java - Testing a Spring WebListener -


i have class annotated @weblistener, extending servletcontextlistener class i'm testing relies on having executed. when test manually (i.e. running in tomcat) works, within junit test @weblistener class never executed. i'm assuming need add configuration execute, i'm not sure what. or need run manually in the test?

edit: here's basics of class

@weblistener public class mylistener implements servletcontextlistener {    @override   public void contextinitialized(servletcontextevent event) {     // retrieve spring application context     servletcontext servletcontext = event.getservletcontext();     springcontext = webapplicationcontextutils.getwebapplicationcontext(servletcontext);     ...   }   ... }

i've added test class:

@before public void mockinit() {     mockservletcontext mockcontext = new mockservletcontext();     new mylistener().contextinitialized(new servletcontextevent(mockcontext)); }

but springcontext variable in contextinitialized null.

assuming using mockmvc tests, can register filter with

mockmvcbuilders.webappcontextsetup(webappcontext).addfilter(yourfilter, urlpatterns);

ruby - How do I merge two hashes into a hash of arrays? -

http://codepad.org/wmyzqlis i'd merge these 2 arrays: a = { :a => 'a', :b => 'b', :d => 'd' } b = { :a => '1', :b => 'b', :c => 'c' } into hash looks this: {:a => ["a", "1"], :b => ["b", "b"], :c => [nil, "c"], :d => ["d", nil] } this doesn't work: p a.merge(b) { |k, v1, v2| [v1, v2] } # {:c=>"c", :a=>["a", "1"], :b=>["b", "b"], :d=>"d"} it's because hash#merge call block duplicate keys. a = { :a => 'a', :b => 'b', :d => 'd' } b = { :a => '1', :b => 'b', :c => 'c' } hash[(a.keys|b.keys).map { |key| [key, [a.fetch(key, nil), b.fetch(key, nil)]] }] # => {:a=>["a", "1"], :b=>["b", "b"], :d=>["d", nil], :c=>...
