Environment

  • Ruby: 3.4.8 (MSVC)
  • Platform: Windows 10 (64-bit)
  • Date: December 23, 2025

1. Functional Test Suite

The functional test suite covers core components: Color, Style, Text, Markup, Console, Box, Table, Trees, Progress, Syntax, Markdown, and JSON.

Command:

ruby -W0 -Ilib -Itest -e "require './test/test_helper'; Dir['test/test_*.rb'].each { |f| require File.expand_path(f) }"

Results:

Run options: --seed 29775

# Running:

.......................................................................................
───────────────────────────────── Title ───────────────────────────────────────────────
...Hello
..................................................................................................

Finished in 0.041029s, 4582.0690 runs/s, 8432.9568 assertions/s.

188 runs, 346 assertions, 0 failures, 0 errors, 0 skips

2. Performance & Stress Test Suite

The stress test suite validates the library under heavy load and deep nesting conditions.

Command:

ruby -W0 -Ilib examples/stress_test.rb
