Help please with complex JUNIT test cases across classes

Fri, 9 May 2008 03:54:58 MDT

Hello,

I have been thrown rather into the deep end and asked to debug and create test cases for an application. I'm completely new to JUNIT, and I'll be honest my Java is not that great beyond the basics. I know the methods I want to test, and the results I want to prove. However, it's the coding that is the problem for me. I learn best by example rather than by explanation, and I also suspect the fact I'm partially sighted is not helping issues when it comes to spotting errors. The application itself is at Index of /trending

That folder also contains my checklist of things to test and an explanation of the classes in the application. I've looked for quite a while at JUNIT examples, and even had someone send me an a...

How to remove indents from xml?

Sat, 3 May 2008 14:52:32 MDT

I have a xml like this:

<?xml version="1.0" encoding="UTF-8"?>
<view>
<help>
<block>No.1</block>
<device>USB</device>
</help>
</view>

How could I output the xml to :
<?xml version="1.0" encoding="UTF-8"?><view><help><block>No.1</block><device>USB</device></help></view>

The reason to output like this is to make the xml comparison passed.
I use org.custommonkey.xmlunit.XMLTestCase.compareXML to compare two xml string, one from Java code, the other from C# code. Now, since there are new line and whitespaces embedded in the Java generated XML, the comparison alway...

Automatic Test generation for Java

Fri, 2 May 2008 03:00:27 MDT

Hi all,

Say i have a huge applicaiton. The problem is as follows :-
1) unfortunately there is no unit test cases ie junit written.
2) Now if some part of the project is changed. developer gonna check the whole application to know if everything it working and none is broken.
3) So i was wondering if there is any tool which can be used to generate the test cases so that when i run after some changes in the application i get to know that my code has broken or if entire application is working fine.

The application i am talking about is not an web app or j2ee app. its an corba ,swing app, with use of some telnet and snmp as well.

thank you

Sample application for jboss

Thu, 1 May 2008 13:22:26 MDT

Hi
I want to test a sample application on Jboss which will affect JVM utilization. i.e. the application must make best use of the JVM and underlying CPU cores. I am performing this on Linux setup with Jboss 4.0.2.

So can anyone help me regarding this. I need an application like Trade6 used in case of Websphere for better performance.

Use of interfaces for unit testing

Wed, 30 Apr 2008 18:06:23 MDT

Hi. I'm thinking that any class of reasonable complexity should be 'interfaced out', so that it can be completely removed as a dependancy in unit tests, and then tested itself in as much isolation as possible.

Eg, I have a session bean which does some stuff. It uses a validation class to do a load of validation. Would it make sense to make the validator implement an interface so that i can test it seperately, significantly simplifying the unit tests for the session bean?

The reason I ask is that thinking like this could produce alot of interfaces, but I think that the extra overhead of maintaining these interfaces will be massively outweighed by the benefits to unit testing.

I'd appreciate any comments

How to test a javabean

Tue, 22 Apr 2008 11:31:46 MDT

I have a javabean class. I should add Junit test class for that. I am wondering how to add test cases for getter setter methods. Evenif I add, will that be a proper testing of Java? Or are we just testing the java compiler by doing this?

Thanks

Newbie question on JMock

Tue, 22 Apr 2008 05:11:45 MDT

Hi,

I have just come across JMock and haven't quite got the hang of it yet.
I have a class called JabberAccountManager. It has a few methods that perform account management operations. Every method internally creates an object of type XMPPConnection (which is a part of an XMPP library)

Now, I want to mock the Jabber server so I need to create a mock XMPPConnection object, but my problem is that the class I need to test and the class I need to mock are tightly coupled. I cannot de-couple these since there are a lot of issues involved.

Could someone please explain to me how to go about using JMock in a case like this?

Thanks,
Neha.

wrong @BeforeClass behaviour

Tue, 22 Apr 2008 03:28:23 MDT

Hi,

According to the javadoc I found at http://api.dpml.net/junit/4.2/org/junit/BeforeClass.html, (http://api.dpml.net/junit/4.2/org/junit/BeforeClass.html,) "The @BeforeClass methods of superclasses will be run before those the current class."

I've got a JUnit test called AdminFacadeBeanTest which extends AdminFacadeBeanTestBase, and both have a method with a @BeforeClass annotation.

According to the javadoc I found at http://api.dpml.net/junit/4.2/org/junit/BeforeClass.html, (http://api.dpml.net/junit/4.2/org/junit/BeforeClass.html,) "The @BeforeClass methods of superclasses will be run before those the current class."

Conceptual questions concerning Unit tests

Tue, 22 Apr 2008 03:06:23 MDT

Hello,

Im just trying to setup an unit testing environment in the project im working atm.

I just evaluated the different approaches of mock objects and the idea behind JUnit and the in-container approach of Cactus and i still have some questions about it...

If i want to test my DAO classes which retrieve information from a persistent environment (in this case DB) i use a datasource that i lookup through JNDI. JNDI however is a naming service provided by the container. One thing i want to avoid is to create mock objects for all the services, as this would result in lots of mock objects to maintain.

The in-container approach seems to be more logic to me. What do you guys think?

How to capture unix cpu and memory usage....

Tue, 15 Apr 2008 13:12:58 MDT
I have been tasked with load testing an application on an Unix machine, let's refer to the application as BASE. I will be writing a load simulator class (in java 1.6) to load the application from a Windows XP machine, let's refer to this application as TESTER.

Is there a straightforward way to get the memory usage and cpu % of BASE from within the TESTER code? This will allow me to capture data conveniently in terms of load units generated and the associated cpu usage and memory usage.

I am totally new to testing but, as usual, have to have this finished quickly. Any pointers, suggestions, or links would be appreciated.

From my initial research there doesn't seem to be a straightforward way to do this ...
