You may use getApplicationCacheOrigins(PassRefPtr<ArrayCallback>) instead of WK APIs.

I prefer to follow the WebKit coding style except in the public header files.

Inline function would be better.

unneeded include. Already included in EWK2UnitTestBase.h.

ditto.

This comparison seems to be meaningless.

You need to add the new header to the installed headers below in the same file.

> +        originList = eina_list_append(originList, origin.release().leakRef());

calling .release() here will reset the pointer the NULL in the wrapperCache. This is probably not what you want.
Probably it should be something like eina_list_append(originList, ewk_object_ref(origin.get()))

> Source/WebKit2/UIProcess/API/efl/ewk_application_cache_manager.cpp:83
> +    Eina_List* originList = webApplicationCacheContext->manager->createOriginList(origins);

This list is never freed (leak). You should unref the list items and free the list at this end of this function.

> Source/WebKit2/UIProcess/API/efl/ewk_application_cache_manager.cpp:93
> +    Ewk_Application_Cache_Origins_Async_Get_Context* context = new Ewk_Application_Cache_Origins_Async_Get_Context(ewkApplicationCacheManager, callback, userData);

context is never freed?

> + *                        the Eina_List and its items should be freed after use. Use ewk_security_origin_unref()

No, we usually don't pass ownership of callback arguments to the client. The client should clone the list (and ref its items) if it wishes to keep them outside the callback.
This is less leak prone and common practice I believe.

?

So? This file is using Ewk types so it should include EWebKit2.h. Relying on other headers includes is bad practice.

>> Source/WebKit2/UIProcess/API/efl/tests/test_ewk2_application_cache_manager.cpp:33

So? This file is using ecore function so it should include Ecore.h. Relying on other headers includes is bad practice.

> +static void getApplicationCacheOriginsCallback(Eina_List* origins, Ewk_Error* error, void* userData)

Note that you're not freeing the origins list here, which proves my point that the current API is leak prone.

> Source/WebKit2/UIProcess/API/efl/tests/test_ewk2_application_cache_manager.cpp:111
> +    Eina_Strbuf* body = eina_strbuf_new();

Should be inside the if case otherwise it leaks if the if condition is false.

> +    }

There should probably be an else case here which sets status to SOUP_STATUS_NOT_FOUND.

> Source/WebKit2/UIProcess/API/efl/tests/test_ewk2_application_cache_manager.cpp:157
> +    const char* applicationCacheTestUrl = httpServer->getURLForPath("/application_cache.html").data();

You keep a pointer to memory owned by a temporary object (CString), this is bad and may crash.

Get rid of this useless variable and update next line to read:
ewk_view_url_set(view, httpServer->getURLForPath("/application_cache.html").data());

> Source/WebKit2/UIProcess/API/efl/tests/test_ewk2_application_cache_manager.cpp:158

There is loadUrlSync() to do this in 1 line instead of 2.

It is not meaningless, it makes sure we return the same pointer every time. This is consistent with our other tests.

I refactored EWK2UnitTestBase.h to include the EWK2UnitTestEnvironment.h, Ecore.h, Eina.h headers in http://trac.webkit.org/changeset/135349, as they are used commonly in API test cases.
Actually, I started this work as I have been pointed out that why <gtest/gtest.h> should be included in the test files even though it is already included in EWK2UnitTestBase.h file. Then according to Laszlo's comments, I moved out the duplicated headers in to EWK2UnitTestBase.h.

I agree with Christophe in general that relying on other header includes is bad practice, but when it is justified it might make sense to break the general rule. As an example most WebKit files rely on Platform.h to include Compiler.h - as we made an exception with config.h (and even added this exception to the style checker). 

The idea of EWK2UnitTestBase.h is similar to config.h - EWK2UnitTestBase.h should be included first in every EFL API test-case. I do not feel strongly about EWK2UnitTestBase.h, but wanted to take this chance to explain why I supported r135349. We should either follow this new practice going forward for future API tests as well or revert r135349 for consistency.

I think private header file is better than public header file.

I don't understand why you delete Ewk_Security_Origin via ewk_object_unref. AFAIK, ewk_object_unref is meaningful when item is based on EwkObject.

> Source/WebKit2/UIProcess/API/efl/ewk_application_cache_manager_private.h:38

Why do you use *_Get_* in struct name ? I don't know what does *Get* means here. Is Ewk_Application_Cache_Origins_Async_Context enough ?

Beside this struct is for internal usage, right ? If so, I prefer not to use _ in struct name.

We don't use . at the end of line in @param field.

private.h is required?

I am not sure whether we should add EWebKit2.h and Ecore.h
In other test cases, it was omitted because EWK2UnitTestBase.h include.

If then, please add static.

And const char XXX[] = is prefered.

How about reducing the duplication?

Ewk_Security_Origin also based on EwkObject.
But I'll change ewk_object_unref(static_cast<Ewk_Object*>(item));

This struct is for get application cache origins Callback. So I added *Get*.
And other struct name also "Get_Policy_Async_Data", "Get_Hostnames_Async_Data
".

Ah, my source was out of date. Ok, I got it.

assert?

const should not be used with local vars, due to coding style.

if you used own_ptr for 'webApplicationCacheContext' with adoption, manual delete would be avoided

Do we have to use "_" for private object names?

isn't it EwkApplicationCacheManager ?

inline is unneeded here, as function is defined in header. 
And again const member returns mutable pointer :(

LGTM except for a wrong description.

> Source/WebKit2/UIProcess/API/efl/ewk_application_cache_manager.h:73
> + * @return @c EINA_TRUE on successful request or @c EINA_FALSE on failure

This API returns *void*, not boolean.
