dartmocks 0.3.1

A mock framework inspired by RSpec-Mocks.

DartMocks

DartMocks is a mock framework for Dart inspired by RSpec. It's built on top of unittest/mock.

Installation

Add the DartMocks dependency to your project’s pubspec.yaml.

name: my_project
dependencies:
  dartmocks: any

And run pub install.

Examples

Stubs

var testStub = stub('My Stub');
testStub.stub('method').args(1, true).andReturn(10);
expect(testStub.method(1, true), equals(10));

Or

var testStub = stub("My Stub", {"method" : 10});
expect(testStub.method(), equals(10));

Expectations

var testDouble = mock('Double');
testDouble.shouldReceive('method').args('arg');

testDouble.method('arg');

expect(testDouble.verify, returnsNormally);

OR

var testDouble = mock('Double');
testDouble.shouldReceive('method');

expect(testDouble.verify, throws);

Test doubles implementing interfaces

abstract class Greeter {
  String greet();
}
String greet(Greeter m) => m.greet();
class GreeterDouble extends TestDouble implements Greeter {}

And the test:

var s = new GreeterDouble()
        ..name = "Greeter"
        ..stub("greet").andReturn("Result");

expect(greet(s), equals("Result"));;
