如果任何模块中存在模拟实例，则在创建 RoboGuice 注入器期间进程会崩溃

我在单元测试中使用 RoboGuice 和 AndroidMock 框架时遇到问题。我创建了一个简单的项目来展示我的问题。这里我创建了一个模拟实例并将其注册到 RoboGuice 中。但进程在“setUp()”和“test01()”方法之间崩溃。正如我猜测的那样，实际上，如果任何模块内部有模拟实例，则在创建注入器时进程会崩溃。

如果我用实现该接口的类的实例替换模拟实例，那么一切都会正常工作。

有人知道如何解决这个问题吗？

这是我的测试代码：

public class testInjectMock extends RoboUnitTestCase<MyApplication> {
    protected void setUp() throws Exception {
        InterfaceToMock instance = AndroidMock.createNiceMock(InterfaceToMock.class);           AndroidMock.expect(instance.SimpleMethod()).andStubReturn("Hello!");            
        MyModule myMockModule = new MyModule();
        myMockModule.setMockedInstance(instance);//Comment this string to get into the test01() method          
        MyApplication.setMyModule(myMockModule);
        super.setUp();
    }
    public void test01() {
        //It never comes here
    }
}

模块源代码：

public class MyModule extends AbstractAndroidModule {
        protected InterfaceToMock mockedInstance;
        public void setMockedInstance(InterfaceToMock mockedInstance) {
            this.mockedInstance = mockedInstance;
        }
        @Override
        protected void configure() {
            if(mockedInstance != null)
                bind(InterfaceToMock.class).toInstance(mockedInstance);
        }
    }

I have a problem with using RoboGuice and AndroidMock frameworks in unit testing.
I've created a simple project to show my problem. Here I create a mocked instance and register it in the RoboGuice.
But the process crashes between the "setUp()" and "test01()" methods.
As I guess, actually the process crashes when the Injector is created, if any module has a mocked instance inside.

If I replace the mocked instance with an instance of a class that implements the interface then everything works fine.

Does anybody know how to fix this problem?

Here is my test code:

public class testInjectMock extends RoboUnitTestCase<MyApplication> {
    protected void setUp() throws Exception {
        InterfaceToMock instance = AndroidMock.createNiceMock(InterfaceToMock.class);           AndroidMock.expect(instance.SimpleMethod()).andStubReturn("Hello!");            
        MyModule myMockModule = new MyModule();
        myMockModule.setMockedInstance(instance);//Comment this string to get into the test01() method          
        MyApplication.setMyModule(myMockModule);
        super.setUp();
    }
    public void test01() {
        //It never comes here
    }
}

Module source code:

public class MyModule extends AbstractAndroidModule {
        protected InterfaceToMock mockedInstance;
        public void setMockedInstance(InterfaceToMock mockedInstance) {
            this.mockedInstance = mockedInstance;
        }
        @Override
        protected void configure() {
            if(mockedInstance != null)
                bind(InterfaceToMock.class).toInstance(mockedInstance);
        }
    }

不幸的是，如果 RoboGuice 和 RoboGuice 的设置步骤出现问题，单元测试，你可能会得到这种错误。没有神奇的简短答案，而是一组需要严格遵循的步骤。

顺便说一句，您正在使用 RoboGuice 1.1 - AbstractAndroidModule & RoboUnitTest 在 RoboGuice 2.0 中不再存在。 RoboGuice 1.1 已弃用，因此最好的整体解决方案是根据这些说明迁移到最新版本升级到 2.0 。

但是，以防万一您使用的是 RoboGuice 1.1，请遵循以下一些步骤：

在重构/更改包名称等后，不要生成不一致的生成代码/构建文件。删除生成的代码，执行清理和删除操作。构建，甚至重新创建一个新项目并复制源文件。
将您的应用程序代码放在一个项目中（依赖于 RoboGuice，独立于 Instrumentation/RoboUnitTestCase/AndroidMock）。您的应用程序代码项目在 lib 中包含：guice-2.0-no_aop.jar 和 roboguice-1.1.2.jar。
将单元测试代码放在引用它的另一个项目中（独立于 RoboGuice，独立于 Instrumentation/RoboUnitTestCase/AndroidMock）。此处为开始之前的说明。您的测试代码项目包含在 lib 中：AndroidMockGenerator.jar。

在您的应用程序项目中，您的应用程序 + 模块类如下所示：

package com.mypackage;

导入 android.app.Instrumentation；
导入 android.content.Context；

公共类 MyApplication 扩展 roboguice.application.RoboApplication {

静态 MyModule myModule；    

// 这个构造函数通常由应用程序调用
公共MyApplication（上下文上下文）{
    极好的（）;
    AttachBaseContext(上下文);
}
// 这个构造函数由单元测试调用。不幸的是，这只是少量 
// 单元测试需求的“抽象泄漏”到应用程序代码中。
公共MyApplication（仪器仪表）{
    极好的（）;
    AttachBaseContext(instrumentation.getContext());
}    
公共静态无效setModule（MyModule模块）{
    MyApplication.myModule = 模块；
}   
公共静态 MyModule getModule() {
    返回MyApplication.myModule；
}   
}

还有

package com.mypackage;

公共类 MyModule 扩展 roboguice.config.AbstractAndroidModule {
// 这将被注入
受保护的 UsefulObject myUsefulInstance；    

公共无效setUsefulObject（UsefulObject有用实例）{
    this.myUsefulInstance =有用实例；
}    
公共 UsefulObject getUsefulObject() {
    返回 this.myUsefulInstance；
}    

@覆盖
受保护的无效配置（）{
    绑定(UsefulObject.class).toInstance(myUsefulInstance);
}

}

在您的测试项目中，您的测试用例类看起来像这样：

导入 android.test.suitebuilder.annotation.LargeTest;    
导入 com.mypackage.MyApplication;    
导入 com.mypackage.MyModule;    
导入 com.mypackage.UsefulObject；

确保对于测试项目，AndroidManifest.xml 文件具有以下条目：

 

在运行测试之前，请先运行另一个简单的“Hello World”应用程序，确保模拟器已启动并运行正常。成功后，运行您的应用程序。最后，运行您的测试项目。

之后应该可以工作。祝你好运&让我知道！

Unfortunately, if there's an issue with the setup steps for RoboGuice & unit testing, you can get this sort of error. No magic short answer, but rather a set of steps to follow exactly.

BTW, you're using RoboGuice 1.1 - AbstractAndroidModule & RoboUnitTest no longer exist in RoboGuice 2.0. RoboGuice 1.1 is deprecated, so best overall solution is to move to newest version according to these instructions Upgrading to 2.0.

However, just in case you're attached to RoboGuice 1.1, here's some steps to follow:

Don't have inconsistent generated code/build files after refactoring/changing package names etc. Delete generated code, do a Clean & Build, even recreate a new project and copy source files in.
Have your app code in one project (RoboGuice dependent, Instrumentation/RoboUnitTestCase/AndroidMock independent). You app code project has within lib: guice-2.0-no_aop.jar and roboguice-1.1.2.jar.
Have your unit test code in another project that references it (RoboGuice independent, Instrumentation/RoboUnitTestCase/AndroidMock independent). Instructions here Before You Get Started. Your test code project has within lib: AndroidMockGenerator.jar.

In your app project, your App + Module classes look something like this:

package com.mypackage;

import android.app.Instrumentation;
import android.content.Context;

public class MyApplication extends roboguice.application.RoboApplication {

static MyModule myModule;    

// this constructor usually called by app
public MyApplication(Context context) {
    super();
    attachBaseContext(context);
}
// This constructor called by unit tests.  This is unfortunately small amount of 
// 'abstraction leakage' of unit test needs into app code.
public MyApplication(Instrumentation instrumentation) {
    super();
    attachBaseContext(instrumentation.getContext());
}    
public static void setModule(MyModule module) {
    MyApplication.myModule = module;
}   
public static MyModule getModule() {
    return MyApplication.myModule;
}   
}

And

package com.mypackage;

public class MyModule extends roboguice.config.AbstractAndroidModule {
// this will be injected
protected UsefulObject myUsefulInstance;    

public void setUsefulObject(UsefulObject usefulInstance) {
    this.myUsefulInstance = usefulInstance;
}    
public UsefulObject getUsefulObject() {
    return this.myUsefulInstance;
}    

@Override
protected void configure() {
    bind(UsefulObject.class).toInstance(myUsefulInstance);
}

}

In your test project, your test case class looks something like this:

import android.test.suitebuilder.annotation.LargeTest;    
import com.mypackage.MyApplication;    
import com.mypackage.MyModule;    
import com.mypackage.UsefulObject;    
 //import com.mypackage.UsefulObjectSimpleImplementation;    
import android.test.suitebuilder.annotation.MediumTest;    
import android.test.suitebuilder.annotation.SmallTest;    
import com.google.android.testing.mocking.AndroidMock;    
import roboguice.test.RoboUnitTestCase;

public class TestMyModule extends RoboUnitTestCase<MyApplication> {

@Override
protected void setUp() throws Exception {
    UsefulObject instance = // new UsefulObjectSimpleImplementation(); 
                            AndroidMock.createNiceMock(UsefulObject.class);           
    MyModule mockModule = new MyModule();
    mockModule.setUsefulObject(instance);
    MyApplication.setModule(mockModule);
    super.setUp();
}

// Make sure you use one of the @*Test annotations AND begin
// your testcase's name with "test"
@MediumTest
public void test01() {
    AndroidMock.expect(MyApplication.getModule().getUsefulObject().
         simpleMethod()).andStubReturn("Hello!");
}

}

Ensure that for the test project, the AndroidManifest.xml file has the following entry:

   <instrumentation android:name="android.test.InstrumentationTestRunner"
     android:targetPackage="com.mypackage"
     android:label="Tests for com.mypackage"/>

Before running your test, ensure your emulator is started and is running healthily, by running a different, simple "Hello World" app first. When this succeeds, then run your app. Lastly, run your test project.

Should work after this. Best of luck & let me know!
