Android Espresso 测试:找不到类:...空测试套件 [英] Android Espresso test: Class not found: ...Empty test suite
问题描述
我正在尝试从这个例子中实现一些东西 - https://github.com/googlesamples/android-testing/tree/master/ui/espresso/BasicSample - 进入我的应用.
I'm trying to implement things from this example - https://github.com/googlesamples/android-testing/tree/master/ui/espresso/BasicSample - into my app.
当我尝试执行简单的 Espresso 测试时,会发生这种情况:
When I try to execute the simple Espresso test, this happens:
"/Applications/Android Studio 2.2.3.app/Contents/jre/jdk/Contents/Home/bin/java" (...)
"/Applications/Android Studio 2.2.3.app/Contents/jre/jdk/Contents/Home/bin/java" (...)
进程以退出代码 1 结束未找到类:com.faces_shop.app.MainActivityTest"空测试套件.
Process finished with exit code 1 Class not found: "com.faces_shop.app.MainActivityTest"Empty test suite.
(从 Android Studio 复制粘贴)
(copy-pasted from Android Studio)
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;
/**

*/
@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)));
}
}
应用的 build.gradle:
The app's 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:
The top-level 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?
为什么看不到测试类?
它在androidTest的这个路径中:.../Examples/DynamicList/FacesApp/src/androidTest/java/com/faces_shop/app/MainActivityTest.java
It is in this path in androidTest : .../Examples/DynamicList/FacesApp/src/androidTest/java/com/faces_shop/app/MainActivityTest.java
推荐答案
回答我自己的问题:
解决方案
事实证明,Android Studio 中有一个运行/调试配置,为 JUnit",而它应该是 Android 测试".
Turns out, that there was a Run/Debug Configuration in Android Studio, as "JUnit", whereas it should be "Android Tests".
发生这种情况是因为,最初,测试类意外地在 src/test/java 中,而不是 src/androidTest/java.因此,当我最初运行它时,运行/调试配置文件被创建为 JUnit,然后在随后尝试运行该类时被重用.我想它可以在 Android Studio 中改进,根据类的当前状态来确定运行/调试类型(虽然不是抱怨;-))...
This happened because, initially, the test class was, accidentally in src/test/java, instead of src/androidTest/java. So, when I've run it initially, the Run/Debug profile was created as JUnit and then got reused with subsequent attempts to run the class. I guess it could be improved in Android Studio, to determine the Run/Debug type based on the current state of the class (not complaining, though ;-))...
