Specta

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

FEATURES

• RSpec-like BDD DSL
• Super quick and easy to set up
• Runs on top of OCUnit
• Excellent Xcode integration

SCREENSHOT

SETUP

Use CocoaPods

dependency 'Specta',      '~> 0.1.8'
# dependency 'Expecta',     '~> 0.2.1'   # expecta matchers
# dependency 'OCHamcrest',  '~> 1.7'     # hamcrest matchers
# dependency 'OCMock',      '~> 2.0.1'   # OCMock
# dependency 'LRMocky',     '~> 0.9.1'   # LRMocky

or

1. Clone from Github.
2. Run rake in project root to build.
3. Add a "Cocoa/Cocoa Touch Unit Testing Bundle" target if you don't already have one.
4. Copy and add all header files in products folder to the Test target in your Xcode project.
5. For OS X projects, copy and add libSpecta-macosx.a in products folder to the Test target in your Xcode project.
   For iOS projects, copy and add libSpecta-ios-universal.a in products folder to the Test target in your Xcode project.
6. Add the following to your test code.

#import "Specta.h"

Standard OCUnit matchers such as STAssertEqualObjects and STAssertNil 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.

WRITING SPECS

#import "Specta.h"

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

sharedExamplesFor(@"a shared behavior", ^(NSDictionary *data) {
  it(@"should do some stuff", ^{
    // ...
  });
});

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", ^AsyncBlock {
    // Async example blocks need to invoke done() callback.
    done();
  });

  itShouldBehaveLike(@"a shared behavior", [NSDictionary dictionaryWithObjectsAndKeys:@"obj", @"key", nil]);

  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 [NSDictionary dictionaryWithObjectsAndKeys:@"obj", @"key", nil];
  });

  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 ^AsyncBlock 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.
• (before|after)(Each/All) also accept ^AsyncBlocks.
• Do #define SPT_CEDAR_SYNTAX if you prefer to write SPEC_BEGIN and SPEC_END instead of SpecBegin and SpecEnd.
