David Snelling 94c88e128c **docs: remove outdated statistics-related documentation and add standards**

- **Removed Files**:
  - Deleted outdated statistics documentation files (`statistics.md`, `statistics-flush-solution.md`, `statistics-summary.md`) to clean up the repository and avoid confusion.

- **Added Standards**:
  - Introduced `DOCUMENTATION_STANDARDS.md` to outline naming conventions and troubleshooting practices for more consistent and maintainable project documentation.

- **Tests**:
  - Added a new test file `edge-cases.test.ts` to verify handling of edge cases, ensuring robust behavior against boundary values and invalid inputs.

**Purpose**: Cleans up deprecated documentation while introducing concrete standards for maintaining and updating documentation. Enhances test coverage for unusual or boundary inputs, improving overall system resilience.

Pretty Test Reporter for Brainy

This document describes the visually enhanced test reporter added to the Brainy project.

Overview

The Pretty Test Reporter provides a visually appealing summary of test results with colors, symbols, and formatted output. It enhances the standard Vitest output with a clear, easy-to-read summary at the end of test runs.

Features

🎨 Colorful Output: Uses colors to distinguish between passed, failed, and skipped tests
📊 Tabular Format: Displays test results in a clean, tabular format
📝 Detailed Summary: Shows overall test statistics and file-by-file breakdown
❌ Error Reporting: Clearly lists any failed tests with their error messages
⏱️ Timing Information: Displays test duration in a human-readable format

Usage

To run tests with the pretty reporter, use the following npm script:

npm run test:report:pretty

You can also specify specific test files:

npm run test:report:pretty -- tests/core.test.ts

Example Output

Implementation Details

The pretty reporter is implemented as a custom Vitest reporter in src/testing/prettySummaryReporter.ts. It:

Collects test information during the test run
Tracks passed, failed, and skipped tests
Organizes results by test file
Generates a formatted summary at the end of the test run

Configuration

The reporter is configured in vitest.config.ts and works alongside the default Vitest reporter and JSON reporter. This provides both the standard output during test execution and the enhanced summary at the end.

Customization

If you need to modify the reporter's appearance or behavior, you can edit the prettySummaryReporter.ts file. The main visual elements are in the printSummary method.
