Testing HTTPS Request Security Detection in Koa.js

This test suite evaluates the secure request functionality in Koa.js, specifically testing the req.secure property that determines if a request is made over HTTPS. The tests verify the correct detection of encrypted socket connections to ensure proper security status reporting.

Test Coverage Overview

The test coverage focuses on the fundamental security detection mechanism in Koa.js requests.

Tests the req.secure property determination
Verifies encrypted socket detection
Validates boolean return values for security status

Implementation Analysis

The testing approach employs Jest’s describe/it blocks for structured test organization. The implementation uses Node’s built-in test framework with strict assertion checking.

Uses mock request objects with simulated socket properties
Implements socket encryption simulation
Employs strict equality assertions

Technical Details

Node.js test framework integration
Custom test helpers for context creation
Assert module for validation
Mock socket object manipulation
Strict mode JavaScript execution

Best Practices Demonstrated

The test suite exemplifies clean and focused testing practices with clear separation of concerns.

Single responsibility principle in test cases
Clear test descriptions
Proper test isolation
Effective use of test helpers
Minimal test setup complexity
