A light-weight TDD / BDD framework for Objective-C.

Status

FEATURES

An Objective-C RSpec-like BDD DSL
Quick and easy set up
Built on top of XCTest
Excellent Xcode integration

SCREENSHOT

SETUP

Use CocoaPods, Carthage or Set up manually

CocoaPods

Add Specta to your project's Podfile:

target :MyApp do
  # your app dependencies
end

target :MyAppTests do
  pod 'Specta', '~> 0.5'
  # pod 'Expecta',     '~> 0.3'   # expecta matchers
  # pod 'OCMock',      '~> 2.2'   # OCMock
  # pod 'OCHamcrest',  '~> 3.0'   # hamcrest matchers
  # pod 'OCMockito',   '~> 1.0'   # OCMock
  # pod 'LRMocky',     '~> 0.9'   # LRMocky
end

Run pod update or pod install in your project directory.

Carthage

Add Specta to your project's Cartfile.private
```
github "specta/specta" ~> 0.5
```
Run carthage update in your project directory
Drag the appropriate Specta.framework for your platform (located in Carthage/Build/) into your application’s Xcode project, and add it to your test target(s).
If you are building for iOS, a new Run Script Phase must be added to copy the framework. The instructions can be found on Carthage's getting started instructions

SETTING UP MANUALLY

Clone from Github.
Run rake in project root to build.
Add a "Cocoa/Cocoa Touch Unit Testing Bundle" target if you don't already have one.
Copy and add all header files in Products folder to the Test target in your Xcode project.
For OS X projects, copy and add Specta.framework in Products/osx folder to the test target in your Xcode project. For iOS projects, copy and add Specta.framework in Products/ios folder to the test target in your Xcode project. You can alternatively use libSpecta.a, if you prefer to add it as a static library for your project. (iOS 7 and below require this)
Add -ObjC and -all_load to the "Other Linker Flags" build setting for the test target in your Xcode project.

EXAMPLE

#import <Specta/Specta.h> // #import "Specta.h" if you're using libSpecta.a

SharedExamplesBegin(MySharedExamples)
// Global shared examples are shared across all spec files.

sharedExamplesFor(@"foo", ^(NSDictionary *data) {
    __block id bar = nil;
    beforeEach(^{
        bar = data[@"bar"];
    });
    it(@"should not be nil", ^{
        XCTAssertNotNil(bar);
    });
});

SharedExamplesEnd

SpecBegin(Thing)

describe(@"Thing", ^{
  sharedExamplesFor(@"another shared behavior", ^(NSDictionary *data) {
    // Locally defined shared examples can override global shared examples within its scope.
  });

  beforeAll(^{
    // This is run once and only once before all of the examples
    // in this group and before any beforeEach blocks.
  });

  beforeEach(^{
    // This is run before each example.
  });

  it(@"should do stuff", ^{
    // This is an example block. Place your assertions here.
  });

  it(@"should do some stuff asynchronously", ^{
    waitUntil(^(DoneCallback done) {
      // Async example blocks need to invoke done() callback.
      done();
    });
  });

  itShouldBehaveLike(@"a shared behavior", @{@"key" : @"obj"});

  itShouldBehaveLike(@"another shared behavior", ^{
    // Use a block that returns a dictionary if you need the context to be evaluated lazily,
    // e.g. to use an object prepared in a beforeEach block.
    return @{@"key" : @"obj"};
  });

  describe(@"Nested examples", ^{
    it(@"should do even more stuff", ^{
      // ...
    });
  });

  pending(@"pending example");

  pending(@"another pending example", ^{
    // ...
  });

  afterEach(^{
    // This is run after each example.
  });

  afterAll(^{
    // This is run once and only once after all of the examples
    // in this group and after any afterEach blocks.
  });
});

SpecEnd

beforeEach and afterEach are also aliased as before and after respectively.
describe is also aliased as context.
it is also aliased as example and specify.
itShouldBehaveLike is also aliased as itBehavesLike.
Use pending or prepend x to describe, context, example, it, and specify to mark examples or groups as pending.
Use ^(DoneCallback done) as shown in the example above to make examples wait for completion. done() callback needs to be invoked to let Specta know that your test is complete. The default timeout is 10.0 seconds but this can be changed by calling the function setAsyncSpecTimeout(NSTimeInterval timeout).
(before|after)(Each/All) also accept ^(DoneCallback done)s.
Do #define SPT_CEDAR_SYNTAX before importing Specta if you prefer to write SPEC_BEGIN and SPEC_END instead of SpecBegin and SpecEnd.
Prepend f to your describe, context, example, it, and specify to set focus on examples or groups. When specs are focused, all unfocused specs are skipped.
To use original XCTest reporter, set an environment variable named SPECTA_REPORTER_CLASS to SPTXCTestReporter in your test scheme.
Set an environment variable SPECTA_NO_SHUFFLE with value 1 to disable test shuffling.
Set an environment variable SPECTA_SEED to specify the random seed for test shuffling.

Standard XCTest matchers such as XCTAssertEqualObjects and XCTAssertNil work, but you probably want to add a nicer matcher framework - Expecta to your setup. Or if you really prefer, OCHamcrest works fine too. Also, add a mocking framework: OCMock.

RUNNING TESTS IN COMMAND LINE

Run rake test in the cloned folder.
