Somewhat ironically, test() appears to lack any Javadoc [1] because it was added to more closely emulate java.util.function.Predicate [2] and use of the Guava Predicate is discouraged by its authors anyway [3]. Since closure-compiler is hopelessly old, I think we should reevaluate where we are with respect to the necessary build-dependencies to update to a modern version of closure-compiler. Cheers, tony [1] https://www.javadoc.io/doc/com.google.guava/guava/29.0-jre/src-html/com/google/common/base/Predicate.html#line.77 [2] https://cr.openjdk.java.net/~iris/se/11/latestSpec/api/java.base/java/util/function/Predicate.html#test(T) [3] https://github.com/google/guava/wiki/FunctionalExplained#caveats
