Android的功能测试与匕首

问题描述

我试图来测试的Mockito和功放的活动; 匕首。我已经能够在我的应用程序中注入依赖关系的活动，但测试活动的时候，我一直没能模拟的活动注入。我应该注入活性测试或让getActivity（）创建它吗？

 公共类MainActivityTest扩展
    ActivityInstrumentationTestCase2＆LT; MainActivity＆GT; {

@注入发动机engineMock;
私人MainActivity mActivity;
私人按钮mLogoutBtn;


公共MainActivityTest（）{
    超（MainActivity.class）;
}

@覆盖
保护无效设置（）抛出异常{
    super.setUp（）;

    //注入engineMock测试
    。ObjectGraph.create（新TestModule（））注资（本）;
}

@覆盖
保护无效的teardown（）{
    如果（mActivity！= NULL）
        mActivity.finish（）;
}

 @Module（
 包括= MainModule.class，
 入口点= MainActivityTest.class，
 覆盖=真
 ）

静态类TestModule {
    @Provides
    @Singleton
    发动机provideEngine（）{
        返回模拟（Engine.class）;
    }
}

@UiThreadTest
公共无效testLogoutButton（）{

    当（engineMock.isLoggedIn（））thenReturn（真）。

    mActivity = getActivity（）;
    mLogoutBtn =（按钮）mActivity.findViewById（R.id.logoutButton）;

    //如何在测试注入engineMock到活动？
    ObjectGraph.create（新TestModule（））注入（this.mActivity）。

    assertTrue（mLogoutBtn.isEnabled（）==真）;
}
}
 

解决方案

我用的Mockito和匕首进行功能测试。关键的概念是，你的测试类从ActivityUnitTestCase，而不是ActivityInstrumentationTestCase2继承;后者的超一流呼叫ONSTART（）活动的生命周期方法阻止你注入测试双打的依赖关系，但与第一次超一流的，你可以处理生命周期更精细。

您可以看到在使用匕首1.0.0和的Mockito测试活动和片段我的工作的例子：

I’m trying to test an Activity with Mockito & Dagger. I have been able to inject dependencies to Activity in my application but when testing the Activity, I have not been able to inject mock to the Activity. Should I inject Activity to test or let getActivity() create it?

public class MainActivityTest extends
    ActivityInstrumentationTestCase2<MainActivity> {

@Inject Engine engineMock;
private MainActivity mActivity;
private Button mLogoutBtn;


public MainActivityTest() {
    super(MainActivity.class);
}

@Override
protected void setUp() throws Exception {
    super.setUp();

    // Inject engineMock to test
    ObjectGraph.create(new TestModule()).inject(this);
}

@Override
protected void tearDown() {
    if (mActivity != null)
        mActivity.finish();
}

 @Module(
 includes = MainModule.class,
 entryPoints = MainActivityTest.class,
 overrides = true
 )

static class TestModule {
    @Provides
    @Singleton
    Engine provideEngine() {
        return mock(Engine.class);
    }
}

@UiThreadTest
public void testLogoutButton() {

    when(engineMock.isLoggedIn()).thenReturn(true);

    mActivity = getActivity();
    mLogoutBtn = (Button) mActivity.findViewById(R.id.logoutButton);

    // how to inject engineMock to Activity under test?
    ObjectGraph.create(new TestModule()).inject(this.mActivity);

    assertTrue(mLogoutBtn.isEnabled() == true);
}
}

解决方案

I use Mockito and Dagger for functional testing.The key concept is that your test class inherits from ActivityUnitTestCase, instead of ActivityInstrumentationTestCase2; the latter super-class call onStart() life-cycle method of Activity blocking you for inject your test doubles dependencies, but with first super-class you can handle the life-cycle more fine-grained.

You can see my working examples using dagger-1.0.0 and mockito for test Activities and Fragments in:

The project under test is in:
