The default settings can be scaled via the cpuThreads property (i.e. -PcpuThreads=8). The default value is 8.

Special JVM argument accessors:
getAllocationAgentJVMArg()- Find location of-javaagent:[..]java-allocation-instrumenter[..].jargetSCSDefaultJVMArgs()- Default settings for SCS
The plugin will do a few other things too:
...
$ gradle test -Pcategory=fast // run fast tests| Code Block |
|---|
import org.junit.jupiter.api.Tag;
import org.junit.jupiter.api.Test;
@Test
public void fastTest() { ... } // runs in fast category
@Tag("allocation")
@Test
public void allocationTest() { ... } // runs in allocation category |

Running tests locally in your IDE
It is possible to run tests in parallel in your IDE, just pass these VM arguments:
