Re: [Rmock-users] RMock and Java Reflection API

[Ziem, T. <Tho...@t-...>]

Hi Daniel,

that sounds good.

What's your suggestion for non-default constructors?
Perhaps another function like that:

Object getInstanceByConstructor(Constructor constructor)

The variables "name" and "className" should of course be the same, my bad.

Re: [Rmock-users] RMock and Java Reflection API

[Daniel B. <dan...@gm...>]

Hi Thomas,

Javas reflection classes are generally not "mockable".

What I have done successfully in several project was to create a
facade with the needed functionality.

public class ReflectionStuff {
Class getClassByName(String name) {
try {
return Class.forName(className);
} catch(EveryExceptionKnownToMan e) {
//handle nicely by throwing e.g. a runtime exception
}
}
Object getInstanceByName(String name) {
 return getClassByName(name).newInstance();  // You need to catch a
few more here :-P
}
}

Then you can mock that class (or create an interface in the same
manner if you prefer that) and inject into the class you are testing.

A good bonus is that you will handle all of the meaningless exceptions
Java might throw when reflecting in one place in the code.

Did that help?

Cheers
Daniel

[Rmock-users] RMock and Java Reflection API

[Ziem, T. <Tho...@t-...>]

Hi all,
 
I want to test a class which loads classes using the Java Reflection
API:
 
Class.forName(className).newInstance();
 
The value of className comes from a configuration property.
Is there any way that the class under test uses a mocked object instead?
 
Thank's,
Thomas

Re: [Rmock-users] method of class under test requires a session

[Daniel B. <dan...@gm...>]

Hello Mark!
Thanks for the somewhat "abstracted" question ;-)

You generally want to apply the "Hollywood principle": "Don't call us,
we'll call you".

If the class that needs the session creates it, you generally have a
problem when you want to test the class. You then have a hardwired
dependency on that constructor.
Instead, you want to be able to configure the class with the session
(a set-method or a constructor argument). Preferably, the session
object is an interface, and when you test the class, you mock that
interface and pass it to the class.

Ok, sooner or later you actually have to instantiate something, but
that is usually best left to some dependency-injection framework, like
Spring, Pico-container or other.

Cheers
Daniel

[Rmock-users] method of class under test requires a session

[Mark F. <mar...@gm...>]

Java 1.4.2, Junit 3.8.1 rMock 2.0

I'm a newbie to rMock and unit testing in general at this level so
forgive me for asking what are probably simple questions but I have to
learn somehow :)

I have a method that I'd like to test that requires that a session to
a back-end document management system first be established.  I'd
really like to test the method in isolation, without requiring an
active session but I can't figure out how to do it.   I can post the
code if necessary.  I tried mocking the session object but since the
class under test is retrieving the session and is not mocked it just
throws a npe.

I'd also appreciate any pointers to good references on unit testing,
especially using mock objects and especially using rmock.

Thanks,
-Mark

Re: [Rmock-users] am I asking to much from rMock?

[Daniel B. <dan...@gm...>]

Then I think you should just create an instance of it:

IDoctypeSBO sbo = new IDoctypeSBO();

set up the expected mocks:

IDfSysObject mockObj = (IDfSysObject) mock(IDfSysObject.class);
mockObj.setACLName("newacl");
mockObj.setACLDomain("newdomain");

call the sbo-method after startVerification();
sbo.changeACL("docbasename", mockObj, "newdomain", "newacl");

Then rmock will verify that sbo made those calls that you expect (i.e.
thet set methods).

I also removed the empty try catches and moved the exception to the
test-method, since that code at best is unnecessary, and in the worst
case it will hide an exception thrown.

The test:

     public final void testChangeACL()  throws DfException {
               IDoctypeSBO sbo = new IDoctypeSBO();

               /* Set up Mock objects */
               IDfSysObject mockObj = (IDfSysObject) mock(IDfSysObject.class);
               /* Expectations */
               mockObj.setACLName("newacl");
               mockObj.setACLDomain("newdomain");

               /* Verification */
               startVerification();
               sbo.changeACL("docbasename", mockObj, "newdomain", "newacl");
       }

Daniel

[Rmock-users] am I asking to much from rMock?

[Mark F. <mar...@gm...>]

rMock with JUnit 3.81 and Java 1.4.2

I have an implemented method of an interface that changes the ACL of
an object in a document management system:

void changeACL(String docbase, IDfSysObject reference, String
aclDomain, String aclName) throws DfServiceException

I have a test method:

        public final void testChangeACL()  {
                /* Set up Mock objects */
                IDfSysObject mockObj = (IDfSysObject) mock(IDfSysObject.class);
                IDoctypeSBO sbo = (IDoctypeSBO) mock(IDoctypeSBO.class);

                /* Expectations */
                try {
                        sbo.changeACL("docbasename", mockObj,
"newdomain", "newacl");
                        mockObj.getACLName();
                        mockObj.getACLDomain();
                } catch (DfException dfe) {
                }

                /* Verification */
                startVerification();
                try {
                sbo.changeACL("docbasename", mockObj, "newdomain", "newacl");
                        assertThat(mockObj.getACLName(), is.eq("newacl"));
                        assertThat(mockObj.getACLDomain(), is.eq("newdomain"));
                } catch (DfException dfe) {
                }
        }

The problem is that the assertions fail with:

com.agical.rmock.core.exception.RMockAssertionFailedException:
ASSERTION FAILED!
<null>
does not pass the expression:
<eq(<newacl>)>
...

I think this is because mockObj.getACLName() is returning null because
it is not affected by the changeACL method.  How can I make the
changeACL method have an affect, i.e. change attributes of the mocked
object?

Re: [Rmock-users] A mock as an attribute of another mock

[SMITH N. <nei...@un...>]

Thanks for your rapid response!

I'm sorry, I didn't give you enough information... But it's solved!

In fact, the getCourse() is to create another object (it's a bit
complicated...). If a course is full, it creates a
RegistrationWaitingList object (which is quite similar to a
registration). This is then used to keep a waiting list of
registrations. This object is always created, because I test if the
person is already registered to the course (in waiting list or not). So
this should not interfere with my tests.

I when wrong with the setCourse(course1)... It was there because I was
trying to set my course to my course mock... That should be done by
using the bit of code you provided, I understand that now.


Thanks again!!!

Best regards
Neil.

There is a way to do this. In your case I'm not sure, I would have to
see the testcase and perhaps some source but from your error it looks
like you've got an automatically created mock back from one of the two
getCourse calls and that one is used instead of your manually created
"course1" mock.

>From your expected setCourse(course1) invocation I suspect that you
might have expected the value to actually be set as a property and not
only expected but there is no way I can be sure.

If I'm right you could solve it in one of two ways:

1)

Course course1 =3D (Course)mock(Course.class);
Registration registration =3D (Registration)mock(Registration.class);
registration.getCourse();
modify().returnValue(course1);

startVerification();

2)

Registration registration =3D (Registration)mock(Registration.class);
Course course1 =3D registration.getCourse();

startVerification();


Both are equivalent. In the second case RMock automates
mock(Course.class) and modify().returnValue(course1);

This a bit of a stab in the dark since I lack some information but I
hope it helps. /Joakim Ohlrogge

[Rmock-users] A mock as an attribute of another mock

[SMITH N. <nei...@un...>]

Hello!

I'm having a little trouble working this one out and I don't know if it
is possible.

Here is what I have:
3 classes, Person, Registration and Course

Registration concerns a Course (1 and only 1)
Person has a set of Registrations


When I test my Person class, I want to have a mock of my Registration
classe to isolate it properly, but to do that, I also have to mock my
Course classe, so I have a mock (mockReg) that has a property of Course
type that contains a mock.

I hope this is all clear up to now...

When I test my Person class, I'm having touble setting up the
expectations on my Course mock.
For example

        mockCourse.countRegistrations();
        modify().returnValue(0);

And when I run the program, I get the error

com.agical.rmock.core.exception.UnexpectedInvocationException:=20
UNEXPECTED!
No expectation matched: course1$.countRegistrations()
-----------------------------------------------------------------
3 expectation(s) have not yet been matched
(indicated by '->' in the listing below)
-----------------------------------------------------------------
        Unordered section:root {
             Unordered section:main {
                  1(1)
registrationInt1.setRegsistered(eq(<ch.unifr.sdis.isweb.business.Sportsm
an@5cfa9339>))
                  1(1) registrationInt1.setCourse(eq(<course1>))
->                0(1) course1.getMaximumParticipants()
->                0(1) course1.countRegistrations()
->                0(1) course1.addRegistration(eq(<registrationInt1>))
                  1(1) registrationInt1.getRegsistered()
                  1(1) registrationInt1.getRegistrationDate()
                  1(1) registrationInt1.getRegistrator()
                  2(2) registrationInt1.getCourse()
                  1(1) registrationInt1.getCourseDetail()
                  1(1) registrationInt1.getPhone()
                  1(1) registrationInt1.getEmail()
                  1(1) registrationInt1.getNote()
                  1(1) registrationInt1.getRentedEquipment()
                  1(1) registrationInt1.getRegistrationDisciplineLevel()
             }
             Unordered section:defaults {
             }
        }

As you can see, my course1.countRegistrations() is not matched, and the
course1$.countRegistration() is an unexpected invocation...

How can I setup the expectations for my mock in the mock? Is there a way
to do this or not?


Thanks in advance!

Take care
Neil.

Re: [Rmock-users] How to mock an object without a junit test

[Joakim O. <joa...@ag...>]

Hi Markus,
Thanks for your questions I feel I don't answer much but rather ask
more questions. I try to communicate where I come from when reading
your questions. I want to help but I fear I don't have much experience
with what you want to do so I try to half tell you what I do and half
comment on what I think can be done with RMock to meet your needs
whether I believe it's a good idea or not. I hope this helps some and
feel free to ask more.

Interesting, we would really like to know how the tool is perceived by
others so if you want to share what you've found on the list or
offline we would be very happy to hear about it.

>From that description and the code above I can not see why creating
the mocks from a TestCase would be a problem. I'm sure I've missed
something important such as what you are using to inject the
dependencies. Personally I use RMock a bit inside out compared to what
you want to do. I test interactions between objects "inside" the
system instead of putting the mocks at the border of the system. This
is what RMock was designed to do but that doesn't mean it cannot be
used for other things.

The proxy class is used behind the scenes in RMock, it's not intended
to be used directly.
Simply put, RMock does not support what you want to do in any simple
way. We toyed around a bit with the framework for JUnit 4 wich by
design sort of requires what you're requesting. We managed to do it
but it required a bit of voodoo and quite frankly was a bit fragile
(due to RMocks internal design centered around a hub)

The order of calls should be unimportant unless you specify to use an
ordered section.
By using some obscure features in RMock
(forEach(expression).in(all.methodsOf(class))...
and a custom action that would print out the calls you could accomplish this.
However, I think that rMock is the most useful when driving the design
of units with TDD. I found that retrofitting RMock to test an already
built system or testing something that is bigger than one or a few
classes at a time tends to create more hedaches than be of help.

We use as a rule of thumb that if you need more than 10 expectations
to test something with rMock you're testing too much at the time.
Sometimes that means breaking stuff up with the single responsibility
principle as a guideline. Of course feel free to ignore this rule, the
important thing is that your test communicates your intentions clearly
and that you feel that RMock is a better choice than some other tool
you can think of for the job.

Did you check out the users guide?
http://rmock.sourceforge.net/documentation/docbook/pdf/rmock.pdf

It is very reference oriented. Please share what type of documentation
would help you get started and we will see what we can do (although we
have had less time than we would have liked for RMock lately for
private reasons mostly)

[Rmock-users] How to mock an object without a junit test

[Baumgartner M. <Mar...@sw...>]

Hi all,

I started an evaluation of mocking tools comparing rMock and jMock. What
I have seen - and understood - so far is very interesting, but still
little.

Now we are trying to mock an object without a junit suite, that is
without extending RMockTestCase

The motivation is this:=20

the program is calling a backend system through a Connection-object.
This 'border'-object we want to mock and then stuff it into objects
using Connection via dependency injection


MockConnection mockConnection implements IConnection

Actor  actor =3D new Actor(mockConnection);


I found a Proxy class in your library, but no hint how to use it. I saw
this was possible in jMock, so I guess this is possible with Rmock too.


The next question is based on this:=20

When the backend system is changing, in particular the form or order of
replies, we have to update the mock (otherwise we would mock 'the
past'). Because there is a huge number of request/reply pairs, we must
automate this. The idea is to have a switch like "record" that would
write out the requests and its replies, from where we could generate a
new Mock.=20

Did anybody try this and has a suggestion?


Thanks for help

Markus

P.S. I googled the Internet for hours to find more documentation or
examples, but didn't find anything. The documentation is addressing
people that know a lot how the program works, but for newbies it is not
suited (I learned how to mock with jMock documentation, which is not
good as well , but a bit better. That's a pity because it does not ease
the access to the tool. (I even started to write my own documentation
including a testsuite with examples showing the different use cases and
I guess such a suite with simple example might be handy for other users
too. At least here it was...)

Is there anybody out there, who has or found some more documentation?

Re: [Rmock-users] Unique Ids

[Daniel B. <dan...@gm...>]

Hello!
There is now a RMock 2.0.2 in the maven2 repo. Try that one and get
back to us if anything fails. Please disregard the 2.0.1, I was a bit
trigger-happy there. ;-)

If you want to download it directly it resides at:

http://www.ibiblio.org/maven2/com/agical/rmock/rmock/2.0.2/

We're sorry for the embarrassing delay in this matter. One good thing
is that we've made great improvements to the maven deployment process,
so hopefully future updates will arrive more frequently.

Cheers
Daniel

[Rmock-users] Unique Ids

[David C. <dc...@al...>]

We've recently started running into a errors because we don't have unique ids 
specified.  I think the default mock() method should simply choose unique ids 
(by appending a sequenceNumber to them).

David.

[Rmock-users] RMock 2.0.0 is now in the Maven2 repository

Hello all!
RMock 2.0.0 is now in the Maven2 repository!
We had some problems with the upload process, but it seems to be fixed
now. Hopefully we will be able to push out new releases more easily
and frequently in the future!

Please, let us know if you have any problems.

Cheers

Re: [Rmock-users] arg checking based on contents not equals

[Joakim O. <joa...@ag...>]

Hi David,

No, there is no such expression yet. If you create one we would be happy for
to include it in the next RMock delivery.
I have also thought about creating an "equalByToString" expression that
would consider two objects to be equal if their
toString methods return the same string. I think that could save some
HashCode and equals implementing.

It's nice to hear that users out there are creating their own expressions
and pushing the framework.
Let us know if you come up with other ideas that would make RMock Easier to
use. Sometime in the not too far future
I hope we will lbe able to spend more time on RMock than we can currently do
for different reasons.

[Rmock-users] arg checking based on contents not equals

[David C. <dc...@al...>]

One thing I've run across a few times is this situation.

I'm going to pass an argument to a mocked service, and the equals method 
doesn't accurately work for the test.  In my current case, it's a "reference 
object" so equality is based on an ID, but what I care about is that certain 
fields are set "just so".

Now, I've managed to write my own Expression that I can use that works for the 
specific case, but it seems to me that there ought to be some Constraint that 
would work by comparing named fields and/or properties.  Is there such?

Thanks
David
