![MirrorDiffKit](https://raw.githubusercontent.com/Kuniwak/MirrorDiffKit/master/Documentation/Images/logo.png)

=============

A tool for providing the 2 features for efficient testing:

- Output diff between 2 any types

- Default implementation of Equatable for any types

![](./Documentation/Images/XcodePreview.png)

Usage

-----

### `diff(between: T, and: T)`

```swift

import MirrorDiffKit

// Input 2 structs or classes implements Equatable:

let a = Example(

    key1: "I'm not changed",

    key2: "I'm deleted"

)

let b = Example(

    key1: "I'm not changed",

    key2: "I'm inserted"

)

XCTAssertEqual(a, b, diff(between: a, and: b))

// XCTAssertEqual failed: ("Example(key1: "I\'m not changed", key2: "I\'m deleted")") is not equal to ("Example(key1: "I\'m not changed", key2: "I\'m inserted")") - 

//     struct Example {

//         key1: "I'm not changed"

//       - key2: "I'm deleted"

//       + key2: "I'm inserted"

//     }

```

### `Any =~ Any` and `Any !~ Any`

```swift

import MirrorDiffKit

a = NotEquatable(

    key1: "I'm not changed",

    key2: "I'm deleted"

)

b = NotEquatable(

    key1: "I'm not changed",

    key2: "I'm inserted"

)

XCTAssert(a =~ b, diff(between: a, and: b))

// XCTAssertTrue failed - 

//     struct NotEquatable {

//         key1: "I'm not changed"

//       - key2: "I'm deleted"

//       + key2: "I'm inserted"

//     }

```
