How would you approach integrating accessibility testing into a DevOps pipeline?

I would incorporate automated accessibility testing tools such as Axe or Lighthouse into the CI/CD pipeline. This ensures that accessibility issues are identified early in the development process and can…

🏷️
How would you design a testing strategy for a microservices architecture that ensures each service is thoroughly tested while also considering integration testing across service boundaries?

I would implement a layered testing approach, including unit tests for each service, contract tests to validate interactions between services, and end-to-end tests for critical user flows. This ensures that…
