Mock objects framework

I released new version of mock objects framework named Mocketry. It is renamed, cleanup and improved BehaviorMockup framework.

Short review:

Mocketry is smalltalk mock object framework based on specifications.

It support all kind specifications for object interactions:

• arguments constraint
• context specs
• actions
• usage specs
• ordering messages.

Behavior specs build by pure message sends to mock objects and has full refactoring support.

Mock objects implements some special proxy mechanizm for support development tools (debugging).

Mocketry implements "scenario system" that allows transparent access to mock objects. If you need mock object just get it in scenario block argument:

[:mockA :mockB |
	"some set up code"

	[mockA someMessageWith: 20.
	mockB someMessage2] 
		should strictly satisfy:  

	[mockA someMessageWith: (Kind of: Integer).
	mockB someMessage2 willReturn: #someValue].

	"maybe some assertions: 
		var should be: true. 
		... "
] runScenario

First block here is tested behavior. Second - expected message sends.

Or you can create MockObject instance variable in setUp method: "some := MockObject new". And you get mock object named 'some' in your "scenario tests".

Mocketry provide special SSpec-like extended DSL based on pragmas for all kind of specifications (state and behavior).

10 should be an instance of: SmallInteger
[ZeroDivide raiseSignal] should raise: ZeroDivide.

...
[mockA someMessage] should lenient satisfy: [mockA someMessage]
...

This looks really nice! Can you give some pointers on where to read a bit
more about the various kinds of specs provided (state, context, usage, ...),
and how the <pragmas> are used? (I will browse the code too :-)

Any pre-requisites? Use standard test runner?

Thanks - Sophie

2008/2/18, itsme213 <[hidden email]>:Only pre-requisite is SMock package for Mocketry tests. Maybe Mocketry should have two different packages: for tests and for base code. Then base code doesn't need any pre-requisites.

About test runner:

With Mocketry use can use any Testing framework and TestRunner that you want.
You doesn't need create special Base TestCase class that provide mock objects facilities.
If you need mock object just get it from scenario block argument or testcase inst var (empty or initialized in setUp method (for example) by "instVar := MockObject new").
In test methods you don't worry about what is mock objects, you just write specification of objects interaction and test it.
Scenario system transparently creates and controls mock objects by method context.
