使用mock执行测试用例失败

Question

我正在尝试使用mokito框架执行测试用例，但遇到了一些错误。下面是我的代码:

public interface SaleforceSearchLeadService {
    public String buildSOSL(String email);
}
public class SalesforceLeadSearch1 implements SaleforceSearchLeadService{  
    public SalesforceLeadSearch1(){
    }
    private final static Logger LOGGER = LoggerFactory.getLogger(SalesforceLeadSearch1.class);
    public String buildSOSL(String email)
    {
        StringBuilder query = new StringBuilder();
        query.append("SELECT FirstName, LastName, Company, Status, Email, Age__c FROM LEAD ");
        query.append("WHERE Email = '"+email+"'"); 
        return query.toString();
    }
}
public class SalesforceLeadSearch1Test  {
  @Mock
  private SaleforceSearchLeadService service;
    @Test
    public void testBuildSOSL() {
       SalesforceLeadSearch1 test=new SalesforceLeadSearch1();
       StringBuilder query = new StringBuilder();
       String email="[e-mail]";
       query.append("SELECT FirstName, LastName, Company, Status, Email, Age__c FROM LEAD ");
       query.append("WHERE Email = '"+email+"'");
      // assertEquals("SELECT FirstName, LastName, Company, Status, Email, Age__c FROM LEAD WHERE Email = '[e-mail]'",service.buildSOSL(email));
        assertEquals("SELECT FirstName, LastName, Company, Status, Email, Age__c FROM LEAD WHERE Email = 'vivek.k@.com'",test.buildSOSL("[e-mail]"));
    }
}

下面是堆栈跟踪:

java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
    at com.ig.igwebcms.services.impl.SalesforceLeadSearch1.<clinit>(SalesforceLeadSearch1.java:40)
    at com.ig.igwebcms.services.test.SalesforceLeadSearch1Test.testBuildSOSL(SalesforceLeadSearch1Test.java:39)

我甚至尝试使用服务实例，这给了我NPE。

如果我从SalesforceLeadSearch1类中删除Logger，它通过了测试，不明白为什么?

谢谢

您的项目缺少一个SLF4j实现。如果使用Maven，请确保它包含在CLASSPATH中，或者在POM中定义。
