[ddsteps-user] about the null pointer exception of ddsteps-1.1

[许刚强 <urb...@16...>]

 
 Hi everyone:
 
 I downloaded ddsteps 1.1 from sourceforge and run one test case with the following exceptions: 
java.lang.NullPointerException

I downloaded the source code for ddsteps 1.1 and ehcache-1.2.3 and found the following errors: 
in org.ddsteps.dataset.CachingDataSetLoader line 164: 
try { 
Cache backingCache = CacheManager.getInstance().getCache(CACHE_NAME); 
cache = new SelfPopulatingCache(backingCache, new DataSetFactory()); 
} catch (CacheException e) { 
throw new DDStepsException("Could not create cache for DataSet:s.", e); 
} 
the backingCache is null. 

Following is my test case: 
public class DdStringComparatorTest extends DdTestCase { 

private String one; 

private String two; 

private boolean result; 

private StringComparator comp = new StringComparator(); 

/** 
* testing method for compare 
* 
*/ 
public void testCompare() { 
System.out.println("test"); 
assertEquals("one=" + one + ",two=" + two + ",result=" + result, 
result, comp.compares(one, two)); 
System.out.println("after test"); 
} 

/* 
* (non-Javadoc) 
* 
* @see org.ddsteps.DDStepsTestCase#createDataLoader() 
*/ 
public DataLoader createDataLoader() { 
return CachingExcelDataLoader.getInstance(); 
} 

/** 
* @param one 
* the one to set 
*/ 
public void setOne(String one) { 
this.one = one; 
} 

/** 
* @param result 
* the result to set 
*/ 
public void setResult(boolean result) { 
this.result = result; 
} 

/** 
* @param two 
* the two to set 
*/ 
public void setTwo(String two) { 
this.two = two; 
} 

} 

 
Anyone have any idea?
Thanks in advance.
