i'm new @ junit , use inteliji idea.

import org.junit.test; import org.junit.ignore; import org.junit.runner.runwith; import org.junit.runners.junit4; import java.util.date; import static org.junit.assert.*; public class testquote {     @test     public void testquote() {         date date = new date(system.currenttimemillis());         quote quote=new quote("a",date,200.0,300.0,100.0,107.0,1.0);         assertnull("object null",quote);         assertequals("symbol ok",quote.getsymbol(),"a");         assertequals("date ok",quote.getdate(),system.currenttimemillis());         assertequals("open price ok",quote.getopenprice(),200.0);         assertequals("high price ok",quote.gethighprice(),300.0);         assertequals("low price ok",quote.getlowprice(),100.0);         assertequals("close price ok",quote.getcloseprice(),107.0);     } }
