that known issues. problem can't find working solution. code of test this:

package mh.scene.terrain;  import static org.easymock.easymock.createmock; import static org.junit.assert.assertequals; import static org.junit.assert.assertfalse; import static org.junit.assert.asserttrue;  import java.io.file;  import mh.cachedresources; import mh.scene.entity.player.entityplayerlocal;  import org.junit.test; import org.junit.runner.runwith; import org.powermock.api.easymock.powermock; import org.powermock.core.classloader.annotations.preparefortest; import org.powermock.modules.junit4.powermockrunner;  @suppresswarnings("javadoc") @runwith(powermockrunner.class) //@preparefortest(cachedresources.class) public class mapreadertestnew {     @test     public void testacceptvalidfilenames() {         // arrange         tmxmapreader reader = new tmxmapreader();          // assert         asserttrue(reader.accept(new file("example.tmx")));         asserttrue(reader.accept(new file("/tmp/example.tmx")));         asserttrue(reader.accept(new file("/tmp/example.tsx")));         asserttrue(reader.accept(new file("/tmp/example.tmx.gz")));         assertfalse(reader.accept(new file("/tmp/example.txt")));         assertfalse(reader.accept(new file("/tmp/example.xml")));         assertfalse(reader.accept(new file("/tmp/example.exe")));         assertfalse(reader.accept(new file("/tmp/example")));     }      @test     public void testreadingmapexample() throws exception {           entityplayerlocal pl = createmock(entityplayerlocal.class);         map map = new tmxmapreader().readmap("/sewers.tmx", null, pl);  //      powermock.mockstatic(cachedresources.class); //      powermock.replay(cachedresources.class);          assertequals(50, map.getheight());         assertequals(50, map.getwidth());         assertequals(1, map.gettilesetcount());         assertequals(3, map.getlayercount());         assertequals(1, map.getobjectsetcount());     } }

that extremely simple, , removing "powermock.mockstatic()" error present when add runwith

any idea?

the problem seems in part of code: 

file jar_file = (magichogwarts.class.getprotectiondomain().getcodesource().getlocation() == null ? null : new file(magichogwarts.class.getprotectiondomain().getcodesource().getlocation().getpath()));

that returns null. correct way handle paths testable powermock? particular error thrown when use statement "runwith"

you might need add entityplayerlocal.class @preparefortest(). createmock(entityplayerlocal.class) method causing issue guess. can check code written in once. better if can paste method in question.

c# - Validate object ID from GET to POST -

i have method allows user access comment have made on site. have post method lets them update comment. my normal solution send entire comment model through, let them update it, update on database when post back. involve sending commentid through in hiddenfor , can manipulated. how can verify commentid sent in get method same i'm getting in post , not able alter comment wish? how can verify commentid sent in method same i'm getting in post? basically have validate following things in post - user logged-in user. authenticated users post comments. commentid in post , should valid commentid , should present in database. userid associated logged-in user should same userid associated comment . comment should contain userid column, can check @ time of update. to make sure update happens comment has been sent in get - hold commentid in session , in post action compare commentid value in session .
