SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pyte.

What problem does it solve?

This skill ensures the reliability of terminal-based user interfaces by automating end-to-end testing of rendering, keypress latency, and visual correctness under a pseudo-terminal environment.

Core Features & Use Cases

Rendering Validation: Compares TUI output against a stock renderer to detect regressions in colors, layout, and glyph alignment.
Performance Benchmarking: Measures keypress latency and output volume to ensure a responsive user experience.
Edge Case Testing: Validates complex behaviors like threaded comment nesting, link styling, and tab navigation boundaries.

Quick Start

Run the tui-validate skill to execute the full suite of end-to-end rendering and latency checks against the current build.

FAQPage Schema

How do I validate terminal user interface rendering and keypress latency?▼

Terminal user interface rendering and keypress latency are validated by running a test suite against a pyte-emulated screen and pseudo-terminal harness to detect visual regressions and measure performance.

What is the best way to automate TUI performance benchmarking and visual consistency checks?▼

TUI performance benchmarking and visual consistency checks are automated by comparing output against a stock renderer to detect layout regressions, measure keypress latency, and validate ANSI escape sequence handling.

Does pyte support high-fidelity ANSI escape sequence testing for terminal applications?▼

Yes, pyte supports high-fidelity ANSI escape sequence testing by emulating a screen environment within a pseudo-terminal harness to verify colors, glyph alignment, and threaded comment nesting.

Do I need a .NET SDK to run terminal rendering validation?▼

Yes, a .NET SDK is required to execute the application harness against the simulated backend, alongside a Python environment with pyte for terminal emulation and latency measurement.

What terminal edge cases can I test with a pyte-emulated screen?▼

A pyte-emulated screen tests terminal edge cases including link styling, tab navigation boundaries, threaded comment nesting, and glyph alignment to ensure visual output consistency under complex conditions.

Can I use tui-validate to detect visual regressions in terminal colors and layout?▼

Yes, tui-validate detects visual regressions in terminal colors and layout by comparing TUI output against a stock renderer within a pseudo-terminal environment to ensure rendering fidelity.
