java - PowerMockito:使用字符串 [] 参数模拟静态方法时出现 InvalidUseOfMatchersException

Question

org.mockito.exceptions.misusing.InvalidUseOfMatchersException:在此处检测到错误的参数匹配器:

我在对以下静态方法执行 powermockito 时遇到了 org.mockito.exceptions.misusing.InvalidUseOfMatchersException 异常。

public class ShellCommandUtil {
    public static ArrayList executeShellCommand(String[] shellcmd) { 
        ArrayList output = new ArrayList(); 
         //removed the actual logic of sending shellcommand to the system   getting the result;
        return output;
    }
}

编写的TestMethod定义如下

@RunWith(PowerMockRunner.class)
 @PrepareForTest(ShellCommandUtil.class)
 public class ShellDataTest{
@Test
 public void testExecuteShellCommand() {
     ArrayList resultData = new ArrayList();
     resultData.add("data1");
     resultData.add("data2");
     PowerMockito.mockStatic(ShellCommandUtil.class);
     PowerMockito.when(ShellCommandUtil.executeShellCommand(Mockito.any(String [].class))).thenReturn(resultData);
    }
 }

你能帮忙看看这一行定义的错误吗

PowerMockito.when(ShellCommandUtil.executeShellCommand(Mockito.any(String[].class))).thenReturn(resultData);

在pom.xml中，我添加了以下依赖

<!-- https://mvnrepository.com/artifact/org.powermock/powermock-mockito-release-full -->
<dependency>
    <groupId>org.powermock</groupId>
    <artifactId>powermock-mockito-release-full</artifactId>
    <version>1.6.4</version>
    <type>pom</type>
</dependency>

请让我知道您对这个问题的看法。

谢谢，拉杰斯瓦里

根据PowerMockito类的Javadoc，你应该写

PowerMockito.when(ShellCommandUtil.class, "executeShellCommand", Mockito.any(String [].class)).thenReturn(resultData);
