Question

我使用Android studio verison 2.3.1，我想使用espresso进行测试，但遇到问题如下图Test running failed

我的测试java文件

package com.view.asim;

import android.support.test.filters.LargeTest;
import android.support.test.rule.ActivityTestRule;
import android.support.test.runner.AndroidJUnit4;
import com.view.asim.activity.MainActivity;
import org.junit.Before;
import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;
import static android.support.test.espresso.Espresso.onView;
import static android.support.test.espresso.assertion.ViewAssertions.matches;
import static android.support.test.espresso.matcher.ViewMatchers.withId;
import static android.support.test.espresso.matcher.ViewMatchers.withText;

/**
 * Created by OF on 2017/4/28.
 */

@RunWith(AndroidJUnit4.class)
@LargeTest
public class MakeSureLogin {
    private String mStringToBetyped;
    @Rule
    public ActivityTestRule<MainActivity> mActivityRule = new ActivityTestRule<>(
            MainActivity.class);

    @Before
    public void initValidString() {
        // Specify a valid string.
    }

    @Test
    public void changeText_sameActivity() {

        // Check that the text was changed.
        onView(withId(R.id.account_txt)).perform().check(matches(withText(mStringToBetyped)));

    }
}

我知道stackoverflow中有类似的问题已经被问过，而且有些人也有问题，但这些解决方案（如this）无法解决我的问题。有人说可以specific instrumentation runner，但Android工作室版本2.3中没有动作。我认为它可能与multildex相关，真的希望有些人可以帮助我，任何建议都会非常感激。这是我的build.gralde档案

    defaultConfig {
       //...
       multiDexEnabled true
       testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
       //...
    }
    productFlavors {
           zixuntong{
                applicationIdSuffix ".mixuntong"
                manifestPlaceholders = otherHolderMap
                manifestPlaceholders.put("PACKAGE_NAME",ASIM_PKG_NAME+applicationIdSuffix)
                buildConfigField "boolean", "isAddShare", "false"
                buildConfigField "boolean", "isZXT", "true"
            }
    }
        //.....
        androidTestZixuntongCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
                exclude group: 'com.android.support', module: 'support-annotations'
            })




   //    compile 'com.android.support:support-annotations:22.2.0'
        androidTestZixuntongCompile 'com.android.support.test:runner:0.5'
        testCompile 'junit:junit:4.12'
        androidTestZixuntongCompile('com.android.support:multidex-instrumentation:1.0.1') {
            exclude group: 'com.android.support', module: 'multidex'
        }
        configurations.all {
            resolutionStrategy.force 'com.android.support:support-annotations:23.1.0'
        }
    //...

//had trying follow script,but still doesn't work
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',
{ 排除组：'com.android.support'，模块：'support-annotations' }）

Answer 1

我发现在将Android Studio从2.3.1升级到2.3.2之后我已修复此问题。

测试运行失败：无法找到以下内容的检测信息：ComponentInfo {com.view.asim.mixuntong.test / android.test.InstrumentationTestRunner}
