Java Development

Hi, Can you please tell me how to do unit testing my Blackberry application, is there any specific tool?

[simon_hain]

there is http://j2meunit.sourceforge.net/, i have never tested it though.
personally i use standard junit on classes that do not contain j2me/blackberry specific code, like webservice processing etc.

I'm also using normal junit tests and try to split my BlackBerry code from pure java code.

There a lot of simulator based frameworks around. An alternative to j2meunit would be B-Unit: http://sourceforge.net/projects/b-unittesting/ which is based on RIM CLDC application.

Hi,

Thank you very much for quick reply.

Can you please tell me how to work with bunit?

There was a session at last years BlackBerry developer conference about it.

Here are some of the points from the slide about bunit:

• Extend from “jmunit.framework.cldc11.TestCase”

• Return number of tests in constructor to parent

• Build a method  to call your tests

example:

public void test(int testNumber) throws Throwable
{
      switch (testNumber)
      {
        case 0:
          testDoSomethingThatShouldBeTested();
          break;
      }
}

Just use normal assert methods in your tests: 

see link

assertEquals("feetToMeters", 7.62F, result);

This is calling ‘assertEquals’ in our unit-test library, we pass the name of the test, the correct expected answer and the result of the function we’re testing.

the b-unittesting seems an interesting project, but not very active. 139 days ago the last activity, looks a bit suspect.
on our last test we were not very successful in using it.

+1 to using regular junit and separating as much code as possible into a pure java module.

 BlackBerry platform lacks reflection. Leaving the responsibility for enlisting tests to the developer. This is a lot of over-head and can lead to a stituation where tests don't get executed on "run all".

Compared to a desktop computer, the BlackBerry platform is slow. In XML parsing, the simulator can be 2 times or even 3 times faster than a Bold device. However, this is still slow compared to a desktop computer which is over 10 times faster than a Bold device in XML parsing.

On the desktop it's possible to write test harnesses using latest JAVA language syntax, and a much bigger API.

As an added bonus -which may or may not be important in a specific project- the pure java code is portable to other phones, webapp, desktop app, etc.

Cheers, Barak.

I want to test blackberry application and its completely RIM specific api.

Hi,

If not bunit means is there any other tool which i can do unit testing my blackberry application(Using RIM API)?

Please update me soon, as it is very urgent.

We used BUnit for specific test and had no problems.

That the project is not active isn't much a problem, it was build on a different unit-testing framework (jmunit) which still exists.

Give it a try.
