Java 实现JUnit4（Mockito）时出错

这是我正在尝试实现的junit

请帮忙

下面是CreateHashMapAPI

publicstatichashmap createHashMap（字符串a\u NameValStr，字符串a\u Delim）
{
HashMap w_KeyVal=新的HashMap（）；
if（LOGGER.isInfoEnabled（））LOGGER.info（“CollectionUtil:createHashMap:Hashing字符串：”+a_NameValStr）；
如果（a_namevaltr==null）返回w_KeyVal；
StringTokenizer w_StrTkn=新的StringTokenizer（a_NameValStr，a_Delim）；
如果（w_StrTkn.countTokens（）==0 | |（w_StrTkn.countTokens（）%2）！=0）
{
LOGGER.warn（“CollectionUtil:createHashMap:要哈希的令牌数无效：“+a_NameValStr+”：“+w_StrTkn.countTokens（））；
返回w_KeyVal；
}
而（w_StrTkn.hasMoreTokens（））w_KeyVal.put（w_StrTkn.nextToken（），w_StrTkn.nextToken（））；
返回w_KeyVal；
}

“我想模拟createHashMap（）方法，它是静态方法。”您不能将其更改为非静态方法的确切原因是什么？嗨，jobin，我在问题中添加了createHashMap。您不能用Mockito模拟静态方法。考虑将它改为非静态方法，那么模拟静态方法还有什么选择？

import static org.mockito.Mockito.when;

import java.util.HashMap;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.runners.MockitoJUnitRunner;


@RunWith(MockitoJUnitRunner.class)
public class Power_Test {
    @InjectMocks
    ReportUtil w_res = new ReportUtil();

   CollectionUtil mock = org.mockito.Mockito.mock(CollectionUtil.class);

    @Test
    public void test_removeHashedSettings() throws Exception {

        HashMap<String, String> w_abc = new HashMap<String, String>();
        w_abc.put("abc", "89");

        when(mock.createHashMap("abc:89",":")).thenReturn(w_abc);
        Assert.assertEquals(ReportUtil.removeHashedSettings("1", "abc:89", ":"),"abc:89:",0);
    }
}

 org.mockito.exceptions.misusing.MissingMethodInvocationException: 
  when() requires an argument which has to be 'a method call on a mock'.
  For example:
  when(mock.getArticles()).thenReturn(articles);
  Also, this error might show up because:
  1. you stub either of: final/private/equals()/hashCode() methods.
  Those methods cannot be stubbed/verified.
  Mocking methods declared on non-public parent classes is not supported.
 2. inside when() you don't call method on mock but on some other object.
