java.lang.AssertionError:
Expected: a string containing "... text=Ç..."
     got: "... text=Å..."

My immediate reaction was the encoding used by the JVM. Setting the “file.encoding” system property to UTF-8 did not help. Running the ant based tests in remote debugging mode also confirmed that the two strings were indeed different.

Since the tests used Cobertura for code coverage, the next step was to disable cobertura. Cobertura manipulates the generated byte code to add logging statements for code coverage. Still the same error.

The hidden gem seemed to be the -encoding java compiler flag. Setting it to UTF-8 fixed the problem.

So the next time you have something fail because of an encoding issue, it could just be the compiler encoding and not just the encoding used in the runtime!

All you need to do is execute:

ant -listener com.google.code.ant.growlnotify.GrowlListener

And you’ll need is the growlnotify binary somewhere on your path, this is bundled with the Growl binary dmg.

After reading a lot of noise from fellow ThoughtWorkers in the recent past about Mockito. I decided to give a yet another mock framework a try.

Here’s what I ended up writing:

public class RecorderLauncherTest extends TestCase {

	private RecorderListener listener;
	private RecorderLauncher launcher;
	private TestRunner runner;

	protected void setUp() throws Exception {
		super.setUp();
		listener = mock(RecorderListener.class);
		runner = mock(TestRunner.class);
		launcher = new RecorderLauncher(runner, listener);
	}

	public void testNotifiesListenerWhenLauncherStarts() throws Exception {
		launcher.launch();
		verify(listener).start();
	}

	public void testNotifiesListenerWhenExecutionFails() throws Exception {
		stubVoid(runner).toThrow(new RuntimeException()).on().run();
		launcher.launch();
		verify(listener).start();
		verify(listener).error();
	}

	public void testNotifiesListenerWhenExecutionCompletes() throws Exception {
		launcher.launch();
		verify(listener).start();
		verify(listener).finish();
	}

}

What’s even nicer is that it’s actual code and not strings, and refactoring tests do not break my mocks.

Good bye expect-run-verify, hello run-verify.

This looks, and reads far better than the JMock syntax, and it was love at first sight; I’m test-infested now. If you have not tried mockito as yet, I’d recommend that you do. I’m sure you’ll love it too.

#!/bin/bash
find -iname "*.jar" | xargs -i unzip -l {} | less

In case you are new to less, here’s how you navigate:
1. To find a particular class say com.xyz.abc.MyClass, you type:

/com.xyz.abc.MyClass

2. To find what jar contains this class, you type:

?Archive:

A lot of folks use *nix and the existing CCTray is not much help.

If you wish to use this pre-alpha release, feel free to write back. It’s not all that configurable, so you have been warned

Oh, yes, BTW this release depends on issue #899 of CCNet dashboard, and issue #118 of CC.rb. You can vote for these issues to be resolved to see CCTray in Java released a bit earlier.

Finally a screenshot for those really interested.

On the down side — I’ve to remember all the keyboard shortcuts. This is hardly an option when there are a whole lot of keyboard shortcuts to remember, quite a lot keyboard shortcuts in most IDEs don’t really make much sense, and quite a few features do not even have keyboard shortcuts!

NO LONGER!

This Quick Assist (CTRL+3) feature in the latest version (3.3-M7) of eclipse makes available ALL the UI elements – views, menu entries, even refactorings all in one single place. What’s more it supports CamelCaseCompletion. This combination makes for some kick-ass development.

Keyboard Shortcuts — what’s that ?

Oh yeah, and there’s support for a brand new refactoring — Introduce Parameter Object

In certain cases, say for example when the build is taking longer than usual, and needs to be killed/stopped, the XmlLogger does not flush contents to disk.

It would be nice if there is some sort of a composite logger than can chain any logger along with the XmlLogger.

I just happened to write one sometime today. This is the source code for a CompositeLogger that logs to a default logger, and the XmlLogger. This needs the environment variable ANT_LOG_PREFIX to be set (there’s no better way I can think of)

In the end, this is great news for Eclipse which now gets to interact with a whole new set of users and developers.

Eclipse (OSGi) on clients… devices… servers… , what’s next?
…

OSGi is great on my desktop, laptop, servers, even mobile phones. But lotus notes based on OSGi ? I’m a die hard Eclipse fan and developer. But when it comes to usability of the software that I have to use everyday I’m a tough guy to convince.

For another potshot at this installer (for now) it is about 673 MB, is packaged as a .tar (Anyone at IBM lotus notes packaging team heard about something called as gzip/bzip2?) The documentation (which is about a total of 3MB) comes as a separate download. While it is a good idea to package the documentation separately I wonder if the installer comes with some documentation.

I just hope that I do not have to go through all these pains and musings and some more pains to install Lotus Notes 8. Especially after downloading something that is 673 MB.
