How can I add a Java system property during JUnit Test Execution

Question

I need to define a system property for my JUnit tests. I've tried various steps to pass the name/value pair into gradle. (I've tried Milestone-3 and 4). None of these approaches worked:

• defining a systemProp.foo=bar in the gradle.properties file
• passing -Dfoo=bar at the command line
• passing -PsystemProp.foo=bar on the command line

I don't see the additional properties from "gradle properties" though I'm not sure I should. But more importantly, I dumped the System.properties in a static initializer and the property is not there. I need to pass System properties to the running tests to tell them what environment (local, Jenkins, etc) they are running in.

Sorry to answer my own question. Just stumbled upon the solution here:

test { systemProperties = System.properties }
