Writing Junit test case for custom component, which is extended from core component

[rupaljain2408]

Hi All,

I have a custom hero component, which is extended from Image/v3 core component. The sling model is written using Sling Delegation pattern. I have overridden getSrc() and getAlt() methods in my sling model. 

How do we write Junit test case for these methods specifically ? Are these methods need to be covered, in general?

Any working example is highly appreciated.

Many thanks in advance!

Best,

Rupal

Hi @rupaljain2408 , 

please check the below code example given by @arunpatidar using delegation pattern.

Hi @Saravanan_Dharmaraj ,

Thank you for your reply. I checked this code from @arunpatidar , however he has not covered the core component's methods which were overridden in model class, for example - getActions() , getLinkURL(), getImageResource() etc. 

Do we not have to cover these methods from core component? 

Best,

Rupal

Hi @rupaljain2408 
This methods are not covered because they always return null.

If you want to cover just a code coverage, you can cover for null but I don't think so you will be able to test those overriden method.
