Pojo matcher

[tricpod]

Hi,
is a Pojo matcher available somewhere?
I have a data object with 10 attributes.
In the expected and the invoked object are 8 attributes equal an 2 differs.
I don't need a complete printout of expected and the invoked object. This is
is a bit confusing and unclear.
What I like to have is an output like:
Objects are not the same: attribute a and b are different.
Is this already available?

If your object conforms to bean properties, you can use  
samePropertyValuesAs()

Hi,
with JMock1.2 it would probably work, if I had no list ...

one(mocked).method(with(aPropertyValuesAsMatcher(expected)));

@Factory
public Matcher<List<Entity>> aPropertyValuesAsMatcher(
    final List<Entity> expected) {
        return new SamePropertyValuesAs<List<Entity>>(expected);
}

some Ideas?

I'm confused. You want to match a list of entity objects?

Hi,

This should work:
one(mocked).method(with(aPropertyValuesAsMatcher(expected)));

@Factory
public Matcher<Entity> aPropertyValuesAsMatcher(
   final Entity expected) {
       return new SamePropertyValuesAs<Entity>(expected);
}

but not this:

one(mocked).method(with(aPropertyValuesAsMatcher(expected)));

@Factory
public Matcher<List<Entity>> aPropertyValuesAsMatcher(
   final List<Entity> expected) {
       return new SamePropertyValuesAs<List<Entity>>(expected);
}

I got
java.lang.NoSuchMethodError:
org.hamcrest.beans.PropertyUtil.propertyDescriptorsFor(Ljava/lang/Object;Ljava/lang/Class;)[Ljava/beans/PropertyDescriptor;
        at org.hamcrest.beans.SamePropertyValuesAs.<init>(SamePropertyValuesAs.java:27)

I know java.util.List is not a Bean ....

Yes. A matcher intended for a bean will not work with a list.

How about you tell us what you're actually trying to test, then we can  
help you.

Very nice. :-)

I want to compare a List of Entity. Your first idea was SamePropertyValuesAs.
But this don't works for list.

Something like:
If list size is the same check with SamePropertyValuesAs each entity.

How large is this list? If it's in a unit test, it should only be a  
couple of elements?
