MethodOrderer.Random (JUnit 5.5.2 API)

java.lang.Object
- 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 at INFO level. In addition, a custom seed (potentially the default seed from the previous test plan execution) may be specified via the junit.jupiter.execution.order.random.seed configuration parameter which can be supplied via the Launcher API, build tools (e.g., Gradle and Maven), a JVM system property, or the JUnit Platform configuration file (i.e., a file named junit-platform.properties in the root of the class path). Consult the User Guide for further information.
