i creating new @rule use case looks
public class activedirectoryconfigurationrule extends externalresource { @rule public temporaryfolder temporaryfolder = new temporaryfolder(); public file addactivedirectoryconfigurationtofile(activedirectoryconfiguration configuration) throws ioexception { file file = temporaryfolder.newfile(); objectmapper.writevalue(file, configuration); return file; } private objectmapper registerjdk8moduleandgetobjectmapper() { objectmapper objectmapper = new objectmapper(); objectmapper.registermodule(new jdk8module()); return objectmapper; } } in test use
public class activedirectoryconfigurationstoretest { @rule public activedirectoryconfigurationrule configurationrule = new activedirectoryconfigurationrule(); @test public void getwhenconfigurationexists() throws exception { activedirectoryconfiguration activedirectoryconfiguration = //....; file configurationtofile = configurationrule.addactivedirectoryconfigurationtofile(activedirectoryconfiguration); activedirectoryconfigurationstore configurationstore = new activedirectoryconfigurationstore(configurationtofile); optional<activedirectoryconfiguration> maybeconfiguration = configurationstore.getconfiguration(); asserttrue(maybeconfiguration.ispresent()); } } when run test, error

is issue? , how resolve it?
yes, don't think there's built in junit let "nest" @rule objects you're doing.
i think obvious options be:
- in custom @rule, call various methods on child @rule @ appropriate times. (essentially, pretend junit library, using @rule per interface.) haven't dug details see how complex be.
- have @rule extend
temporaryfolderratherexternalresource, making sure callsuper()in of methods you're overriding. lets "everythingtemporaryfolder, some", perhaps isn't perfect oo-theory (as it's not type-of temporaryfolder) should work way you're looking for. i've used approach when setting particular folder needed set particular environment tests, , worked well. - have custom @rule take in constructor parameter
temporaryfolderreference, save in field , use needed. requires users of @rule include both @rule objects, perhaps makes clear test require both temporary folder work in particular custom setup.
