无法运行android的espresso测试

Question

我有一些问题设置/运行espresso测试的Android。我的TestClass如下所示：-

import static com.google.android.apps.common.testing.ui.espresso.Espresso.onView;
import static com.google.android.apps.common.testing.ui.espresso.action.ViewActions.click;
import static com.google.android.apps.common.testing.ui.espresso.assertion.ViewAssertions.matches;
import static com.google.android.apps.common.testing.ui.espresso.matcher.ViewMatchers.withId;
import static com.google.android.apps.common.testing.ui.espresso.matcher.ViewMatchers.withText;
import android.test.ActivityInstrumentationTestCase2;
import android.util.Log;

import com.sample.rasmus.MainActivity;

public class BasicTest extends ActivityInstrumentationTestCase2<MainActivity> {

public BasicTest(String name) {
    super(MainActivity.class);
    Log.v("amtesting","2");
}
 @Override
  public void setUp() throws Exception {
      Log.v("amtesting","5");
    super.setUp();
    Log.v("amtesting","4");
    // Espresso will not launch our activity for us, we must launch it via getActivity().
    getActivity();
  }

public void testSimpleClickAndCheckText(){
    Log.v("amtesting","1");
    onView(withId(com.sample.rasmus.R.id.thebutton)).perform(click());
    onView(withId(com.sample.rasmus.R.id.helloworld)).check(matches(withText("awesome")));
}

protected void tearDown() throws Exception {
    Log.v("amtesting","3");
    super.tearDown();

}

  }

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

<uses-sdk android:minSdkVersion="14" />

<instrumentation
    android:name="com.google.android.apps.common.testing.testrunner.GoogleInstrumentationTestRunner"
    android:targetPackage="com.sample.rasmus" />

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

 </manifest>

• 在设备仿真器-5554上启动检测Android.test.InstrumentationTestRunner
• 向Eclipse发送测试信息
• 测试完成

没有提到运行测试，测试也不会运行。我会错过什么？

Answer 1

这就是我最终解决它的方法。我将测试类的构造函数更改为下面：-

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

开始奏效了。奇怪的是，这是让我忙了一整天的原因。
