`MockUserDefaults` is a simple replacement for `NSUserDefaults`/`UserDefaults` to make test easier.

## Installation

### SwiftPM (recommended)

```swift:Package.swift

.package(url: "https://github.com/417-72KI/MockUserDefaults.git", from: "2.4.0"),

```

### CocoaPods

```ruby:Podfile

pod 'MockUserDefaults'

```

## Usage

### Objective-C

```objc

NSUserDefaults *userDefaults = [NSUserDefaults mockedUserDefaults];

[userDefaults setObject:@"string" forKey:@"key"];

XCTAssertEqualObjects([userDefaults objectForKey:@"key"], @"string");

```

### Swift

```swift

let userDefaults: UserDefaults = .mock

userDefaults.set("string", forKey: "key")

XCTAssertEqual(userDefaults.string(forKey: "key"), "string")

```

## Demo
