[2016-04-04 04:44:00 - UiTests] Test run failed: Instrumentation run failed due to 'java.lang.RuntimeException'

TestClass

package android.support.v7.appcompat.test;

import com.android.uiautomator.core.UiObject;
import com.android.uiautomator.core.UiObjectNotFoundException;
import com.android.uiautomator.core.UiSelector;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;

public class DMTest extends UiAutomatorTestCase
{
    public void testDemo() throws UiObjectNotFoundException
    {
        // setText
        new UiObject(new UiSelector().description("edittext_brute")).setText("bazinga");

        // clickButton
        //new UiObject(new UiSelector().description("button_done")).click();

        UiObject btDone = new UiObject(new UiSelector().description("button_done"));
        btDone.click();
    }

}

清单

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="android.support.v7.appcompat.test"
    android:versionCode="1"
    android:versionName="1.0" >

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

    <instrumentation
    android:name="android.test.InstrumentationTestRunner"
    android:targetPackage="com.example.sony.reel" />

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

</manifest>

即使testDemo()构造函数中没有代码，它也会给出相同的异常

Edit 1: It gives the same exception even if there is no code within the testDemo() constructor

推荐答案

Android recommends to use studio for uiautomator test projects and gradle for building.

在您的情况下，请尝试在测试类定义的开头添加@RunWith(AndroidJUnit4.class)注释.

In your case try adding @RunWith(AndroidJUnit4.class) annotation at the beginning of your test class definition.

如果将其移至Studio，您的代码示例肯定会起作用.或使用ant进行编译并使用已编译的jar文件运行.

Your code sample will definitely work if you move this to studio. Or compile with ant and run with compiled jar file.
