JMeter - JUnit Request execute all methods - junit

Question

In JMeter JUnit Request I must choose Test method to define component:
Test method: The method to test. Required: Yes
How can I execute all methods in class? Isn't a way to define less than X JUnit Requests per method? it seems excessive, is there other way as using Java request?

Answer 1

This is by design, the purpose of JUnit Request sampler is to measure execution time of a single method.
If you are looking for a way to execute all methods in a given class and measure their cumulative execution time there are at least 2 ways:
Create as many JUnit Request samplers as many methods you have in your test and put them all under Transaction Controller
Use JSR223 Sampler and develop custom code to run your JUnit methods:
Using JUnit Computer class like:
import org.junit.runner.Computer
import org.junit.runner.JUnitCore
def computer = new Computer()
def jUnitCore = new JUnitCore()
jUnitCore.run(computer, Foo.class)
Using Java Reflection Api like:
import org.apache.commons.lang3.reflect.MethodUtils
import org.junit.Test
import java.lang.reflect.Method
Class junitClass = Class.forName('Foo')
Object t = junitClass.newInstance()
List<Method> testMethods = MethodUtils.getMethodsListWithAnnotation(junitClass, Test, false, true)
testMethods.each { method ->
method.invoke(t, null)
}
Replace Foo with the fully qualified name of your JUnit class in both examples in order to get it to work.
