System Rules is a collection of JUnit rules for testing code which uses
java.lang.System
.
System Lambda is an alternative to System Rules that leverages the possibilities of Java 8. It is independent of the test framework. You can use it for example as a replacement for System Rules in JUnit Jupiter and TestNG.
System Rules is available from Maven Central.
