[MO-java-users] JDK 1.4 Logging Mocks

[Joel S. <joe...@ya...>]

Does anyone have mock objects for the
java.util.logging.Logger class?

Unfortunately, it's not an interface so I can't use
DynaMock.

[Joel S. <joe...@ya...>]

Well, I found one way, though I would certainly
welcome others' solutions.

Using NamingManager.setInitialContextFactoryBuilder()
as follows:


private Mock setupTestJNDI() throws NamingException
{
  final Mock mock = new Mock(Context.class);
  NamingManager.setInitialContextFactoryBuilder(new
InitialContextFactoryBuilder()
    {
      public InitialContextFactory
createInitialContextFactory(Hashtable
environment) throws NamingException
      {
        TestFactory.context = (Context)mock.proxy();
        TestFactory factory = new TestFactory();
        return factory;
      }
    });
    return mock;
}

[MO-java-users] Testing JNDI lookups

[Joel S. <joe...@ya...>]

How are people testing JNDI lookups and such? I see a
MockContext class in the mockobjects library, but
nothing about MockInitialContextFactory.

Ie. if a class calls new InitialContext() what do you
do to test it by controlling what it recieves?

I tried to write a quick and dirty mock for
InitialContextFactory but ran into trouble because
it's loaded in a different class loader. So even
setting a static variable on the class did not work.

So I'm wondering what other people are doing to test
this?

The Callable interface only defines three methods.  It's very easy to
implement.  More details are on the Wiki.

Ok, I roughly see what I should do. In the Wiki, I read:

-----
This is sugar for:

mock.add(
     new CallOnceExpectation(
     new NameMatcher( "methodName",
     new ArgumentMatcher( expectedArguments,
     new ReturnStub( result ) ) ) ) );
-----

But there's no add method anywhere in Mock.
I guess I could	use the expect(InvokableMatcher) method? But this
is available on CoreMock, not on Mock.

Any hint?

best regards,

Fr=E9d=E9ric

Re: [MO-java-users] A kind of "don't care" Mock?

[Nat P. <nat...@b1...>]

With the dynamic mocks you can write your own Callable objects to match
against any method or in some other custom manner.

Cheers,
            Nat.

[MO-java-users] MockObjects Framework for Web Components

[Tapi N. <ta...@ho...>]

Hello,

Can anyone suggest me MockObjects Framework for testing Web Components?

I tested Mockrunner which was quite nice and ok, but in my case it was not 
suitable
for all my purposes. I have to use third party vendor's Web framework where 
are e.g.
own Filter classes that are not implementing javax.servlet.Filter interface. 
That Web framework
contains also other incompatibilities that were not accepted by Mockrunner.

I also tried MockCreator but using it for testing Web Components requires me 
to
make Mocks for all Servlet API classes that my servlets, filters and tags 
are using.
So, maybe that is not quite elegant way to do it... at least there would a 
lot of Mocks to be
generated.

Can anyone explain me how you have used MockObject products for testing Web 
Componets?
Is there a possibilities to use e.g. Mockrunner with some other Mock tool or 
how should I handle
testing with Mocks? I really like to use this technique.

Thanks,

tapi

[MO-java-users] A kind of "don't care" Mock?

[Frederic D. <fre...@ac...>]

Hi all,

I must confess I haven't thoroughly searched through either Wiki,
the lists or the source code (Flame disclaimer :) )

Is there a way to create a mock with a default 'I don't care'
behaviour for most of the methods?
What I mean is that, for some tests, there might be a bunch of
methods called, for which I don't want to set expectations (because
sometimes I don't know which methods will be called, how many times,
..., or if the mock-proxy is temporarily handled to an outside object
for which I don''t have the source code, or I just don't care to
provide an 'implementation' (hashcode, toString, ..)).
For those methods, I'd just like to set a global default behaviour:
- match any call, with any args (or no args)
- return a default value (true or false for boolean, 0 for numeric
values, null for objects) (with this default value that could be
changed).

but still to be able to set expectations on methods I care.

In the same way, is there a way to say "this method will be called,
I don't care how many times, just return always this value" ?

Thanks!!

Regards

Frederic

[MO-java-users] ConstraintsMatcher for more than 3 input arguments? C.args()?

[veny <ve...@p2...>]

Hi all,

How to use ConstraintsMatcher to verify method that has 4 input parameters?
Or is there any other way to do that?
By the way, how to use C.args(), C.args(Constraints, Constraints),
C.args(Constraints, Constraints, Constraints) methods?

Thanks.

At that point you might as well write your mocks by hand -- the 
expectation library will help you do this. We have some ideas about 
dynmically mocking classes, but haven't had the time to patch them in.

[veny <ve...@p2...>]

Hi Steve,

Thanks for your reply.

What i actually meant was that i want my mock class to take in expectation
of a method being called and verify whether the method has been called at
the end (i.e. when .verify() method is called). I understand
dynamic.Mock.expect(String methodName) does that. I cant use dynamic.Mock as
the dynamic.Mock can only mock an interface, but i need to mock a class
implementation.

So my issue is how to write my mock class that so that it can perform a
function like dynamic.Mock.expect(String methodName)?  Any idea?

Thanks lots.

If you mean when writing a mock object using the dynamic libraries, then
no. The Dynamic Mock will do the work. If you mean, when writing your
own mock objects from scratch, then you should write some kind of
expectation, but how you write that is up to you.

As you have noticed, you cannot mock classes.  For your information,
java.util.List is an interface, not a class.  ArrayList and LinkedList
are actual implementations of the List interface.

To mock concrete classes, you have to resort to the old way:
public class ObjectUnderTest {
    public void method(Object arg) {
         // Do something
    }
}

public class MockObjectUnderTest extends ObjectUnderTest implements
Verifiable {
    private ExpectationValue expectedArg = new ExpectationValue("arg");

    public void setExpectedArg(Object arg) {
        expectedArg.setExpected(arg);
    }

    public void method(Object arg) {
        expectedArg.setActual(arg);
        // Might call into super class to execute the code for real, or
        not,
        // depending on your needs.
    }

    public void verify() {
        // This asserts that all Verifiable objects in this class have
        their
        // verify() methods called, and any exceptions thrown up the
        // call stack
        Verifier.verifyObject(this);
    }
}

That is why most programmers and designers recommend coding against
interfaces.  This helps because you can then send in a mock
implementation.  DynaMocks are simpler to setup than old-style Mocks.

I sure hope that helps !

If you have other questions, do not hesitate !

[MO-java-users] creating a dynamic mock error - com.packagename.classname is not an interface.

Hi all,

I've been using DynaMock to create mock class from interfaces. It works
great. However, when i tried to mock my classes, there's always this error:
"com.packagename.classname is not an interface". I've tried to mock java
class (e.g. java.util.List), it works. But why creating of mock of my custom
class doesn't? Any idea?

Thanks.

[MO-java-users] Re: [MO-java-dev] expectAndReturn, matchAndReturn. how to use?

[Francois B. <fb...@us...>]

Hello Veny,

Here is a bit of information for you:
expectAndReturn()
    Expect a call to the named method using the specified argument or
    arguments, and return the specified value.  It is possible to also
    throw an Exception instead by using expectAndThrow().  As you have
    guessed, expectAndReturn() will fail the verification if the method
    has not been called.

matchAndReturn()
    Stub out a method call.  This would be useful in the case where you
    will be calling a method, but do not care if the method is called
    once, twice or no time at all.

ConstraintMatcher
    It is possible to specify constraints on the parameters that are
    received.  Let's say you are mocking a List.  Lists have a method
    named Object get(int index).  It is possible to ask the
    expectAndReturn method to assert that the method is called with an
    appropriate parameter.  An example will help:
Mock mockList =3D new Mock(List.class);
List list =3D (List)mockList.proxy();

mockList.expectAndReturn("get", C.eq(3), "returned object");

// This is where the domain methods call upon the mock
classUnderTest.method(list);

mockList.verify();

Given the above, the following implementation will fail:
public void method(List list) {
    int index =3D 4;
    this.object =3D list.get(index);
}

It will fail because the expectAndReturn() method expected a single
parameter, and it must have been equal to 3 (C.eq stands for
ConstraintMatcher Shortcuts.equals(3)).

Given the above too, this implementation will fail the verify() stage:
public void method(List list) {
}

The Mock expected the get() method to be called with 3 as an argument,
but did not receive it.

Finally, if you overload your methods, the same principles as Java apply:
interface User {
    addBilling(double x);
    addBilling(long x);
}

Mock mockUser =3D new Mock(User.class);
User user =3D (User)mockUser.proxy();

user.expect("addBilling", C.eq(new Double(13.2d)));
user.expect("addBilling", C.eq(new Long(17l)));

classUnderTest.do(user);


public void do(User user) {
    user.addBilling(17);    // Passes.  Java calls addBilling(long)
    user.addBilling(13.2f);    // Passes.  Java calls addBilling(double)
}

As for your last question, if the method that you expect a call upon
accepts a single parameter, and you want to assert equality, Mock
implementations allow a shortcut.  Instead of this:
user.expect("addBilling", C.eq(new Double(13.2d)));

You can do this instead:
user.expect("addBilling", new Double(13.2d));

Notice that the C.eq() was removed.  We are expecting equality, and this
will assert it just fine.

For documentation, you can try http://www.mockobjects.org/.  This will
bring you to the MockObjects Wiki.  There is information on the wiki
about the framework.  Not everything is documented, but a good bit of it
is available.

Have a nice day !

[MO-java-users] expectAndReturn, matchAndReturn. how to use?

[veny <ve...@p2...>]

Hi all,

I am new to mockobject and looking through the DynaMock class.
Could somebody give me some idea, what does the following methods in
com.mockobjects.dynamic.Mock class do?

expectAndReturn(java.lang.String methodName, ConstraintMatcher args,
java.lang.Object result)
expectAndReturn(java.lang.String methodName, java.lang.Object
singleEqualArg, boolean result)

I understand the above methods is setting the return value for the named
method. But some questions:
- How does ConstraintMatcher works?
- For the second method, what is the use of parameter singleEqualArg?
- These methods are name expectAndReturn, does it implies that if the named
method is not called, it will throw an error? - How bout if the codes have
methods overloading, how does expectAndReturn know which method i am
referring to?

matchAndReturn(java.lang.String methodName, java.lang.Object result)
How is this different from expectAndReturn?

The javadoc has rather limited explanation, any recommendation to sites that
have sample or more detailed explanation?

Thanks lots.

If there is no explicit overloaded expectAndReturn method for float results,
create a new Float object to wrap the primitive value.  The underlying proxy
API will "unbox" the object to a primitive float when the call to the mocked
method returns.

E.g.

myMock.expectAndReturn( "methodName", new Float(1.0f) );

Cheers,
            Nat.

[MO-java-users] Return float value with dynamic mock object

[veny <ve...@p2...>]

Hi all,

I am new to mock object.
I am writing some test using DynaMock and wondering what is a good practice
in returning a float value using Mock.expectAndReturn(String methodName,
Object obj) method.

Hope to hear from you soon.

Thanks.

[MO-java-users] Re: [MO-java-dev] Is it possible to verify call sequence between two or more Mocks ?

[Steve F. <st...@m3...>]

There's a constructor in Mock (for the release) and CoreMock (for the=20
CVS head) that allows you to pass in the collection that gathers=20
expectations. I think you can achieve what you want by making both mock=20
implementations share a common expectation collection.

We have some ideas about how to specify precedence but we have to do=20
some more clean-up first.

Re: [MO-java-users] How to set expection for a method with a lot of arguments

[Nat P. <nat...@b1...>]

Read this documentation for more info about constraints:
http://www.mockobjects.com/wiki/ParameterConstraints

Although I would identify methods with lots of parameters as a "code smell"
that indicates that you should refactor the parameters into a new class of
object.

Cheers,
       Nat.

Subject: [MO-java-users] How to set expection for a method with a lot of
arguments



My question is how to set expection for a method with  a lot of arguments in
a mock object.

For example, there is a Timer interface:

public interface Timer
{
    int getTime( Type1 arg1, Type2 arg2, Type3 arg3, Type4 arg4, Type5
arg5 );
}

In the following test code:
   Mock mockTimer = new Mock(Timer.class);
   mockTimer.expectAndReturn("getTime", ???);

How to set the above expection. How to express that the getTime() can be
invoked 5 times for example.

Another question is:
  What is the difference between C.args() and C.eq(). How Constraint class
and ConstraintMacher class are used.

Thanks

[MO-java-users] How to set expection for a method with a lot of arguments

[Guofeng Z. <guo...@vi...>]

My question is how to set expection for a method with  a lot of =
arguments in a mock object.

For example, there is a Timer interface:

public interface Timer=20
{  =20
    int getTime( Type1 arg1, Type2 arg2, Type3 arg3, Type4 arg4, Type5 =
arg5 );
}

In the following test code:
   Mock mockTimer =3D new Mock(Timer.class);
   mockTimer.expectAndReturn("getTime", ???);=20

How to set the above expection. How to express that the getTime() can be =
invoked 5 times for example.

Another question is:=20
  What is the difference between C.args() and C.eq(). How Constraint =
class and ConstraintMacher class are used.

Thanks

RE: [MO-java-users] How to express an expected invocation using d ynamic mocks?

[<DeS...@em...>]

Nat,

Thanks. It worked.

However, my main confusion was that I was looking for an API where I could
specify an expecation on a method with a specific signature (argument list).
How do you handle expectations on overloaded methods, for example, what
would your write if the Pluxie interface would have read:

public interface CallSemantics {
  Pluxie configure(Pluxie pluxieToConfigure);
  Other  configure(Other  otherToConfigure);
}

How does the framework distinguishes the expectations between the overloaded
methods?
