Code Deployment Verification Information


Verifying code deployment in a pre-production environment involves checking both the frontend and backend components to ensure that the deployment was successful and that the application functions as expected. Here are some points to consider for both frontend and backend verification:


Frontend Code Deployment:


  1. UI/UX Consistency:

    • Verify that the user interface looks consistent with the design and previous versions.
    • Check for any layout issues, font rendering problems, or broken styles.

  2. Functionality:

    • Test critical functionalities of the frontend to ensure they work as expected.
    • Verify that user interactions, such as clicks and form submissions, produce the intended results.

  3. Browser Compatibility:

    • Test the application on different browsers (e.g., Chrome, Firefox, Safari, Edge) to ensure compatibility.
    • Check for responsiveness on various devices (desktop, tablet, mobile).

  4. Performance:

    • Assess the frontend performance, including page load times and responsiveness.
    • Identify and address any performance bottlenecks.

  5. Console Errors and Warnings:

    • Check the browser console for any errors or warnings that may indicate issues with the frontend code.
    • Resolve or report any errors found during testing.

  6. Integration with APIs:

    • If the frontend relies on APIs, verify that the integration is functioning correctly.
    • Ensure that data is fetched and displayed accurately.


Backend Code Deployment:


  1. API Endpoints:

    • Confirm that all API endpoints are accessible and responding correctly.
    • Test different API methods (GET, POST, PUT, DELETE) with appropriate input parameters.

  2. Database:

    • Verify that the database schema has been updated successfully if there were any changes.
    • Test database connections and ensure that data is being stored and retrieved properly.

  3. Security:

    • Check for security vulnerabilities, such as SQL injection or cross-site scripting (XSS).
    • Ensure that access controls and authentication mechanisms are functioning correctly.

  4. Logs and Monitoring:

    • Review backend logs for any errors or warnings.
    • Ensure that monitoring systems are in place to detect anomalies or performance issues.

  5. Scalability:

    • Assess the system’s scalability by simulating a reasonable amount of load.
    • Check if the application can handle concurrent users and requests.

  6. Configuration Settings:

    • Confirm that all configuration settings for the backend services are correctly applied.
    • Check environment-specific configurations for the pre-production environment.

  7. Rollback Plan:

    • Ensure that a rollback plan is in place in case any critical issues are identified after deployment.
    • Test the rollback process to make sure it works as intended.

  8. Documentation:

    • Update any relevant documentation to reflect changes made during the deployment.
    • Ensure that documentation is accessible to the team for reference.


By systematically verifying these aspects of both frontend and backend code, you can increase the likelihood of a successful deployment in the pre-production environment. It’s also crucial to involve relevant stakeholders, such as QA teams, during the verification process.
