Problem Statement: Build an Online Open Code Editor Platform

Description

You are tasked with implementing the core logic of an online open code editor platform used to evaluate a candidate’s programming skills under time-restricted and controlled conditions.

The platform supports two primary user roles: Admin and Candidate.

Your Task

Implement a simulation for the Candidate and Admin workflows with the following behaviors:

---

Candidate Workflow (Simulated)

1. Landing Page

   • Displays test instructions (if any) and a Start Test button. (Refer to mockups for finalized details).
   • This page sets the context for the test and may include guidelines or disclaimers.
   • On clicking 'Start Test', the countdown timer is initiated and the candidate is taken to the test interface.

2. Editor/Test Page

   • Show a problem statement in markdown format (non-editable).
     • Ensures the candidate cannot alter or manipulate the problem definition during the test.
   • Provide a code editor:
     • Supports manual code typing and proper indentation.
     • Disables clipboard paste events to prevent copying from external sources, encouraging originality.
     • Tracks tab/window changes and logs them to detect focus shifts which may suggest cheating attempts.
   • Provide a console to:
     • Run the code against predefined test cases on the server.
     • Display output, errors, and pass/fail status of test cases.
   • A countdown timer enforces the test duration strictly.
     • Once time expires, the code editor and console are locked.
   • Auto-submits the candidate's code and records final results once the timer ends.

3. Finished Page

   • Displays a “Thank you” message to indicate the end of the test.
   • All interactions are disabled, and the user can no longer view or edit their code.

Admin Workflow (Simulated)

1. Login Panel

   • Admin logs in securely to access the admin panel for test management.
   • Authentication ensures only authorized personnel can modify test content or access candidate data.

2. Admin Panel

   • Admin can perform the following actions:
     • Create a new test with configurable options:
       • A clearly written problem statement in Markdown for formatting flexibility and readability.
       • A configurable test duration (e.g., 15, 30, 45 minutes).
       • Input/output test cases including both sample (visible to the candidate) and hidden (used for final evaluation) in JSON(preferably).
     • Monitor candidate activity logs:
       • Logs include tab switches, code run events, and auto-submission time to track behaviors.
     • Access results after test completion:
       • Review submitted code and output from candidates.
       • Generate reports if needed.(Optional)
     • Manage language support:
       • Enable or disable supported programming languages (e.g., Python, Java, Go) as required.
