Question

我尝试将此示例中的内容 - https://github.com/googlesamples/android-testing/tree/master/ui/espresso/BasicSample - 实施到我的应用中。

当我尝试执行简单的Espresso测试时，会发生这种情况：

＆＃34; / Applications / Android Studio 2.2.3.app/Contents/jre/jdk/Contents/Home/bin/java" （...）

流程以退出代码1结束   未找到类：＆＃34; com.faces_shop.app.MainActivityTest＆＃34;空测试套件。

（从Android Studio复制粘贴）

测试：

package com.faces_shop.app;

import android.support.test.filters.LargeTest;
import android.support.test.rule.ActivityTestRule;
import android.support.test.runner.AndroidJUnit4;

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.action.ViewActions.closeSoftKeyboard;
import static android.support.test.espresso.action.ViewActions.typeText;
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 AnonymizedForReview on 2017-01-12.
 */
@RunWith(AndroidJUnit4.class)
@LargeTest
public class MainActivityTest {

    public static final String STRING_TO_BE_TYPED = "Espresso";

    @Rule
    public ActivityTestRule<MainActivity> mActivityRule = new ActivityTestRule<>(
            MainActivity.class);

    @Test
    public void changeText_sameActivity() {
        // Type text and then press the button.
        onView(withId(R.id.editFilter))
                .perform(typeText(STRING_TO_BE_TYPED), closeSoftKeyboard());
//        onView(withId(R.id.changeTextBt)).perform(click());

        // Check that the text was changed.
        onView(withId(R.id.editFilter)).check(matches(withText(STRING_TO_BE_TYPED)));
    }


}

应用程序的build.gradle：

apply plugin: 'com.android.application'

android {
//    productFlavors {
//        /* https://android-developers.googleblog.com/2015/12/leveraging-product-flavors-in-android.html */
//        mock {
//            applicationIdSuffix = ".mock"
//        }
//        prod
//    }
    compileSdkVersion 25
    buildToolsVersion "25.0.0"
    defaultConfig {
        applicationId "com.faces_shop.app"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile project(':FacesApi')

//    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
//        exclude group: 'com.android.support', module: 'support-annotations'
//    })
    // Testing-only dependencies
    // Force usage of support annotations in the test app, since it is internally used by the runner module.
    androidTestCompile 'com.android.support:support-annotations:' + rootProject.supportLibVersion;
    androidTestCompile 'com.android.support.test:runner:' + rootProject.runnerVersion;
    androidTestCompile 'com.android.support.test:rules:' + rootProject.rulesVersion;
    androidTestCompile 'com.android.support.test.espresso:espresso-core:' + rootProject.espressoVersion;

    compile 'com.android.support:appcompat-v7:25.0.1'
    compile 'com.android.support:recyclerview-v7:25.0.1'
    testCompile 'junit:junit:4.12'
}

顶级build.gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

ext {
    buildToolsVersion = "24.0.1"
    supportLibVersion = "25.0.1"
    runnerVersion = "0.5"
    rulesVersion = "0.5"
    espressoVersion = "2.2.2"
}

我做错了什么？

为什么没有看到测试类？

在androidTest的这个路径中：... / Examples / DynamicList / FacesApp / src / androidTest / java / com / faces_shop / app / MainActivityTest.java

回答我自己的问题：

<强>解决方案

事实证明，Android Studio中有一个运行/调试配置，如＆＃34; JUnit＆＃34; ，而它应该是＆＃34; Android Tests＆＃34 ;

这是因为，最初，测试类是在src / test / java中，而不是src / androidTest / java。因此，当我最初运行它时，Run / Debug配置文件被创建为JUnit，然后在后续尝试运行该类时重用。我想可以在Android Studio中进行改进，根据类的当前状态确定Run / Debug类型（不抱怨，但是， - ））...

Android Espresso测试：未找到类：...空测试套件
