無法使用JMockit模擬靜態調用

我無法模擬靜態調用。我不知道我做錯了什麼。無法使用JMockit模擬靜態調用

我剝了下來源代碼：

import javax.servlet.http.HttpServletRequest; 

import org.apache.struts2.ServletActionContext; 

public class OptionsBusinessEventFormatter { 

    void process() { 
    System.out.println("Testing testing "); 
    HttpServletRequest request = ServletActionContext.getRequest(); 
    System.out.println("request = " + request); 
    System.out.println(request.getParameter("returnedURI")); 
    } 
}

我的單元測試

@RunWith(JUnit4.class) 
public class OptionsBusinessEventFormatterTest { 

    private OptionsBusinessEventFormatter optionsBusinessEventFormatter; 

    @Before 
    public void setUp() throws Exception { 
    this.optionsBusinessEventFormatter = new OptionsBusinessEventFormatter(); 
    } 

    @Test 
    public void process_HappyPath() { 
     final MockHttpServletRequest request = new MockHttpServletRequest(); 
     Map<String, String> map = new HashMap<>(); 
     request.setParameters(map); 
     new Expectations() { 
      @Mocked ServletActionContext servletContext; 
      { 
       ServletActionContext.getRequest(); 
       result = request; 
      } 
     }; 
     this.optionsBusinessEventFormatter.process(); 
    } 
}

我碰到下面的錯誤。

下面

public class MockServletActionContext extends MockUp<ServletActionContext> { 

     private final MockHttpServletRequest request; 

     public MockServletActionContext(MockHttpServletRequest request) { 
      this.request = request; 
     } 

     @Mock void $init() {} 

     @Mock 
     public HttpServletRequest getRequest() { 
      return this.request; 
     } 
    }

給出我得到同樣的錯誤，我即使使用樣機實例嘗試。

如異常消息所示，執行測試的JRE缺少JMockit需要的Attach API本機庫。可能你正在使用一個普通的JRE，它確實不包含'attach.dll'。要解決此問題，請將IDE配置爲從完整的JDK安裝（即，' \ jre'）使用JRE。 –

我已經安裝了Oracle Java 7 JDK並設置了JAVA_HOME並將$ JAVA_HOME/bin附加到現有的$ PATH變量中。 – Kartik

JMockit不使用像JAVA_HOME，PATH等環境變量。可能甚至連您的Java IDE（假設正在使用）都可以使用它們。如果通過IDE執行測試，則需要將其配置爲使用所需的JDK/JRE。 –

我不得不把下面的東西得到執行從Eclipse的

Debug > Create new Launch Config> Select a Test Case > Arguments > VM Arguments > Path to jMockit Jar.

運行與Maven

<build> 
    <plugins> 
     <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-surefire-plugin</artifactId> 
      <version>2.5</version> 
      <dependencies> 
       <dependency> 
        <groupId>org.apache.maven.surefire</groupId> 
        <artifactId>surefire-junit47</artifactId> 
        <version>2.17</version> 
       </dependency> 
      </dependencies> 
      <configuration> 
       <argLine> 
        -javaagent:"${settings.localRepository}"/com/googlecode/jmockit/jmockit/${jmockit.version}/jmockit-${jmockit.version}.jar 
       </argLine> 
       <redirectTestOutputToFile>true</redirectTestOutputToFile> 
      </configuration> 
     </plugin> 
    </plugins> 
</build>

這爲我工作。
