How can I set up testing environment for plugin depending on JavaScriptLang?

Hi, 

I'm writing tests for the my plugin which depends on JavaScriptLang. I can run/debug on IDEA ultimate very well, but finding that may be I can't run tests code extedings `LightCodeInsightFixtureTestCase`, since the result shows: "java.lang.NoClassDefFoundError: org/apache/http/conn/ssl/SSLConnectionSocketFactory". 

So I have to set up IDEA community and add JavaScriptLang.jar and CSS.jar to the class path of it. Am I right?

But after I have done it, there is another error appear, it says: 

java.lang.RuntimeException: com/intellij/webcore/libraries/ScriptingLibraryManager

My test file is quite simple:

package com.netease.NEJ.core.define;

import com.intellij.testFramework.fixtures.LightCodeInsightFixtureTestCase;


/**

 */
public class DefinePathSettingTest extends LightCodeInsightFixtureTestCase{
    public void testPathSetting() {
        assertEquals("true", "true");
    }
}


So could any one tell me how to fix it?
