How can I pass Java SystemProperties to a Gradle JunitTest

I got a JUnit test that relies upon a Java SystemProperty (more precisely the library used in it relies on it). I want to start the JUnit test from IntelliJ. Therefore I edited the run configuration and added VM options like "-DpropertyName=value". IntelliJ then starts gradle with something like this:

gradle cleanTest test --tests com.example.Test -DpropertyName=value

When I check from my Test with System.getProperty() / getProperties() the property was not passed and thus is null.

How can i pass the properties to the JunitTest?

As it turns out, IntelliJ can only pass those JVM options to the JVM gradle runs in and gradle will not pass those to the tests. To specify a property for the JVM that will run the tests, either edit the build.gradle file and add:

test {
  systemProperty 'propertyName', 'value'
}

or, instead, add

test.jvmArgs System.getProperty("test.jvmArgs").split(" ")

to the build.gradle file and modify your run configuration VM options to be something like

-Dtest.jvmArgs="-DpropertyName=value -Dprop2=value2"
