Class MethodOrderer.Random

- org.junit.jupiter.api.MethodOrderer.Random
-
- All Implemented Interfaces:
MethodOrderer
- Enclosing interface:
- MethodOrderer
public static class MethodOrderer.Random extends Object implements MethodOrderer
MethodOrderer
that orders methods pseudo-randomly.Custom Seed
By default, the random seed used for ordering methods is the value returned by
System.nanoTime()
during static initialization of this class. In order to support repeatable builds, the value of the default random seed is logged atCONFIG
level. In addition, a custom seed (potentially the default seed from the previous test plan execution) may be specified via thejunit.jupiter.execution.order.random.seed
configuration parameter which can be supplied via theLauncher
API, build tools (e.g., Gradle and Maven), a JVM system property, or the JUnit Platform configuration file (i.e., a file namedjunit-platform.properties
in the root of the class path). Consult the User Guide for further information.- See Also:
