+Expecta Matchers for FBSnapshotTestCase
+=======================================
+
+[Expecta](https://github.com/specta/expecta) matchers for [ios-snapshot-test-case](https://github.com/facebook/ios-snapshot-test-case).
+
+[![Build Status](https://travis-ci.org/dblock/ios-snapshot-test-case-expecta.svg)](https://travis-ci.org/dblock/ios-snapshot-test-case-expecta)
+
+### Usage
+
+Add `Expecta+Snapshots` to your Podfile, the latest `FBSnapshotTestCase` will come in as a dependency.
+
+``` ruby
+pod 'Expecta+Snapshots'
+```
+
+### App setup
+
+Use `expect(view).to.recordSnapshotNamed(@"unique snapshot name")` to record a snapshot and `expect(view).to.haveValidSnapshotNamed(@"unique snapshot name")` to check it.
+
+If you project was compiled with Specta included, you have two extra methods that use the spec hierarchy to generate the snapshot name for you: `recordSnapshot()` and `haveValidSnapshot()`. You should only call these once per `it()` block.
+
+If you need the `usesDrawViewHierarchyInRect` property in order to correctly render UIVisualEffect, UIAppearance and Size Classes, call `[Expecta setUsesDrawViewHierarchyInRect:NO];` inside `beforeAll`.
+
+``` Objective-C
+#define EXP_SHORTHAND
+#include <Specta/Specta.h>
+#include <Expecta/Expecta.h>
+#include <Expecta+Snapshots/EXPMatchers+FBSnapshotTest.h>
+#include "FBExampleView.h"
+
+SpecBegin(FBExampleView)
+
+describe(@"manual matching", ^{
+
+    it(@"matches view", ^{
+        FBExampleView *view = [[FBExampleView alloc] initWithFrame:CGRectMake(0, 0, 64, 64)];
+        expect(view).to.recordSnapshotNamed(@"FBExampleView");
+        expect(view).to.haveValidSnapshotNamed(@"FBExampleView");
+    });
+
+    it(@"doesn't match a view", ^{
+        FBExampleView *view = [[FBExampleView alloc] initWithFrame:CGRectMake(0, 0, 64, 64)];
+        expect(view).toNot.haveValidSnapshotNamed(@"FBExampleViewDoesNotExist");
+    });
+
+});
+
+describe(@"test name derived matching", ^{
+
+    it(@"matches view", ^{
+        FBExampleView *view = [[FBExampleView alloc] initWithFrame:CGRectMake(0, 0, 64, 64)];
+        expect(view).to.recordSnapshot();
+        expect(view).to.haveValidSnapshot();
+    });
+
+    it(@"doesn't match a view", ^{
+        FBExampleView *view = [[FBExampleView alloc] initWithFrame:CGRectMake(0, 0, 64, 64)];
+        expect(view).toNot.haveValidSnapshot();
+    });
+
+});
+
+SpecEnd
+```

+If for some reason you want to specify a tolerance for your test, you can use either named or unnamed matchers, where the `tolerance` parameter is a `CGFloat` in the interval `[0, 1]` and it represents the minimum ratio of unmatched points by the total number of points in your snapshot. In the example below, a tolerance of `0.01` means our `view` could be up to `1%` different from the reference image.
+
+``` Objective-C
+expect(view).to.haveValidSnapshotWithTolerance(0.01);
+expect(view).to.haveValidSnapshotNamedWithTolerance(@"unique snapshot name", 0.01);
+```
+
+### Sane defaults
+
+`EXPMatchers+FBSnapshotTest` will automatically figure out the tests folder, and [add a reference image](https://github.com/dblock/ios-snapshot-test-case-expecta/blob/master/EXPMatchers%2BFBSnapshotTest.m#L84-L85) directory, if you'd like to override this, you should include a `beforeAll` block setting the `setGlobalReferenceImageDir` in each file containing tests.
+
+```
+beforeAll(^{
+    setGlobalReferenceImageDir(FB_REFERENCE_IMAGE_DIR);
+});
+```
+
+
+### Example
+
+A complete project can be found in [FBSnapshotTestCaseDemo](FBSnapshotTestCaseDemo).
+
+Notably, take a look at [FBSnapshotTestCaseDemoSpecs.m](FBSnapshotTestCaseDemo/FBSnapshotTestCaseDemoTests/FBSnapshotTestCaseDemoSpecs.m) for a complete example, which is an expanded Specta version version of [FBSnapshotTestCaseDemoTests.m](https://github.com/facebook/ios-snapshot-test-case/blob/master/FBSnapshotTestCaseDemo/FBSnapshotTestCaseDemoTests/FBSnapshotTestCaseDemoTests.m).
+
+Finally you can consult the tests for [ARTiledImageView](https://github.com/dblock/ARTiledImageView/tree/master/IntegrationTests) or [NAMapKit](https://github.com/neilang/NAMapKit/tree/master/Demo/DemoTests).

+# Expecta [![Build Status](http://img.shields.io/travis/specta/expecta/master.svg?style=flat)](https://travis-ci.org/specta/expecta) [![Pod Version](http://img.shields.io/cocoapods/v/Expecta.svg?style=flat)](http://cocoadocs.org/docsets/Expecta/)
+
+A matcher framework for Objective-C and Cocoa.
+
+## FEATURES
+
+The main advantage of using Expecta over other matcher frameworks is that you do not have to specify the data types. Also, the syntax of Expecta matchers is much more readable and does not suffer from parenthesitis.
+
+```objective-c
+expect(@"foo").to.equal(@"foo"); // `to` is a syntactic sugar and can be safely omitted.
+expect(foo).notTo.equal(1);
+expect([bar isBar]).to.equal(YES);
+expect(baz).to.equal(3.14159);
+```
+
+Expecta is framework-agnostic: it works well with XCTest and XCTest-compatible test frameworks such as [Specta](http://github.com/petejkim/specta/), or [Kiwi](https://github.com/kiwi-bdd/Kiwi/).
+
+
+## MATCHERS
+
+> `expect(x).to.equal(y);` compares objects or primitives x and y and passes if they are identical (==) or equivalent isEqual:).
+
+> `expect(x).to.beIdenticalTo(y);` compares objects x and y and passes if they are identical and have the same memory address.
+
+> `expect(x).to.beNil();` passes if x is nil.
+
+> `expect(x).to.beTruthy();` passes if x evaluates to true (non-zero).
+
+> `expect(x).to.beFalsy();` passes if x evaluates to false (zero).
+
+> `expect(x).to.contain(y);` passes if an instance of NSArray or NSString x contains y.
+
+> `expect(x).to.beSupersetOf(y);` passes if an instance of NSArray, NSSet, NSDictionary or NSOrderedSet x contains all elements of y.
+
+> `expect(x).to.haveCountOf(y);` passes if an instance of NSArray, NSSet, NSDictionary or NSString x has a count or length of y.
+
+> `expect(x).to.beEmpty();` passes if an instance of NSArray, NSSet, NSDictionary or NSString x has a count or length of .
+
+> `expect(x).to.beInstanceOf([Foo class]);` passes if x is an instance of a class Foo.
+
+> `expect(x).to.beKindOf([Foo class]);` passes if x is an instance of a class Foo or if x is an instance of any class that inherits from the class Foo.
+
+> `expect([Foo class]).to.beSubclassOf([Bar class]);` passes if the class Foo is a subclass of the class Bar or if it is identical to the class Bar. Use beKindOf() for class clusters.
+
+> `expect(x).to.beLessThan(y);` passes if `x` is less than `y`.
+
+> `expect(x).to.beLessThanOrEqualTo(y);` passes if `x` is less than or equal to `y`.
+
+> `expect(x).to.beGreaterThan(y);` passes if `x` is greater than `y`.
+
+> `expect(x).to.beGreaterThanOrEqualTo(y);` passes if `x` is greater than or equal to `y`.
+
+> `expect(x).to.beInTheRangeOf(y,z);` passes if `x` is in the range of `y` and `z`.
+
+> `expect(x).to.beCloseTo(y);` passes if `x` is close to `y`.
+
+> `expect(x).to.beCloseToWithin(y, z);` passes if `x` is close to `y` within `z`.
+
+> `expect(^{ /* code */ }).to.raise(@"ExceptionName");` passes if a given block of code raises an exception named `ExceptionName`.
+
+> `expect(^{ /* code */ }).to.raiseAny();` passes if a given block of code raises any exception.
+
+> `expect(x).to.conformTo(y);` passes if `x` conforms to the protocol `y`.
+
+> `expect(x).to.respondTo(y);` passes if `x` responds to the selector `y`.
+
+> `expect(^{ /* code */ }).to.notify(@"NotificationName");` passes if a given block of code generates an NSNotification amed `NotificationName`.
+
+> `expect(^{ /* code */ }).to.notify(notification);` passes if a given block of code generates an NSNotification equal to the passed `notification`.
+
+> `expect(x).to.beginWith(y);` passes if an instance of NSString, NSArray, or NSOrderedSet `x` begins with `y`. Also liased by `startWith`
+
+> `expect(x).to.endWith(y);` passes if an instance of NSString, NSArray, or NSOrderedSet `x` ends with `y`.

+> `expect(x).to.match(y);` passes if an instance of NSString `x` matches regular expression (given as NSString) `y` one or more times.
+
+### Inverting Matchers
+
+Every matcher's criteria can be inverted by prepending `.notTo` or `.toNot`:
+
+>`expect(x).notTo.equal(y);` compares objects or primitives x and y and passes if they are *not* equivalent.
+
+### Asynchronous Testing
+
+Every matcher can be made to perform asynchronous testing by prepending `.will`, `.willNot` or `after(...)`:
+
+>`expect(x).will.beNil();` passes if x becomes nil before the default timeout.
+>
+>`expect(x).willNot.beNil();` passes if x becomes non-nil before the default timeout.
+>
+>`expect(x).after(3).to.beNil();` passes if x becoms nil after 3.0 seconds.
+>
+>`expect(x).after(2.5).notTo.equal(42);` passes if x doesn't equal 42 after 2.5 seconds.
+
+The default timeout is 1.0 second and is used for all matchers if not otherwise specified. This setting can be changed by calling `[Expecta setAsynchronousTestTimeout:x]`, where `x` is the desired timeout in seconds.
+
+```objective-c
+describe(@"Foo", ^{
+  beforeAll(^{
+    // All asynchronous matching using `will` and `willNot`
+    // will have a timeout of 2.0 seconds
+    [Expecta setAsynchronousTestTimeout:2];
+  });
+
+  it(@"will not be nil", ^{
+    // Test case where default timeout is used
+    expect(foo).willNot.beNil();
+  });
+
+  it(@"should equal 42 after 3 seconds", ^{
+    // Signle case where timeout differs from the default
+    expect(foo).after(3).to.equal(42);
+  });
+});
+```
+
+### Forced Failing
+
+You can fail a test by using the `failure` attribute. This can be used to test branching.
+
+> `failure(@"This should not happen");` outright fails a test.
+
+
+### WRITING NEW MATCHERS
+
+Writing a new matcher is easy with special macros provided by Expecta. Take a look at how `.beKindOf()` matcher is defined:
+
+`EXPMatchers+beKindOf.h`
+
+```objective-c
+#import "Expecta.h"
+
+EXPMatcherInterface(beKindOf, (Class expected));
+// 1st argument is the name of the matcher function
+// 2nd argument is the list of arguments that may be passed in the function
+// call.
+// Multiple arguments are fine. (e.g. (int foo, float bar))
+
+#define beAKindOf beKindOf
+```
+
+`EXPMatchers+beKindOf.m`
+
+```objective-c
+#import "EXPMatchers+beKindOf.h"
+
+EXPMatcherImplementationBegin(beKindOf, (Class expected)) {
+  BOOL actualIsNil = (actual == nil);
+  BOOL expectedIsNil = (expected == nil);
+
+  prerequisite(^BOOL {
+    return !(actualIsNil || expectedIsNil);
+    // Return `NO` if matcher should fail whether or not the result is inverted
+    // using `.Not`.
+  });
+
+  match(^BOOL {
+    return [actual isKindOfClass:expected];
+    // Return `YES` if the matcher should pass, `NO` if it should not.
+    // The actual value/object is passed as `actual`.
+    // Please note that primitive values will be wrapped in NSNumber/NSValue.
+  });
+
+  failureMessageForTo(^NSString * {
+    if (actualIsNil)
+      return @"the actual value is nil/null";
+    if (expectedIsNil)
+      return @"the expected value is nil/null";
+    return [NSString
+        stringWithFormat:@"expected: a kind of %@, "
+                          "got: an instance of %@, which is not a kind of %@",
+                         [expected class], [actual class], [expected class]];
+    // Return the message to be displayed when the match function returns `YES`.
+  });
+
+  failureMessageForNotTo(^NSString * {
+    if (actualIsNil)
+      return @"the actual value is nil/null";
+    if (expectedIsNil)
+      return @"the expected value is nil/null";
+    return [NSString
+        stringWithFormat:@"expected: not a kind of %@, "
+                          "got: an instance of %@, which is a kind of %@",
+                         [expected class], [actual class], [expected class]];
+    // Return the message to be displayed when the match function returns `NO`.
+  });
+}
+EXPMatcherImplementationEnd
+```
+
+## DYNAMIC PREDICATE MATCHERS
+
+It is possible to add predicate matchers by simply defining the matcher interface, with the matcher implementation being handled at runtime by delegating to the predicate method on your object.
+
+For instance, if you have the following class:
+
+```objc
+@interface LightSwitch : NSObject
+@property (nonatomic, assign, getter=isTurnedOn) BOOL turnedOn;
+@end
+
+@implementation LightSwitch
+@synthesize turnedOn;
+@end
+```
+
+The normal way to write an assertion that the switch is turned on would be:
+
+```objc
+expect([lightSwitch isTurnedOn]).to.beTruthy();
+```
+
+However, if we define a custom predicate matcher:
+
+```objc
+EXPMatcherInterface(isTurnedOn, (void));
+```
+
+(Note: we haven't defined the matcher implementation, just it's interface)
+
+You can now write your assertion as follows:
+
+```objc
+expect(lightSwitch).isTurnedOn();
+```
+
+## INSTALLATION
+
+You can setup Expecta using [CocoaPods](http://github.com/CocoaPods/CocoaPods), [Carthage](https://github.com/Carthage/Carthage) or [completely manually](#setting-up-manually).
+
+### CocoaPods
+
+1. Add Expecta to your project's `Podfile`:
+
+```ruby
+target :MyApp do
+# your app dependencies
+
+  target :MyAppTests do
+    inherit! search_paths
+
+    pod 'Expecta', '~> 1.0'
+  end
+end
+```
+
+### Carthage
+
+1. Add Expecta to your project's `Cartfile.private`:
+
+	```ruby
+	github "specta/expecta" "master"
+	```
+
+2. Run `carthage update` in your project directory.
+3. Drag the appropriate **Expecta.framework** for your platform (located in `Carthage/Build/`) into your application’s Xcode project, and add it to your test target(s).
+
+
+2. Run `pod update` or `pod install` in your project directory.
+
+### Setting Up Manually
+
+1. Clone Expecta from Github.
+2. Run `rake` in your project directory to build the frameworks and libraries.
+3. Add a Cocoa or Cocoa Touch Unit Testing Bundle target to your Xcode project if you don't already have one.
+4. For **OS X projects**, copy and add `Expecta.framework` in the `Products/osx` folder to your project's test target.
+
+   For **iOS projects**, copy and add `Expecta.framework` in the `Products/ios` folder to your project's test target.
+
+   You can also use `libExpecta.a` if you prefer to link Expecta as a static library — iOS 7.x and below require this.
+
+6. Add `-ObjC` and `-all_load` to the **Other Linker Flags** build setting for the test target in your Xcode project.
+7. You can now use Expecta in your test classes by adding the following import:
+
+	```objective-c
+	@import Expecta; // If you're using Expecta.framework
+
+	// OR
+
+	#import <Expecta/Expecta.h> // If you're using the static library, or the framework
+	```
+
+## STATUS
+
+Expecta, and Specta are considered done projects, there are no plans for _active_ development on the project at the moment aside from ensuring future Xcode compatability.
+Therefore it is a stable dependency, but will not be moving into the Swift world. If you are looking for that, we recommend you consider [Quick](https://github.com/quick/quick) and [Nimble](https://github.com/quick/nimble).

+FBSnapshotTestCase
+======================
+
+[![Build Status](https://travis-ci.org/facebook/ios-snapshot-test-case.svg)](https://travis-ci.org/facebook/ios-snapshot-test-case) [![Cocoa Pod Version](https://cocoapod-badges.herokuapp.com/v/FBSnapshotTestCase/badge.svg)](http://cocoadocs.org/docsets/FBSnapshotTestCase/)
+
+What it does
+------------
+
+A "snapshot test case" takes a configured `UIView` or `CALayer` and uses the
+`renderInContext:` method to get an image snapshot of its contents. It
+compares this snapshot to a "reference image" stored in your source code
+repository and fails the test if the two images don't match.
+
+Why?
+----
+
+At Facebook we write a lot of UI code. As you might imagine, each type of
+feed story is rendered using a subclass of `UIView`. There are a lot of edge
+cases that we want to handle correctly:
+
+- What if there is more text than can fit in the space available?
+- What if an image doesn't match the size of an image view?
+- What should the highlighted state look like?
+
+It's straightforward to test logic code, but less obvious how you should test
+views. You can do a lot of rectangle asserts, but these are hard to understand
+or visualize. Looking at an image diff shows you exactly what changed and how
+it will look to users.
+
+We developed `FBSnapshotTestCase` to make snapshot tests easy.
+
+Installation with CocoaPods
+---------------------------
+
+1. Add the following lines to your Podfile:
+
+     ```
+     target "Tests" do
+       pod 'FBSnapshotTestCase'
+     end
+     ```
+
+   If you support iOS 7 use `FBSnapshotTestCase/Core` instead, which doesn't contain Swift support.
+
+   Replace "Tests" with the name of your test project.
+
+2. There are [three ways](https://github.com/facebook/ios-snapshot-test-case/blob/master/FBSnapshotTestCase/FBSnapshotTestCase.h#L19-L29) of setting reference image directories, the recommended one is to define `FB_REFERENCE_IMAGE_DIR` in your scheme. This should point to the directory where you want reference images to be stored. At Facebook, we normally use this:
+
+|Name|Value|
+|:---|:----|
+|`FB_REFERENCE_IMAGE_DIR`|`$(SOURCE_ROOT)/$(PROJECT_NAME)Tests/ReferenceImages`|
+
+
+![](FBSnapshotTestCaseDemo/Scheme_FB_REFERENCE_IMAGE_DIR.png)
+
+Creating a snapshot test
+------------------------
+
+1. Subclass `FBSnapshotTestCase` instead of `XCTestCase`.
+2. From within your test, use `FBSnapshotVerifyView`.
+3. Run the test once with `self.recordMode = YES;` in the test's `-setUp`
+   method. (This creates the reference images on disk.)
+4. Remove the line enabling record mode and run the test.
+
+Features
+--------
+
+- Automatically names reference images on disk according to test class and
+  selector.
+- Prints a descriptive error message to the console on failure. (Bonus:
+  failure message includes a one-line command to see an image diff if
+  you have [Kaleidoscope](http://www.kaleidoscopeapp.com) installed.)
+- Supply an optional "identifier" if you want to perform multiple snapshots
+  in a single test method.
+- Support for `CALayer` via `FBSnapshotVerifyLayer`.
+- `usesDrawViewHierarchyInRect` to handle cases like `UIVisualEffect`, `UIAppearance` and Size Classes.
+- `isDeviceAgnostic` to allow appending the device model (`iPhone`, `iPad`, `iPod Touch`, etc), OS version and screen size to the images (allowing to have multiple tests for the same «snapshot» for different `OS`s and devices).
+
+Notes
+-----
+
+Your unit test must be an "application test", not a "logic test." (That is, it
+must be run within the Simulator so that it has access to UIKit.) In Xcode 5
+and later new projects only offer application tests, but older projects will
+have separate targets for the two types.
