SmartFoxServer unit testing

[hoangdoanh]

Hi Lapo

Now, I need to implement unit test of SmartFoxServer extension(unit testing on server-side). Do you have any solution for that? Suggest me please !

Kind regards,
Hoang Doanh

Hi Lapo, on the topic of Unit testing. I am trying to create a unit test for an extension method in a class that extends the BaseClientRequestHandler class with no luck. I am attempting to use PowerMockito to spy or partially mock this class to make the trace() and send() methods do nothing. This same practice is working fine when I mock the User class to mock getUsername(), but for some reason Mockito cannot mock the BaseClientRequestHandler class or any other SFSExtension class for that matter. What am I missing?

[Lapo]

Hi,
I am not familiar with PowerMockito. Are you getting any specific error?

Thanks

I am using Mockito version 3.1.0 and PowerMock version 2.0.2. When I try mocking the User class using the following syntax:
User user = mock(User.class);
This works fine for me with no errors. This also works with SFSObject and SFSArray. When I try a similar approach to mocking the class BaseClientRequestHandler:
BaseClientRequestHandler handler = mock(BaseClientRequestHandler.class);
I get the error below. I have also tried this with SFSExtension class with similar results, I also have attempted using PowerMock's "spy":
BaseClientRequestHandler handler = spy(BaseClientRequestHandler.class);
and with this a similar resulting error occurs. I have found documentation online stating that mocking an abstract public class should be no problem for PowerMock/PowerMockito.

[Lapo]

Given the the NoClassDefFoundError in the stack trace it sounds like you're missing some dependencies at runtime.
Make sure that your test classpath includes the SFS2X/lib/ folder so that all jars in there can be found.

Hope it helps

[linquest]

As far as I can tell, I am including the SFS2X and SFS2X-Core folders as class paths and they seem to be resolving okay. To follow your logic, do classes like SFSObject and User reside in SFS2X-Core while BaseClientRequestHandler resides in the SFS2X folder instead? If that was the case I guess that could make sense then that the former two classes are mocking correctly while BaseClientRequestHandler seems to be missing.
Thank you for your help.

[Lapo]

The error is complaining about about classes outside the sfs2x core jar files.
Like this --> org/slf4j/Logger

I am including the SFS2X and SFS2X-Core folder

There aren't any folders with those names.
You need to make sure that the classpath includes the "SFS2X/lib/*" including the star symbol, which tells the JRE to look for all the jar files in the folder.

Cheers
