对于静态方法，带有PowerMockito的测试失败

Question

我正在尝试使用testng和powermockito将单位测试添加到旧的报告生成代码中。

import static org.testng.AssertJUnit.assertTrue;
import static org.powermock.api.support.membermodification.MemberModifier.stub;
import org.testng.annotations.Test;
import org.mockito.Matchers;
import org.mockito.Mockito;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
@PrepareForTest(ConfigReader.class)
public class defTest{
    @Test
    public void testGetPartsSuccessful() throws Exception {
        TrendsReportData reportGenerator = new TrendsReportData();
        TreeMap<Calendar, String> t = new TreeMap<Calendar, String>();
        Calendar c = Calendar.getInstance();
        String b = "234";
        t.put(c, b);
        Properties properties = new Properties();
       properties.load(Thread.currentThread().getContextClassLoader().getResourceAsStream("MetricTest.properties"));
        MetricDAO dao = Mockito.mock(MetricDAO.class);
        Mockito.when(
                          dao.getMetricData(Matchers.anyString(), Matchers.anyString(),
                                          Matchers.anyString(), Matchers.any(Calendar.class),
                                          Matchers.any(Calendar.class))).thenReturn(t);
        //stub (PowerMockito.method(ConfigReader.class, "readFile")).toReturn(properties);//line 36
        PowerMockito.mockStatic(ConfigReader.class); //line 37
        Mockito.when(ConfigReader.readFile(Matchers.anyString())).thenReturn(properties);//line 38
        reportGenerator.setMetricDao(dao);
        reportGenerator.prepareMonthStats();
        //assert file here
    }
}

此代码正在产生以下输出：

[testng] org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 
[testng] Misplaced argument matcher detected here:
[testng] -> at .....defTest.testGetPartsSuccessful(defTest.java:38)

如果我评论第37和38行并使用第36行，则可以正常工作，但不会产生所需的输出，即它不是模拟configReader的静态方法，但它是模拟metricdao的非静态方法。

我研究了其他类似问题提供的答案，但它们都没有起作用。请帮助。

Answer 1

根据PowerMock文档，您的测试类应从PowerMockTestCase延长。还提到了将此方法添加到您的测试类中：

 @ObjectFactory
 public IObjectFactory getObjectFactory() {
     return new org.powermock.modules.testng.PowerMockObjectFactory();
 }

但是这些更改都不适合我：（

因此，我切换到Jmockit，它像魅力一样工作。用Mockito编写的模拟与Jmockit的部分模拟静态方法一起工作。
