Android Studio 未找到 TestCase 类 [英] TestCase class not found by Android Studio

问题描述

我编写了一个简单的测试用例类，并将其放置在 Android Studio 的默认测试目录中:src/androidTest".我创建了一个 Android 测试构建配置，用于查找模块中的所有测试.当我运行构建配置时，我的测试没有执行，我在 logcat 中收到以下消息:W/TestGrouping:无效包:'' 找不到或没有测试.如果我指定测试包甚至特定的测试类，我会收到类似的未找到类的消息.

I have written a simple test case class and placed it in the default test directory for Android Studio: "src/androidTest". I've created an Android Tests build configuration that looks for all Tests in the module. When I run the build configuration, my test does not execute and I get the following message in logcat: W/TestGrouping﹕ Invalid Package: '' could not be found or has no tests. If I specify the test package or even the specific test class, I get similar class not found messages.

我的测试类如下:

public class FirstTest extends InstrumentationTestCase {

public void testSample() {
        final int expected = 1;
        final int reality = 5;
        assertEquals(expected, reality);
    }
}

我的 build.gradle 文件如下所示:

My build.gradle file looks like this:

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:gridlayout-v7:19.0.1'
    compile 'com.android.support:support-v4:19.0.1'
    compile 'com.android.support:appcompat-v7:19.0.1'
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

我正在运行 0.9 版的 android gradle 插件.我的顶级 build.gradle(应用程序目录的对等点)看起来像这样.

I'm running version 0.9 of the android gradle plugin. My top level build.gradle (a peer to the app directory) looks like this.

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

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.9.+'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

我的项目目录结构如下:

My project directory structure is as follows:

<代码>应用源文件安卓测试爪哇主要的爪哇资源

推荐答案

androidTest/java目录下的包结构需要与main/java目录下的结构完全平行.

The package structure under the androidTest/java directory needs to exactly parallel the structure under the main/java directory.

我上面的问题是main下的包结构是com.mydomain.myapp.subpackage，androidTest下的目录结构是com.mydomain.myapp.subpackage.somethingelse.

My problem above was that the package structure under main was com.mydomain.myapp.subpackage and the directory structure under androidTest was com.mydomain.myapp.subpackage.somethingelse.

一旦包结构匹配，测试就会被发现并完美执行.

Once the package structures matched, the tests were discovered and executed flawlessly.
