### Install Mockingjay via CocoaPods (Ruby)

Source: https://github.com/kylef/mockingjay/blob/master/README.md

Instructions for adding Mockingjay as a dependency using the CocoaPods dependency manager. Add this line to your Podfile to include the library in your project.

```Ruby
pod 'Mockingjay'
```

### Stub with JSON Data from File Fixture (Swift)

Source: https://github.com/kylef/mockingjay/blob/master/README.md

Demonstrates loading JSON data from a local file fixture within a test setup method (`setUp`) and using the `jsonData` builder to create a stub response with that data.

```Swift
override func setUp() {
  super.setUp()
  let url = Bundle(for: type(of: self)).url(forResource: "fixture", withExtension: "json")!
  let data = try! Data(contentsOf: url)
  stub(matcher, jsonData(data))
}
```

--------------------------------

### Define Custom Request Matcher Function (Swift)

Source: https://github.com/kylef/mockingjay/blob/master/README.md

Provides an example of creating a custom function that determines whether a given URLRequest should be matched by a stub. The function takes a URLRequest and returns a boolean value.

```Swift
func matcher(request:URLRequest) -> Bool {
  return true  // Let's match this request
}

stub(matcher, failure(error))
```

--------------------------------

### Stub HTTP Request with URI Template and JSON (Swift)

Source: https://github.com/kylef/mockingjay/blob/master/README.md

Demonstrates creating a simple HTTP stub that matches requests based on a URI template and responds with a JSON body. The `uri` function uses the URITemplate.swift library for flexible path matching.

```Swift
let body = [ "user": "Kyle" ]
stub(uri("/{user}/{repository}"), json(body))
```

--------------------------------

### Stub Specific HTTP Method with JSON Response (Swift)

Source: https://github.com/kylef/mockingjay/blob/master/README.md

Shows how to create a stub that matches a specific HTTP method (PUT in this case) and a URI, responding with a JSON body. The `http` matcher allows specifying the required method.

```Swift
let body = [ "description": "Kyle" ]
stub(http(.put, uri: "/kylef/Mockingjay"), json(body))
```

--------------------------------

### Stub All Requests with Specific HTTP Status (Swift)

Source: https://github.com/kylef/mockingjay/blob/master/README.md

Shows how to stub all HTTP requests to return a specific HTTP status code, such as 404 Not Found. The `http` builder can also be configured with headers and a body.

```Swift
stub(everything, http(status: 404))
```

--------------------------------

### Define Custom Response Builder Function (Swift)

Source: https://github.com/kylef/mockingjay/blob/master/README.md

Shows how to create a custom function that constructs the Response object for a matched request. The function takes a URLRequest and returns a Mockingjay `Response` enum value.

```Swift
func builder(request: URLRequest) -> Response {
  let response = HTTPURLResponse(url: request.url!, statusCode: 200, httpVersion: nil, headerFields: nil)!
  return .success(response, .noContent)
}

stub(matcher, builder)
```

--------------------------------

### Stub All Requests to Fail with Error (Swift)

Source: https://github.com/kylef/mockingjay/blob/master/README.md

Illustrates how to configure Mockingjay to make all outgoing HTTP requests result in a specified error. The `everything` matcher matches any request, and `failure` builds an error response.

```Swift
let error = NSError()
stub(everything, failure(error))
```

--------------------------------

### Updating Mockingjay Response API (Swift)

Source: https://github.com/kylef/mockingjay/blob/master/CHANGELOG.md

This snippet illustrates the breaking change in Mockingjay 2.0.0 where the response content specification transitioned from using an optional `NSData` to a `Download` enum. The first code block shows the new syntax using `.NoContent` or `.Content(data)`, while the second shows the deprecated syntax.

```Swift
.Success(response, .NoContent)
.Success(response, .Content(data))
```

```Swift
.Success(response, nil)
.Success(response, data)
```

--------------------------------

### Streaming Stubbed Response Data in Mockingjay (Swift)

Source: https://github.com/kylef/mockingjay/blob/master/CHANGELOG.md

Introduced in Mockingjay 2.0.0, this enhancement allows simulating streaming response data. This snippet demonstrates how to use the `.StreamContent` case of the new `Download` enum, specifying the data and the chunk size for streaming.

```Swift
.Success(response, .StreamContent(data, inChunksOf: 1024))
```

=== COMPLETE CONTENT === This response contains all available snippets from this library. No additional content exists. Do not make further requests.
