Junit test case return NULL error at the time of adapt resource on sling model based on delegation pattern

[N_haq]

Hi All,

I am facing NullPointerException on ButtonModelTest. ButtonModel class is created based on delegation pattern, which implements Button(core component class).

1 .Button Model class

2. ButtonModelTest

I am facing error at line 45, at the time of get the properties, even my json file is correct. 

Please help me find the solutions for junit test case for delegation pattern model classes.

Thanks in Advance.

Most of the cases of NullPointerException occur for the bad resource. In your test class check line no 39, you are getting the correct resource.

[N_haq]

line39 is correct, its not null.

[Sady_Rifat]

Actually, it's not about NULL. To see if the resource is correct or not check the next line. buttonModel is null or not.

[N_haq]

Yeah, its return NULL, that's why am not able to get any properties.

@N_haq 

Did you try adapting model with SlingHttpServletRequest?

buttonModel = context.request().adapt(ButtonModel.class);

@arunpatidar  Tried this approach but its not works for me. Still NullPointerException  at time of get the property of Button core class.

Is there any other way to do junit on sling delegation pattern?

Thanks.

Hi

Can you share your model and test class?

I cannot see the more than one adaptables in your model code, thats why I asked if you are following above or not
