# Nocilla [](https://travis-ci.org/luisobo/Nocilla)[](http://cocoadocs.org/docsets/Nocilla)[](http://cocoadocs.org/docsets/Nocilla)[](http://cocoadocs.org/docsets/Nocilla)
Stunning HTTP stubbing for iOS and OS X. Testing HTTP requests has never been easier.
This library was inspired by [WebMock](https://github.com/bblimke/webmock) and it's using [this approach](http://www.infinite-loop.dk/blog/2011/09/using-nsurlprotocol-for-injecting-test-data/) to stub the requests.
## Features
* Stub HTTP and HTTPS requests in your unit tests.
* Supports NSURLConnection, NSURLSession and ASIHTTPRequest.
* Awesome DSL that will improve the readability and maintainability of your tests.
* Match requests with regular expressions.
* Stub requests with errors.
* Tested.
* Fast.
* Extendable to support more HTTP libraries.
## Installation
### As a [CocoaPod](http://cocoapods.org/)
Just add this to your Podfile
```ruby
pod 'Nocilla'
```
### Other approaches
* You should be able to add Nocilla to you source tree. If you are using git, consider using a `git submodule`
## Usage
_Yes, the following code is valid Objective-C, or at least, it should be_
The following examples are described using [Kiwi](https://github.com/kiwi-bdd/Kiwi)
### Common parts
Until Nocilla can hook directly into Kiwi, you will have to include the following snippet in the specs you want to use Nocilla:
```objc
#import "Kiwi.h"
#import "Nocilla.h"
SPEC_BEGIN(ExampleSpec)
beforeAll(^{
[[LSNocilla sharedInstance] start];
});
afterAll(^{
[[LSNocilla sharedInstance] stop];
});
afterEach(^{
[[LSNocilla sharedInstance] clearStubs];
});
it(@"should do something", ^{
// Stub here!
});
SPEC_END
```
### Stubbing requests
#### Stubbing a simple request
It will return the default response, which is a 200 and an empty body.
```objc
stubRequest(@"GET", @"http://www.google.com");
```
#### Stubbing requests with regular expressions
```objc
stubRequest(@"GET", @"^http://(.*?)\\.example\\.com/v1/dogs\\.json".regex);
```
#### Stubbing a request with a particular header
```objc
stubRequest(@"GET", @"https://api.example.com").
withHeader(@"Accept", @"application/json");
```
#### Stubbing a request with multiple headers
Using the `withHeaders` method makes sense with the Objective-C literals, but it accepts an NSDictionary.
```objc
stubRequest(@"GET", @"https://api.example.com/dogs.json").
withHeaders(@{@"Accept": @"application/json", @"X-CUSTOM-HEADER": @"abcf2fbc6abgf"});
```
#### Stubbing a request with a particular body
```objc
stubRequest(@"POST", @"https://api.example.com/dogs.json").
withHeaders(@{@"Accept": @"application/json", @"X-CUSTOM-HEADER": @"abcf2fbc6abgf"}).
withBody(@"{\"name\":\"foo\"}");
```
You can also use `NSData` for the request body:
```objc
stubRequest(@"POST", @"https://api.example.com/dogs.json").
withHeaders(@{@"Accept": @"application/json", @"X-CUSTOM-HEADER": @"abcf2fbc6abgf"}).
withBody([@"foo" dataUsingEncoding:NSUTF8StringEncoding]);
```
It even works with regular expressions!
```objc
stubRequest(@"POST", @"https://api.example.com/dogs.json").
withHeaders(@{@"Accept": @"application/json", @"X-CUSTOM-HEADER": @"abcf2fbc6abgf"}).
withBody(@"^The body start with this".regex);
```
#### Returning a specific status code
```objc
stubRequest(@"GET", @"http://www.google.com").andReturn(404);
```
#### Returning a specific status code and header
The same approch here, you can use `withHeader` or `withHeaders`
```objc
stubRequest(@"POST", @"https://api.example.com/dogs.json").
andReturn(201).
withHeaders(@{@"Content-Type": @"application/json"});
```
#### Returning a specific status code, headers and body
```objc
stubRequest(@"GET", @"https://api.example.com/dogs.json").
andReturn(201).
withHeaders(@{@"Content-Type": @"application/json"}).
withBody(@"{\"ok\":true}");
```
You can also use `NSData` for the response body:
```objc
stubRequest(@"GET", @"https://api.example.com/dogs.json").
andReturn(201).
withHeaders(@{@"Content-Type": @"application/json"}).
withBody([@"bar" dataUsingEncoding:NSUTF8StringEncoding]);
```
#### Returning raw responses recorded with `curl -is`
`curl -is http://api.example.com/dogs.json > /tmp/example_curl_-is_output.txt`
```objc
stubRequest(@"GET", @"https://api.example.com/dogs.json").
andReturnRawResponse([NSData dataWithContentsOfFile:@"/tmp/example_curl_-is_output.txt"]);
```
#### All together
```objc
stubRequest(@"POST", @"https://api.example.com/dogs.json").
withHeaders(@{@"Accept": @"application/json", @"X-CUSTOM-HEADER": @"abcf2fbc6abgf"}).
withBody(@"{\"name\":\"foo\"}").
andReturn(201).
withHeaders(@{@"Content-Type": @"application/json"}).
withBody(@"{\"ok\":true}");
```
#### Making a request fail
This will call the failure handler (callback, delegate... whatever your HTTP client uses) with the specified error.
```objc
stubRequest(@"POST", @"https://api.example.com/dogs.json").
withHeaders(@{@"Accept": @"application/json", @"X-CUSTOM-HEADER": @"abcf2fbc6abgf"}).
withBody(@"{\"name\":\"foo\"}").
andFailWithError([NSError errorWithDomain:@"foo" code:123 userInfo:nil]);
```
#### Replacing a request stub
If you need to change the response of a single request, simply re-stub the request:
```objc
stubRequest(@"POST", @"https://api.example.com/authorize/").
andReturn(401);
// Some test expectation...
stubRequest(@"POST", @"https://api.example.com/authorize/").
andReturn(200);
```
### Unexpected requests
If some request is made but it wasn't stubbed, Nocilla won't let that request hit the real world. In that case your test should fail.
At this moment Nocilla will raise an exception with a meaningful message about the error and how to solve it, including a snippet of code on how to stub the unexpected request.
### Testing asynchronous requests
When testing asynchrounous requests your request will be sent on a different thread from the one on which your test is executed. It is important to keep this in mind, and design your test in such a way that is has enough time to finish. For instance ```tearDown()``` when using ```XCTest``` and ```afterEach()``` when using [Quick](https://github.com/Quick/Quick) and [Nimble](https://github.com/Quick/Nimble) will cause the request never to complete.
