Question

我在Eclipse（霓虹灯）中创建的Android测试项目中使用PowerMock。当我运行基本测试用例时，我在调用PowerMockito.spy()时收到 ExceptionInInitializationError 。

以下是报告的堆栈跟踪：

我的AndroidTestCase类：

package com.fuelpowered.lib.propeller.test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import android.test.AndroidTestCase;

@RunWith(PowerMockRunner.class)
@PrepareForTest({
    MyStaticClass.class
})
public class JPTestCase extends AndroidTestCase {

    @Test
    public void testJP() {
        PowerMockito.spy(MyStaticClass.class);
        assertTrue(true);
    }

}

正在监视的MyStaticClass.java类：

package com.fuelpowered.lib.propeller.test;

public class MyStaticClass {

    public static String foo() {
        return bar();
    }

    public static String bar() {
        return "bar";
    }

}

的AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.fuelpowered.lib.propeller.test"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="23" />

    <instrumentation
        android:name="android.test.InstrumentationTestRunner"
        android:targetPackage="com.fuelpowered.lib.propeller.test" />

    <application
        android:allowBackup="false"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <uses-library android:name="android.test.runner" />
    </application>

</manifest>

最后我在项目libs文件夹中包含的.jar库（在构建路径中）：

CGLIB的节点p-2.2.2.jar
dexmaker-1.4.jar
dexmaker-的Mockito-1.4.jar
了Javassist-3.19.0-GA.jar
的junit-4.12.jar
的Mockito-全1.10.19.jar
powermock-的Mockito-1.6.2-full.jar

除了dexmaker .jar库之外，所有其他库.jars都是从{{3}下载的 powermock-mockito-junit-1.6.2.zip 存档中获取的。 }。 dexmaker .jar库是从PowerMock GitHub project获得的。

为了让库彼此很好地编译，我必须修改并重新打包 mockito-all-1.10.19.jar 和 powermock-mockito-1.6.2- full.jar 库，因为它们与其他.jar库存在以下冲突：

./ LICENSE

./ NOTICE

mockito-all-1.10中的 ./ asm-license.txt 文件.19.jar

cglib-nodep-2.2.2.jar

./ mockito-extensions / org.mockito.plugins.MockMaker file powermock-mockito-1.6.1-full.jar 与存在的文件冲突 dexmaker-mockito-1.4.jar 中的名称相同，因此该文件已从PowerMock .jar库中删除。

此外， powermock-mockito-junit-1.6.2.zip 存档中包含的整个 objenesis-2.1.jar 库存在冲突，因为其内容已经包含在 mockito-all-1.10.19.jar 库中，所以我没有在测试项目中包含该库。

在模拟器（Nexus 5，Google API，API 21）和设备（Nexus 5，Android 5.1.1）上尝试了测试用例。

这几乎描述了所有项目设置和来源。我已经尝试在互联网上挖掘一段时间，但我仍然不知道我的设置中有什么错误或遗漏，所以任何帮助都会非常感激。提前谢谢！

您收到此错误是因为您必须将实例传递给PowerMockito.spy方法。它应该是这样的：

PowerMockito.spy(new MyStaticClass());

调用PowerMockito.spy（）
