Using Java Request Sampler inside a ForEach controller in Jmeter - foreach

Question

I am Trying to use a Java request Sampler inside a ForEach Controller.
This is my custom Sampler
public class ClientSampler extends AbstractJavaSamplerClient {
String Name;
#Override
public Arguments getDefaultParameters() {
Arguments defaultParameters = new Arguments();
defaultParameters.addArgument("name", "Tarek");
return defaultParameters;
}
#Override
public void setupTest(JavaSamplerContext context) {
Name = context.getParameter("name");
}
#Override
public SampleResult runTest(JavaSamplerContext context) {
System.out.println(Name);
}
}
in Jmeter I create user defined variables with 5 variables:
And a ForEach Controller:
then added the java request as a child to ForEach controller:
the Test plan is the following:
when I start the test the output is:
first
first
first
first
first
expected:
first
second
third
fourth
fifth
even if I set the start and end indexes in the ForEach controller the result is the same.
using an http sampler inside the ForEach controller works great, but when using a Java requests the result is not as expected.
Can anyone explain why I am getting this output?

Answer 1

I solved it.
The problem is because I misunderstood how it works:
Jmeter calls SetupTest(JavaSamplerContext context) once before the Test starts and calls runTest(JavaSamplerContext context) in each loop (I though it calls SetupTest also at the beginning of each loop).
so I just added
Name = context.getParameter("name");
inside runTest and now the result is exactly how it should be.
#Override
public SampleResult runTest(JavaSamplerContext context) {
Name = context.getParameter("name");
System.out.println(Name);
}
