# iOS RxSwift Unit Test Generator

Automatically generate comprehensive unit tests for iOS RxSwift project following Clean Architecture patterns.

## When to Activate

- "generate unit tests for [file]"
- "write tests for [ViewModel/UseCase/Service]"
- "create unit tests for this file"
- "add tests for [class name]"
- "test [file path]"

## Process

### 1. Identify Target File

**Ask user for file to test** (if not provided):
```
Which file would you like to generate tests for?
Provide the file path or class name (e.g., BalanceInformationViewModel.swift)
```

**Read target file** and determine type:
- ViewModel: Has `ViewModelType`, `Input`, `Output`, `transform` method
- UseCase: Implements `*UseCaseType` protocol
- Service: Implements service protocol

### 2. Read Testing Guide

**CRITICAL**: Read the comprehensive testing guide:
```
~/Library/Application Support/Code/User/prompts/ios-mc-generate-unit-test.prompt.md
```

This guide contains ALL rules, patterns, and examples to follow.

### 3. Analyze Target File

**Extract from target file:**
- Class name and type (ViewModel/UseCase/Service)
- All dependencies (injected in initializer)
- Protocol types for each dependency
- Public methods and their signatures
- Input/Output structure (for ViewModels)
- Observable/Single/Completable return types

**Search for protocol definitions** if needed:
```bash
Glob: **/*UseCaseType.swift
Grep: "protocol [DependencyName]"
```

### 4. Generate Test File

**Create complete test file** at:
```
PayooMerchantTests/[appropriate-folder]/[ClassName]Tests.swift
```

**Folder structure:**
- ViewModels → `PayooMerchantTests/ViewModel/`
- UseCases → `PayooMerchantTests/UseCase/`
- Services → `PayooMerchantTests/Mock/Service/`

**Test file MUST include:**

1. **Required imports**:
   ```swift
   import XCTest
   import RxSwift
   import RxCocoa
   import RxTest
   import RxBlocking
   import Domain
   @testable import PayooMerchant
   ```

2. **Test class with nested mocks**:
   - ALL moc
