在Android中嘲弄

Question

我試圖在Android應用程序中測試KeyguardManager類的isKeyguardSecure()方法。

我試過了，並且使用EasyMock,Mockito和PowerMock創建了一個模擬KeyguardManager對象。以下是我的嘗試和收到的錯誤消息。

---

EasyMock的

KeyguardManager keyguardManagerMock = EasyMock.createMock(KeyguardManager.class);

錯誤消息：java.lang.IllegalArgumentException: android.app.KeyguardManager is not an interface

---

和的Mockito PowerMock

個KeyguardManager mockedKeyguardManager = Mockito.mock(KeyguardManager.class); KeyguardManager mockedKeyguardManager = PowerMockito.mock(KeyguardManager.class);

錯誤消息：java.lang.VerifyError: mockit/internal/startup/Startup java.lang.VerifyError: org/mockito/cglib/core/ReflectUtils

One explanation for this指出問題的根源是與Dalvik虛擬機，其Android設備運行。任何人都可以驗證此？是否有可能使用可用於測試Android應用程序的任何可用模擬庫來模擬KeyguardManager類？

謝謝！

Answer 1

在EasyMock中使用PowerMock。

依賴關係：

testCompile 'junit:junit:4.12' 
testCompile 'org.easymock:easymock:3.3.1' 
testCompile 'org.powermock:powermock-core:1.6.2' 
testCompile 'org.powermock:powermock-api-easymock:1.6.2' 
testCompile 'org.powermock:powermock-module-junit4:1.6.2' 

示例代碼：

package com.example.user.exampleapp; 

import android.app.KeyguardManager; 

import org.easymock.EasyMock; 
import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.powermock.api.easymock.PowerMock; 
import org.powermock.core.classloader.annotations.PrepareForTest; 
import org.powermock.modules.junit4.PowerMockRunner; 

@RunWith(PowerMockRunner.class) 
@PrepareForTest(KeyguardManager.class) 
public class KeyguardTest { 

    @Test 
    public void testKeyguard() { 
     KeyguardManager keyguardMock = PowerMock.createMock(KeyguardManager.class); 
     EasyMock.expect(keyguardMock.isKeyguardSecure()).andReturn(false); 
     PowerMock.replayAll(); 
     System.out.println("is locked " + keyguardMock.isKeyguardSecure()); 
     PowerMock.verifyAll(); 
    } 
} 

輸出：

is locked false

你EasyMock的版本太舊。 PowerMock不是必需的。使用EasyMock 3.4，我做了下面的工作，它工作完美：

public static void main(String[] args) { 
    KeyguardManager manager = createMock(KeyguardManager.class); 
    expect(manager.isKeyguardSecure()).andReturn(true); 
    replay(manager); 
    assertTrue(manager.isKeyguardSecure()); 
    verify(manager); 
}
