Question

我有以下代码，我正在使用Mockito编写单元测试：

      while (results.hasMore()) {
            found = true;
            SearchResult searchResult = (SearchResult) results.next();
            Attributes attributes = searchResult.getAttributes();
            Attribute attr = attributes.get(LdapAttribute.CUSTOMER_GUID.getValue());
            setAttribute(attr);
            if (getAttribute() != null && cust.getCstCustGuid() == null) 
                cust.setCstCustGuid((String) attr.get());
      }

单元测试存根代码：

    Mockito.doReturn(mockCustomer).when(ldap).getLDAPCustomer();
    Mockito.doReturn(mockCtx).when(ldap).getInitialDirContext();
    Mockito.doNothing().when(ldap).setAttribute(Mockito.any(Attribute.class));
    Mockito.doReturn(mockAttribute).when(ldap).getAttribute();
    Mockito.doReturn(mockSearchControls).when(ldap).getSearchControls();
    Mockito.doNothing().when(mockSearchControls).setSearchScope(Mockito.anyInt());
    Mockito.when(mockCtx.search(Mockito.anyString(), Mockito.anyString(), Mockito.any(SearchControls.class))).thenReturn(mockResults);
    Mockito.when(mockResults.hasMore()).thenReturn(true).thenReturn(false);
    Mockito.when(mockResults.next()).thenReturn(mockSearchResults);
    Mockito.when(mockSearchResults.getAttributes()).thenReturn(mockAttributes);
    Mockito.when(mockAttributes.get(Mockito.anyString())).thenReturn(mockAttribute);
    Mockito.when(mockAttribute.get()).thenReturn(Mockito.anyObject());

    Mockito.when(mockCustomer.getCstCustGuid()).thenReturn(Mockito.anyString());
    Mockito.doNothing().when(mockCustomer).setCstCustGuid(Mockito.anyString());

我在这一行得到InvalidUseOfMatchers例外：

 Mockito.when(mockCustomer.getCstCustGuid()).thenReturn(Mockito.anyString());

请帮忙。

您无法在Mockito.anyString()内使用thenReturn()。您只能在使用Mockito.when()或Mockito.verify()时使用它。示例：Mockito.when(mockCustomer.getSomething(Mockito.anyString())).thenReturn(something);

对于您的问题，您应该用

替换行Mockito.when(mockCustomer.getCstCustGuid()).thenReturn(Mockito.anyString());

<强> Mockito.when(mockCustomer.getCstCustGuid()).thenReturn(""); 或

<强> Mockito.when(mockCustomer.getCstCustGuid()).thenReturn(Mockito.mock(String.class));

Mockito无效使用Matchers异常
