Overview

This is the core test runner module of @git.zone/tstest. It provides the CLI, test discovery, multi-runtime execution, TAP output parsing, structured logging, and test orchestration. It ties together the entire testing pipeline — from finding test files to dispatching them across Node.js, Chromium, Deno, Bun, and Docker runtimes.

Key Features

• 🔍 Smart Test Discovery — Glob patterns, directory scanning, and single-file mode
• 🏃 Multi-Runtime Execution — Node.js, Chromium, Deno, Bun, and Docker adapters
• 📊 TAP Protocol Parsing — Full Protocol V2 support with structured metadata
• 🎨 Rich Logging — Color-coded output, JSON mode, per-file log files, diff tracking
• ⚡ Parallel Execution — File-level parallel groups via *.para__N.* naming
• 👀 Watch Mode — Re-run tests on file changes with debouncing
• 🏷️ Tag Filtering — Run only tests matching specific tags
• ⏱️ Timeout Management — Per-file timeouts with process tree termination
• 📝 Test File Directives — Inline comments to configure runtime permissions and flags
• 🔄 Before Scripts — package.json-based lifecycle hooks (test:before, test:before:testfile)
• 🐳 Docker Testing — Run tests inside Docker containers via *.docker.sh files
• 🔀 Legacy Migration — Automatic rename of .browser.ts → .chromium.ts patterns

Architecture

Runtime Adapter System

Each runtime is implemented as a RuntimeAdapter with a unified interface:

Adapter	Runtime	How It Executes Tests
NodeRuntimeAdapter	Node.js	Spawns via @git.zone/tsrun, streams TAP output
ChromiumRuntimeAdapter	Chromium	Bundles with esbuild, serves over HTTP, communicates via WebSocket
DenoRuntimeAdapter	Deno	Runs deno run with configurable permissions
BunRuntimeAdapter	Bun	Runs bun run with auto-discovered config
DockerRuntimeAdapter	Docker	Builds image from Dockerfile, runs docker run

Test File Naming Convention

Test filenames determine which runtime(s) execute them:

Pattern	Runtimes
*.ts	Node.js (default)
*.node.ts	Node.js only
*.chromium.ts	Chromium browser
*.deno.ts	Deno
*.bun.ts	Bun
*.all.ts	All runtimes
*.node+chromium.ts	Node.js + Chromium
*.para__N.ts	Parallel group N
*.docker.sh	Docker container

Execution Flow

1. Discovery — TestDirectory scans for test files based on mode (directory/file/glob)
2. Grouping — Files are split into serial and parallel groups (via *.para__N.* naming)
3. Before Scripts — test:before / test:before:testfile from package.json run
4. Dispatch — Each file is parsed for runtime specifiers and directives, then routed to the appropriate RuntimeAdapter
5. Parsing — TapParser processes TAP output using Protocol V2, tracking results and events
6. Aggregation — TapCombinator merges results from all test files
7. Reporting — TsTestLogger outputs structured results (console, JSON, or log files)

Inline Directives

Test files can include comment directives at the top (before imports) to configure runtime behavior:

// tstest:deno:allowAll
// tstest:node:flag:--max-old-space-size=4096
// tstest:env:MY_VAR=value
import { tap, expect } from '@git.zone/tstest/tapbundle';

Directives in 00init.ts files apply to all tests in that directory and are merged with per-file directives.

CLI Usage

# Directory mode — scan recursively for test files
tstest test/

# File mode — run a single test
tstest test/test.math.ts

# Glob mode — match patterns
tstest "test/**/*.node.ts"

Options

Flag	Description
--verbose, -v	Show all console output from tests
--quiet, -q	Minimal output for CI
--json	Machine-readable JSON output
--logfile	Write per-file logs to .nogit/testlogs/
--tags <tags>	Filter tests by comma-separated tags
--timeout <sec>	Per-file timeout in seconds
--startFrom <n>	Start from file number N
--stopAt <n>	Stop at file number N
--watch, -w	Re-run tests on file changes
--watch-ignore <pat>	Comma-separated ignore patterns
--no-color	Disable ANSI colors

Public API

import { runCli, TestExecutionMode } from '@git.zone/tstest';

Export	Type	Description
runCli()	async function	CLI entry point — parses process.argv and runs tests
TestExecutionMode	enum	DIRECTORY, FILE, or GLOB
