✨ Key Features

🎯 Smart Test Execution - Run all tests, single files, or use glob patterns
🎨 Beautiful Output - Color-coded results with emojis and clean formatting
📊 Multiple Output Modes - Choose from normal, quiet, verbose, or JSON output
🔍 Automatic Discovery - Finds all your test files automatically
🌐 Cross-Environment - Supports Node.js and browser testing
📝 Detailed Logging - Optional file logging for debugging
⚡ Performance Metrics - See which tests are slow
🤖 CI/CD Ready - JSON output mode for automation

Installation

npm install --save-dev @gitzone/tstest
# or with pnpm
pnpm add -D @gitzone/tstest

Usage

Basic Test Execution

# Run all tests in a directory
tstest test/

# Run a specific test file
tstest test/test.mycomponent.ts

# Use glob patterns
tstest "test/**/*.spec.ts"
tstest "test/unit/*.ts"

Execution Modes

tstest intelligently detects how you want to run your tests:

Directory mode - Recursively finds all test files
File mode - Runs a single test file
Glob mode - Uses pattern matching for flexible test selection

Command Line Options

Option	Description
`--quiet`, `-q`	Minimal output - perfect for CI environments
`--verbose`, `-v`	Show all console output from tests
`--no-color`	Disable colored output
`--json`	Output results as JSON
`--logfile`	Save detailed logs to `.nogit/testlogs/[testname].log`

Example Outputs

Normal Output (Default)

🔍 Test Discovery
   Mode: directory
   Pattern: test
   Found: 4 test file(s)

▶️  test/test.ts (1/4)
   Runtime: node.js
   ✅ prepare test (1ms)
   Summary: 1/1 PASSED

📊 Test Summary
┌────────────────────────────────┐

└────────────────────────────────┘

ALL TESTS PASSED! 🎉

Quiet Mode

Found 4 tests
✅ test functionality works
✅ api calls return expected data
✅ error handling works correctly
✅ performance is within limits

Summary: 4/4 | 542ms | PASSED

Verbose Mode

Shows all console output from your tests, making debugging easier:

▶️  test/api.test.ts (1/1)
   Runtime: node.js
   Making API call to /users...
   Response received: 200 OK
   Processing user data...
   ✅ api calls return expected data (145ms)
   Summary: 1/1 PASSED

JSON Mode

Perfect for CI/CD pipelines:

{"event":"discovery","count":4,"pattern":"test","executionMode":"directory"}
{"event":"fileStart","filename":"test/test.ts","runtime":"node.js","index":1,"total":4}
{"event":"testResult","testName":"prepare test","passed":true,"duration":1}
{"event":"summary","summary":{"totalFiles":4,"totalTests":4,"totalPassed":4,"totalFailed":0,"totalDuration":542}}

Test File Naming Conventions

tstest supports different test environments through file naming:

Pattern	Environment	Example
`*.ts`	Node.js (default)	`test.basic.ts`
`*.node.ts`	Node.js only	`test.api.node.ts`
`*.chrome.ts`	Chrome browser	`test.dom.chrome.ts`
`*.browser.ts`	Browser environment	`test.ui.browser.ts`
`*.both.ts`	Both Node.js and browser	`test.isomorphic.both.ts`

Writing Tests

tstest uses TAP (Test Anything Protocol) for test output. Use @pushrocks/tapbundle for the best experience:

import { expect, tap } from '@push.rocks/tapbundle';

tap.test('my awesome test', async () => {
  const result = await myFunction();
  expect(result).toEqual('expected value');
});

tap.start();

Advanced Features

Glob Pattern Support

Run specific test patterns:

# Run all unit tests
tstest "test/unit/**/*.ts"

# Run all integration tests
tstest "test/integration/*.test.ts"

# Run multiple patterns
tstest "test/**/*.spec.ts" "test/**/*.test.ts"

Automatic Logging

Use --logfile to automatically save test output:

tstest test/ --logfile

This creates detailed logs in .nogit/testlogs/[testname].log for each test file.

Performance Analysis

In verbose mode, see performance metrics:

⏱️  Performance Metrics:
   Average per test: 135ms
   Slowest test: api integration test (486ms)

CI/CD Integration

For continuous integration, combine quiet and JSON modes:

# GitHub Actions example
tstest test/ --json > test-results.json

# Or minimal output
tstest test/ --quiet
