PR Summary

• New Workflow for Frontend Tests
  A new GH Actions workflow is introduced to conduct tests for the frontend code whenever a pull request is triggered. This workflow includes checking code, installing dependencies, linting, running tests, and creating coverage reports.

• Dockerfile Revisions
  We have made necessary adjustments to the Dockerfile used for running the frontend. Now it excludes development dependencies, making it more efficient and suited for production environments.

• Dependencies Streamlining
  The dependencies arrangement in the project has been improved for better organization. These changes make it easier to distinguish between main and development dependencies, thus simplifying project management.

• Introduction of pytest fixtures
  Our testing has been enhanced through the use of pytest fixtures. These assist in capturing rendered templates during tests, which increases the reliability and accuracy of our tests.

• Added Tests for Frontend
  AMore comprehensive tests have been added to check the entire functionality of the frontend application. These tests include checks for rendering pages, validating the addition of sessions, and checking the health status of the app. These additions ensure application robustness and help maintain high-quality standards.
