带有Multidex应用的Android Espresso 2.0空测试套件问题

Question

在尝试使用multidex应用程序运行espresso 2.0时遇到了实际问题，我一直继续进行消息测试，然后退出并说空的测试套件

  Success 

  Running testsTesting started at 08:56 ...

  Test running startedFinish
   Disconnected from the target VM, address: 'localhost:8601', transport:     'socket'

这是我的项目组织

我的测试用例

@LargeTest
 public class MainActivityInstrumentTest
    extends ActivityInstrumentationTestCase2<MainActivity> {

private MainActivity mActivity;

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

@Before
public void setUp() throws Exception {
    super.setUp();
    injectInstrumentation(InstrumentationRegistry.getInstrumentation());
    mActivity = getActivity();
}

@SmallTest
public void checkPreconditions() {
    assertThat(mActivity, notNullValue());
    assertThat(getInstrumentation(), notNullValue());
    onView(withId(R.id.txtUsername))
            .perform(typeText("Steve"));
}

@After
public void tearDown() throws Exception {
    super.tearDown();
}
}

Answer 1

要测试启用了Multidex的应用程序，您需要使用其他testInstrumentationRunner

android {
  defaultConfig {
  ...
  testInstrumentationRunner "com.android.test.runner.MultiDexTestRunner"
  }
}

对于低于1.1的Android Plugin for Gradle版本，您需要添加以下依赖项：

dependencies {
    androidTestCompile('com.android.support:multidex-instrumentation:1.0.1') {
         exclude group: 'com.android.support', module: 'multidex'
    }       
}

Answer 2

将您的测试文件夹从instrumentTest重命名为androidTest 。
