Class instantiation failure within groovy block of webtest
----------------------------------------------------------
Key: WT-503
URL: http://webtest-community.canoo.com/jira/browse/WT-503
Project: WebTest
Type: Bug
Versions: 2.6
Environment: OS: Various windows-based (ie. XP, 2000, etc)
Reporter: Chris Carman
Attachments: javahack.xml, t5.java
There appears to be a class instantiation bug of some kind when groovy code is
executed within a webtest.
In the attached webtest (javahack.xml) tests 1 - 4 work fine, but test 5 fails.
This is test 4:
<groovy description="groovy test 4">
import org.apache.log4j.Logger;
l = Logger.getLogger(Logger.class);
println("Groovy test 4 completed!");
</groovy>
And this is test 5 (which fails even though the "t5" class it instantiates
calls the same "getLogger" method as test 4):
<groovy description="groovy test 5">
test = new t5();
println("Groovy test 5 completed!");
</groovy>
t5.java contains only the following:
import org.apache.log4j.Logger;
public class t5
{
public Logger LOGGER;
public t5() {
LOGGER = Logger.getLogger(Logger.class);
}
}
Additionally, both test4 and test5 work fine when run through Groovy alone, so
this appears to be a problem with Webtest.
The following stack trace is generated:
