Issue in Mocking constructor

[vikas n]

Hi Johan,

This is regarding the issue that i am facing in mocking a constructor.

I have two different constructors for a class with different arguments as below (though it doesn't make sense) :

public ClassA(Long relationshipId) { this.relationshipId = relationshipId; } public ClassA(long relationshipId) { this.relationshipId = Long.valueOf(relationshipId); }

When i use the expectNew call as below to mock the object, it gives me the error as mentioned below

expectNew(ClassA.class,21L).andReturn(mockClassA)

Error:

org.powermock.reflect.exceptions.TooManyConstructorsFoundException: Several matching constructors found, please specify the argument parameter types so that PowerMock can determine which method you're referring to. Matching constructors in class com.att.osd.framework.core.model.relation.DimRelationship were: com.att.osd.framework.core.model.relation.ClassA( java.lang.Long.class ) com.att.osd.framework.core.model.relation.ClassA( long.class )

I read about this issue in the group and found that we can use suppressconstructor through one of your example stated below

suppress(constructor(EvilParent.class));

I am not able find the method "suppress(constructor())" can you please let me know where can i find it.

I couldn't find the method in MemberModifier, please refer to the attached image file.

I had to use anyObject(Shown below) as an aletrnate for the time being.

mockClassB.relateTo((ClassC)anyObject(),(ClassA)anyObject());

Also let me know if there is any other solution for the prob.

Thanks in Advance

Hi, 

If PowerMock cannot determine which constructor you refer to you need to provide the parameter types using this method:

expectNew(ClassA.class, new Class<?>[]{ Long.class }, 21L).andReturn(mockClassA);

Regarding your second questions it's stated in the docs that you should statically import methods from:

• org.powermock.api.support.membermodification.MemberModifier
• org.powermock.api.support.membermodification.MemberMatcher

I.e. the constructor(..) method you're looking for is located in org.powermock.api.support.membermodification.MemberMatcher.
