Problem initializing JMeter variables - Was "How can I add a JMeter property in code"
I tried this code earlier for setting JMeter variable (say, '${var}'
--------------
public void modifyTestElement(TestElement el)
{
el.setProperty(
new StringProperty("var","REPLACED"));
--------------
Since that didn't work, I tried manipulating the context (saw this type
of coding in RegexExtractor.java):
--------------
public void modifyTestElement(TestElement el)
{
JMeterVariables jmv = new JMeterVariables();
jmv.put("var", "REPLACED");
JMeterContext context =
JMeterContextService.getContext();
context.setVariables(jmv);
--------------
It didn't work either. "${var}" stays un-substituted.
If someone could help, that would be great - the Javadoc and the
extension documentation isn't descriptive enough.
With regards,
Sonam Chauhan

Re: Problem initializing JMeter variables - Was "How can I add a
JMeter property in code"
Posted by Jordi Salvat i Alabart <js...@atg.com>.
You're absolutely right: the developer documentation is absolutely
insufficient.
The change you want to do probably requires changes in the JMeter
engine. I created a "User Defined Variables" element to define variables
outside of the Test Plan and that's what I had to do. I'm attaching the
CVS message for my changes for your reference. If you use latest CVS
code, you may be able to subclass my component in some way...
Good luck,
Jordi.
