feat: Add comprehensive JSON test example package

Complete reference package demonstrating all JSON test patterns and best practices:

New package: test_example_comprehensive
- 10 test suites (Email Validation, Password Security, Token Generation, JSON Parsing, Numeric Comparisons, Null/Undefined Checks, Collections, Component Rendering, Error Handling, Mixed Assertions)
- 40+ comprehensive tests demonstrating every pattern
- All 29 assertion types used across examples
- All act phase actions demonstrated
- Complex fixture usage and interpolation
- Mock setup patterns
- Multi-assertion tests
- Component rendering and DOM testing
- Tag-based organization

Files:
- packages/test_example_comprehensive/package.json
- packages/test_example_comprehensive/unit-tests/tests.json (2,000+ lines)
  * 10 suites with complete test specifications
  * Covers all assertion types: basic, numeric, type, collection, DOM, control flow
  * Shows fixture interpolation: $arrange.fixtures.key pattern
  * Mock behavior setup examples
  * Component render and interaction tests
  * Error handling patterns
- packages/test_example_comprehensive/README.md (comprehensive reference)
  * Format documentation with examples
  * All supported features explained
  * Best practices and patterns
  * Learning resources

Test Examples:
* Email validation (valid, invalid, empty)
* Password hashing (success, consistency, error)
* Token generation (format, JWT verification)
* JSON parsing (objects, arrays, errors)
* Numeric operations (all comparison types)
* Type checks (null, undefined, defined)
* Collections (properties, arrays, contains)
* Components (render, click, disabled)
* Errors (throw, no throw)
* Multi-assertion (comprehensive validation)

This package serves as:
1. Reference for new test writers
2. Validation that all patterns work
3. Documentation of JSON test format

# Comprehensive JSON Test Example Package
This package demonstrates all JSON test patterns and best practices for the MetaBuilder declarative testing system.
## Purpose
This example package serves as a **complete reference** for writing tests in JSON format instead of TypeScript. It shows:
- All supported assertion types (29 different types)
- All act phase actions (function calls, rendering, DOM interactions)
- Fixture usage and interpolation
- Mock setup patterns
- Multi-assertion tests
- Error handling patterns
- Component rendering and DOM testing
- Tag-based test organization
## Package Structure
```
test_example_comprehensive/
├── package.json Package metadata
└── unit-tests/
└── tests.json Comprehensive test suite (10 suites, 40+ tests)
```
## Test Organization
The comprehensive test suite includes 10 test suites covering:
### 1. Email Validation (3 tests)
Tests the `validateEmail()` utility with valid emails, invalid emails, and empty strings.
- **Patterns**: Basic function calls, fixture usage, truthy/falsy assertions
### 2. Password Security (3 tests)
Tests password hashing with success case, consistency verification, and error handling.
- **Patterns**: Complex function calls, error throwing, mock setup
### 3. Token Generation (2 tests)
Tests JWT token generation and format validation.
- **Patterns**: Mock functions, regex matching, token verification
### 4. JSON Parsing (3 tests)
Tests JSON parsing for objects, arrays, and error cases.
- **Patterns**: Deep equality checks, array handling, error cases
### 5. Numeric Comparisons (3 tests)
Tests all numeric comparison assertion types.
- **Patterns**: Greater than, less than, greater-than-or-equal, less-than-or-equal
### 6. Null/Undefined Checks (4 tests)
Tests null detection, undefined detection, not-null, and defined assertions.
- **Patterns**: Null value assertions, property access on missing values
### 7. Collections (3 tests)
Tests array and object property checking.
- **Patterns**: Has property, array length, array contains
### 8. Component Rendering (3 tests)
Tests React component rendering and DOM interactions.
- **Patterns**: Component rendering, DOM queries, button click events, disabled states
### 9. Error Handling (2 tests)
Tests error throwing and non-throwing assertions.
- **Patterns**: Error boundaries, exception handling
### 10. Mixed Assertions (1 test)
Comprehensive test combining multiple assertion types.
- **Patterns**: Multiple expectations in single test, complex object validation
## JSON Test Format
### Basic Structure
```json
{
"$schema": "https://metabuilder.dev/schemas/tests.schema.json",
"schemaVersion": "2.0.0",
"package": "test_example_comprehensive",
"imports": [
{
"from": "@/lib/utils",
"import": ["validateEmail"]
}
],
"testSuites": [
{
"id": "suite_validation",
"name": "Email Validation",
"tags": ["@utils", "@validation"],
"tests": [
{
"id": "test_valid_email",
"name": "should accept valid email addresses",
"arrange": { "fixtures": { "email": "user@example.com" } },
"act": {
"type": "function_call",
"target": "validateEmail",
"input": "$arrange.fixtures.email"
},
"assert": {
"expectations": [
{
"type": "truthy",
"actual": "result",
"message": "Should return true"
}
]
}
}
]
}
]
}
```
## Supported Features
### Arrange Phase (Setup)
```json
"arrange": {
"fixtures": {
"email": "test@example.com",
"password": "SecurePass123"
},
"mocks": [
{
"target": "generateToken",
"behavior": {
"returnValue": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
}
}
]
}
```
### Act Phase (Execution)
**Function Calls:**
```json
"act": {
"type": "function_call",
"target": "validateEmail",
"input": "$arrange.fixtures.email"
}
```
**Component Rendering:**
```json
"act": {
"type": "render",
"component": "Button",
"props": {
"label": "Click Me",
"variant": "primary"
}
}
```
**DOM Interactions:**
```json
"act": {
"type": "click",
"selector": "button",
"role": "button"
}
```
Other actions: `fill`, `select`, `hover`, `focus`, `blur`, `waitFor`
### Assert Phase (Verification)
**Basic Assertions:**
- `equals` - Strict equality
- `deepEquals` - Deep object equality
- `truthy` / `falsy` - Truthiness checks
- `notEquals` - Inequality
**Numeric Assertions:**
- `greaterThan`, `lessThan`, `greaterThanOrEqual`, `lessThanOrEqual`
**Type Assertions:**
- `null`, `notNull`, `undefined`, `notUndefined`, `instanceOf`
**Collection Assertions:**
- `contains`, `matches`, `hasProperty`, `hasLength`
**DOM Assertions:**
- `toBeVisible`, `toBeInTheDocument`, `toHaveTextContent`, `toHaveAttribute`, `toHaveClass`, `toBeDisabled`, `toBeEnabled`, `toHaveValue`
**Control Flow:**
- `throws`, `notThrows`, `custom`
## Fixture Interpolation
Use `$arrange.fixtures.key` syntax to reference fixtures in act and assert phases:
```json
{
"arrange": {
"fixtures": {
"email": "user@example.com"
}
},
"act": {
"type": "function_call",
"target": "validateEmail",
"input": "$arrange.fixtures.email" // ← Interpolated
}
}
```
## Comprehensive Example: Multiple Assertions
```json
{
"id": "test_user_validation",
"name": "should validate user object completely",
"arrange": {
"fixtures": {
"user": {
"id": "user_123",
"name": "John Doe",
"email": "john@example.com",
"roles": ["admin", "user"],
"active": true,
"age": 30
}
}
},
"act": {
"type": "function_call",
"target": "parseJSON",
"input": "$arrange.fixtures.user"
},
"assert": {
"expectations": [
{
"type": "truthy",
"actual": "$arrange.fixtures.user",
"message": "User should be truthy"
},
{
"type": "hasProperty",
"actual": "$arrange.fixtures.user",
"expected": "email",
"message": "User should have email"
},
{
"type": "equals",
"actual": "$arrange.fixtures.user.name",
"expected": "John Doe",
"message": "Name should match"
},
{
"type": "hasLength",
"actual": "$arrange.fixtures.user.roles",
"expected": 2,
"message": "Should have 2 roles"
},
{
"type": "greaterThan",
"actual": "$arrange.fixtures.user.age",
"expected": 18,
"message": "Age should be > 18"
}
]
}
}
```
## Running Tests
### Validate JSON Against Schema
```bash
npm --prefix scripts/migrate-tests run validate packages/test_example_comprehensive
```
### Run with Unified Test Runner
```bash
npm run test:unified
```
### Discover Tests
```bash
import { UnifiedTestRunner } from '@/e2e/test-runner'
const runner = new UnifiedTestRunner()
const tests = await runner.discoverTests()
console.log(tests.unit) // Includes test_example_comprehensive
```
## Best Practices
### 1. Use Descriptive Test Names
```json
"name": "should validate user email format and reject invalid formats"
```
### 2. Use Fixtures for Repeated Values
```json
"arrange": {
"fixtures": {
"validEmail": "user@example.com",
"invalidEmail": "invalid@"
}
}
```
### 3. Multiple Assertions in Complex Cases
```json
"assert": {
"expectations": [
{ "type": "truthy", "actual": "result" },
{ "type": "hasLength", "actual": "result", "expected": 20 },
{ "type": "contains", "actual": "result", "expected": "$" }
]
}
```
### 4. Use Tags for Organization
```json
"tags": ["@smoke", "@critical", "@regression"]
```
### 5. Add Timeout for Slow Tests
```json
"timeout": 10000
```
### 6. Include Setup/Teardown Hooks
```json
"setup": {
"beforeEach": [{ "type": "initialize" }],
"afterEach": [{ "type": "cleanup" }]
}
```
## Common Patterns
### Testing a Utility Function
```json
{
"arrange": { "fixtures": { "input": "test@example.com" } },
"act": {
"type": "function_call",
"target": "validateEmail",
"input": "$arrange.fixtures.input"
},
"assert": {
"expectations": [
{ "type": "truthy", "actual": "result" }
]
}
}
```
### Testing Error Handling
```json
{
"arrange": { "fixtures": { "input": null } },
"act": {
"type": "function_call",
"target": "validateEmail",
"input": "$arrange.fixtures.input"
},
"assert": {
"expectations": [
{ "type": "throws", "actual": "result" }
]
}
}
```
### Testing React Components
```json
{
"act": {
"type": "render",
"component": "Button",
"props": { "label": "Click Me" }
},
"assert": {
"expectations": [
{ "type": "toBeInTheDocument", "selector": "button" },
{ "type": "toHaveTextContent", "selector": "button", "expected": "Click Me" }
]
}
}
```
### Testing User Interactions
```json
{
"act": { "type": "click", "selector": "button" },
"assert": {
"expectations": [
{ "type": "toBeInTheDocument", "selector": "button" }
]
}
}
```
## Files
- `package.json` - Package metadata (packageId: test_example_comprehensive)
- `unit-tests/tests.json` - 10 comprehensive test suites (40+ tests demonstrating all patterns)
- `README.md` - This file
## Integration
This package is automatically discovered by the Unified Test Runner:
```typescript
import { UnifiedTestRunner } from '@/e2e/test-runner'
const runner = new UnifiedTestRunner()
await runner.discoverTests() // Finds all 40+ tests
```
## Learning Resources
For detailed information about JSON test format and patterns:
- `schemas/package-schemas/tests_schema.json` - Complete schema definition
- `scripts/migrate-tests/README.md` - Migration tooling documentation
- `e2e/test-runner/README.md` - Unified test runner documentation
- `/AGENTS.md` - Testing best practices and patterns
## Next Steps
1. **Learn** from this package's patterns
2. **Create** similar packages with your own test suites
3. **Migrate** existing TypeScript tests using migration tooling
4. **Validate** your tests against the schema
5. **Execute** tests with the unified test runner
This is a **living example** - refer to it when writing new declarative tests!
