java - Stripes framework unit testing: MockServletContext giving NullPointerException -

-

edit: can ignore of have written below:

i getting null value of context when following in testng code:

 public void setupnontrivialobjects() {      testfixture.context = new mockservletcontext("test");      }

am supposed more make mockservletcontext object not null?

original: learning use stripes framework testng.

i following example here (but adapting own code): http://www.stripesframework.org/display/stripes/unit+testing under heading approach 2

i have test:

public class seedsearchactionbeantest { @test public void seedsearchtest() throws exception {     // setup servlet engine     mockservletcontext ctx = testfixture.getservletcontext();      mockroundtrip trip = new mockroundtrip(ctx, seedsearchactionbean.class);     trip.setparameter("input", "sdfs");     trip.execute();      seedsearchactionbean bean = trip.getactionbean(seedsearchactionbean.class);     assert.assertequals(bean.getinput(),"sdfs");     assert.assertequals(trip.getdestination(), "/results.jsp");     } }

this "testfixture" not sure is.

public class testfixture {  private static mockservletcontext context;  @beforesuite  public void setupnontrivialobjects() {      testfixture.context = new mockservletcontext("test");           // add stripes filter      map<string,string> filterparams = new hashmap<string,string>();      filterparams.put("actionresolver.packages", "net.sourceforge.stripes");      context.addfilter(stripesfilter.class, "stripesfilter", filterparams);      // add stripes dispatcher      context.setservlet(dispatcherservlet.class, "stripesdispatcher", null);  }   public static mockservletcontext getservletcontext() {      return testfixture.context;      } }

i error

failed: seedsearchtest java.lang.nullpointerexception @ net.sourceforge.stripes.mock.mockroundtrip.geturlbindingstub(mockroundtrip.java:384) @ net.sourceforge.stripes.mock.mockroundtrip.<init>(mockroundtrip.java:96) @ net.sourceforge.stripes.mock.mockroundtrip.<init>(mockroundtrip.java:82) @ sempedia.tests.action.seedsearchactionbeantest.seedsearchtest(seedsearchactionbeantest.java:17) @ sun.reflect.nativemethodaccessorimpl.invoke0(native method) @ sun.reflect.nativemethodaccessorimpl.invoke(nativemethodaccessorimpl.java:39) @ sun.reflect.delegatingmethodaccessorimpl.invoke(delegatingmethodaccessorimpl.java:25)

i guess line mockservletcontext ctx = testfixture.getservletcontext(); not working, wondering if there missing, particularly, there have in web.xml?

the mistake line:

 filterparams.put("actionresolver.packages", "net.sourceforge.stripes");`

this should (in case):

filterparams.put("actionresolver.packages", "action");

essentially setting package name actionbeans found. seems obvious once know it.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
