我在我的 class 中使用 private static final LOGGER 字段,我希望 LOGGER.isInfoEnabled() 方法返回 false . 如何使用mockito或jMockit模拟静态final字段
我的 class 是:
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class Class1 {
private static final Logger LOGGER = LoggerFactory.getLogger(Class1.class);
public boolean demoMethod() {
System.out.println("Demo started");
if (LOGGER.isInfoEnabled()) {
System.out.println("@@@@@@@@@@@@@@ ------- info is enabled");
} else {
System.out.println("info is disabled");
}
return LOGGER.isInfoEnabled();
}
}
它的junit是:
import mockit.Mocked;
import mockit.NonStrictExpectations;
import org.mockito.InjectMocks;
import org.mockito.MockitoAnnotations;
import org.slf4j.Logger;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;
import static org.testng.Assert.*;
import com.source.Class1;
public class MyTest {
@InjectMocks
Class1 cls1;
@BeforeMethod
public void initMocks() {
MockitoAnnotations.initMocks(this);
}
@Test
public void test(@Mocked final Logger LOGGER) {
new NonStrictExpectations() {
{
LOGGER.isInfoEnabled();
result = false;
}
};
assertFalse(cls1.demoMethod());
}
}
当我运行它时,结果是:

我是jmockit的新手,我希望我的上面的junit案例能够成功运行 . 我必须使用JMockit或mockito,不能使用Powermockito . 请帮忙 .

一种方法是使用反射从字段中删除
final
修饰符,然后用Mocked一个替换LOGGER
字段我认为mockito或jMockit不能模拟静态最终类,因为他们试图在单元测试时覆盖方法 . 但是,powerMockito可以使用Reflection并模拟静态最终类/方法 .
在参数中将“@Mocked Logger”更改为“@Capturing Logger”使其工作 .
