Issue running test for RuleUnitDefinition in drools version 8.29.0.Final

Looking at test defined here:

public void testHelloWorld()

{ HelloWorldUnit unit = new HelloWorldUnit(); unit.getStrings().add("Hello World"); assertThat(unit.fire()).isEqualTo(2); assertThat(unit.getResults()).containsExactlyInAnyOrder("it worked!", "it also worked with HELLO WORLD"); unit.getResults().clear(); unit.getInts().add(11); assertThat(unit.fire()).isEqualTo(1); assertThat(unit.getResults()).containsExactly("String 'Hello World' is 11 characters long"); }

Build, Deploy, Utilize and Run :: Drools Documentation

 

This test does not compile:

unit.fire() <-- does not compile. if you can update this documentation to run the test, it will be great.
