How to add Java system property at runtime with JUnit Test Execution

Question

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

• systemProp.foo = line definition in gradle.properties file
• pass -Dfoo = bar on the command line
• pass -PsystemProp.foo = bar on the command line

I do not see the additional properties from the gradle properties, although I'm not sure what I should. But more importantly, I dropped System.properties in the static initializer, but the property is not there. I need to pass System properties to current tests to tell them which environment they are working in (local, Jenkins, etc.).

Answer 1

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

test {systemProperties = System.properties}

Answer 2

You can also define individual properties as follows:

test { systemProperty "file", "test.story" }
