribution

Automated REST APIs and reduced manual UI and data-validation testing using Java-based test automation with Serenity BDD, Cucumber, Cypress, and Selenium WebDriver within a Jenkins CI pipeline.

Simplified architecture

Simplified: Java-based BDD test suites (Serenity BDD, Cucumber, Cypress, Selenium WebDriver) automate REST API, UI, and data-validation checks within a Jenkins CI pipeline.

Outcomes

  • Automated approximately 20 REST APIs.
  • Reduced testing cycle time by approximately 40 percent.
  • Achieved approximately 95 percent code coverage.
  • Reduced post-release API-related defects by approximately 30 percent.
  • Reduced manual UI testing effort by approximately 80 percent.
  • Increased sprint velocity by approximately 25 percent.
  • Reduced manual data input by approximately 99 percent.
  • Reduced data-related defects by approximately 70 percent.
  • Improved data-processing throughput by approximately 300 percent.
