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.png)](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
```
### 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).

A matcher framework for Objective-C and Cocoa.
## Introduction
## 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.

Expecta is framework-agnostic: it works well with XCTest and XCTest-compatible test frameworks such as [Specta](http://github.com/petejkim/specta/).
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/).
## Installation
You can setup Expecta using [Carthage](https://github.com/Carthage/Carthage), [CocoaPods](http://github.com/CocoaPods/CocoaPods) or [completely manually](#setting-up-manually).
### 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).
### CocoaPods
1. Add Expecta to your project's `Podfile`:
```ruby
target :MyApp do
# Your app's dependencies
end
target :MyAppTests do
pod 'Expecta', '~> 1.0.0'
end
```
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
```

> `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
### 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
### Asynchronous Testing
Every matcher can be made to perform asynchronous testing by prepending `.will`, `.willNot` or `after(...)`:
@ -172,14 +114,14 @@ describe(@"Foo", ^{
});
```
## Forced Failing
### 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 NEW MATCHERS
Writing a new matcher is easy with special macros provided by Expecta. Take a look at how `.beKindOf()` matcher is defined:
@ -246,7 +188,7 @@ EXPMatcherImplementationBegin(beKindOf, (Class expected)) {
EXPMatcherImplementationEnd
```
## Dynamic Predicate Matchers
## 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.
@ -282,6 +224,68 @@ You can now write your assertion as follows:
expect(lightSwitch).isTurnedOn();

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.
