WORKFLOW: Enforce Supertest Workflow on Feature Branches Before Merge

[agaesh]

Description:
We need to implement a CI pipeline that ensures all feature branches are tested using Supertest before they can be merged into the main branch. This will help maintain code quality and prevent breaking changes.

Requirements:

• Set up a GitHub Actions workflow triggered on pull requests to the main branch.
• Run all Supertest test cases automatically.
• Block the merge if any test case fails.
• Provide a summary report of test results in the PR.
• Ensure the workflow can be extended for future testing frameworks.

Expected Outcome:
All feature branches must pass automated tests before merging, improving stability and reducing regressions.
