Hi all,
This kind of discussion should normally stay on devel mailing list, but I don't
know if there are many people registered.
As you may know, Raghu found a classloading issue in JWebUnit that prevents its
use for load testing tests. I think it's a major issue, but I don't know what
is the best wayto solve it, and I need some help.
First, the description of the problem:
We have a Java Interface (former IJWebUnitDialog, perhaps ITestingEngine in
future release), that each plugin should implement. Currently, we have only one
plugin : HtmlUnit, but I hope to add Selenium one for next release.
JWebUnit provide a way to specify plugin at runtime:
TestingEngineRegistry.addTestingEngine("myTestingEngine",
"com.mycompany.this.class.implements.IJWebUnitDialog.theClass");
tester.setTestingEngineKey("myTestingEngine");
beginAt("...");
To achieve this, I'm using Class.forName(). Unfortunately, this do not play
well with multiple threads. In fact, another famous OSS is suffering of this
problem: commons-logging. There are many articles about this problem,
especially:
http://www.qos.ch/logging/classloader.jsp
One solution could be to use the same solution as slf4j project. This solution
consists in linking statically with the implementation. The drawback is you
can't change plugin at runtime, and you can't have more than one plugin at the
same time in the classpath.
Perhaps could we also experiment integration with a lightweight container like
Spring to choose the implementation at runtime...
Any idea or comments?
