+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.

+
+Installing
+----------
+
+## CocoaPods
+
+You need to be using CocoaPods 0.36 Beta 1 or higher. Your `Podfile` should look
+something like the following.
+
+```rb
+platform :ios, '8.0'
+
+source 'https://github.com/CocoaPods/Specs.git'
+
+# Whichever pods you need for your app go here.
+
+target 'YOUR_APP_NAME_HERE_Tests', :exclusive => true do
+  pod 'Nimble-Snapshots'
+  pod 'Quick' # if you want to use it with Quick
+end
+```
+
+Then run:
+```
+$ pod install
+```
+
+## Carthage
+
+You need to be using Carthage 0.18 or higher. Your `Cartfile` (or `Cartfile.private`) should look
+something like the following.
+
+```rb
+github "Quick/Quick" ~> 1.0
+github "Quick/Nimble" ~> 7.0
+github "facebook/ios-snapshot-test-case" "2.1.4"
+github "ashfurrow/Nimble-Snapshots"
+```
+
+Then run:
+```
+$ carthage bootstrap --platform iOS --toolchain com.apple.dt.toolchain.Swift_3_0
+```
+
+Use
+---
+
+Your tests will look something like the following.
+
+```swift
+import Quick
+import Nimble
+import Nimble_Snapshots
+import UIKit
+
+class MySpec: QuickSpec {
+    override func spec() {
+        describe("in some context") {
+            it("has valid snapshot") {
+                let view = ... // some view you want to test
+                expect(view).to( haveValidSnapshot() )
+            }
+        }
+    }
+}
+```
+
+There are some options for testing the validity of snapshots. Snapshots can be
+given a name:
+
+```swift
+expect(view).to( haveValidSnapshot(named: "some custom name") )
+```
+
+We also have a prettier syntax for custom-named snapshots:
+
+```swift
+expect(view) == snapshot("some custom name")
+```
+
+To record snapshots, just replace `haveValidSnapshot()` with `recordSnapshot()`
+and `haveValidSnapshot(named:)` with `recordSnapshot(named:)`. We also have a
+handy emoji operator.
+
+```swift
+📷(view)
+📷(view, "some custom name")
+```
+
+By default, this pod will put the reference images inside a `ReferenceImages`
+directory; we try to put this in a place that makes sense (inside your unit
+tests directory). If we can't figure it out, or if you want to use your own
+directory instead, call `setNimbleTestFolder()` with the name of the directory
+in your unit test's path that we should use. For example, if the tests are in
+`App/AppTesting/`, you can call it with `AppTesting`.
+
+If you have any questions or run into any trouble, feel free to open an issue
+on this repo.
+
+## Dynamic Type
+
+Testing Dynamic Type manually is boring and no one seems to remember doing it
+when implementing a view/screen, so you can have snapshot tests according to
+content size categories.
+
+In order to use Dynamic Type testing, make sure to provide a valid `Host Application` in your testing target.
+
+Then you can use the `haveValidDynamicTypeSnapshot` and
+`recordDynamicTypeSnapshot` matchers:
+
+```swift
+// expect(view).to(recordDynamicTypeSnapshot()
+expect(view).to(haveValidDynamicTypeSnapshot())
+
+// You can also just test some sizes:
+expect(view).to(haveValidDynamicTypeSnapshot(sizes: [UIContentSizeCategoryExtraLarge]))
+
+// If you prefer the == syntax, we got you covered too:
+expect(view) == dynamicTypeSnapshot()
+expect(view) == dynamicTypeSnapshot(sizes: [UIContentSizeCategoryExtraLarge])
+```
+
+Note that this will post an `UIContentSizeCategoryDidChangeNotification`,
+so your views/view controllers need to observe that and update themselves.
+
+For more info on usage, check out the
+[dynamic type tests](Bootstrap/BootstrapTests/DynamicTypeTests.swift).
+
+
+
+## Dynamic Size
+
+Testing the same view with many sizes is easy but error prone. It easy to fix one test
+on change and forget the others. For this we create a easy way to tests all sizes at same time.
+
+You can use the new `haveValidDynamicSizeSnapshot` and `recordDynamicSizeSnapshot`
+matchers to test multiple sizes at once:
+
+```swift
+let sizes = ["SmallSize": CGSize(width: 44, height: 44),
+"MediumSize": CGSize(width: 88, height: 88),
+"LargeSize": CGSize(width: 132, height: 132)]
+
+// expect(view).to(recordDynamicSizeSnapshot(sizes: sizes))
+expect(view).to(haveValidDynamicSizeSnapshot(sizes: sizes))
+
+// You can also just test some sizes:
+expect(view).to(haveValidDynamicSizeSnapshot(sizes: sizes))
+
+// If you prefer the == syntax, we got you covered too:
+expect(view) == dynamicSizeSnapshot(sizes: sizes)
+expect(view) == dynamicSizeSnapshot(sizes: sizes)
+```
+
+By default, the size will be set on the view using the frame property. To change this behavior
+you can use the `ResizeMode` enum:
+
+```swift
+public enum ResizeMode {
+  case frame
+  case constrains
+  case block(resizeBlock: (UIView, CGSize) -> Void)
+  case custom(viewResizer: ViewResizer)
+}
+```
+To use the enum you can `expect(view) == dynamicSizeSnapshot(sizes: sizes, resizeMode: newResizeMode)`.
+For custom behavior you can use `ResizeMode.block`. The block will be call on every resize. Or you can
+implement the `ViewResizer` protocol and resize yourself.
+The custom behavior can be used to record the views too.
+
+For more info on usage, check the [dynamic sizes tests](Bootstrap/BootstrapTests/DynamicSizeTests.swift).

+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
