与安卓的Gradle整合工作室始终roboelectric给人包org.junit不存在错误 [英] Integrating roboelectric with android studio with gradle always gives package org.junit does not exist error

问题描述

我想roboelectric在我的新项目进行整合。我用以下链接了解和impliment roboelectric

I am trying to integrate roboelectric in my new project . I used following links to understand and impliment roboelectric

的http：// pivotallabs .COM /设置-UP-robolectric功能于Android的工作室-1-1-ON-OS-X /

的http：// nenick- android.blogspot.in/2015/02/android-studio-110-beta-4-and.html

但我刚开上运行我的测试类以下错误

But I am gettin following error on running my test class

加我下面的测试类code

Added below my test class code

 import android.app.AlertDialog;
import android.widget.Button;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.RobolectricTestRunner;
import org.robolectric.annotation.Config;
import org.robolectric.shadows.ShadowAlertDialog;

import static org.hamcrest.CoreMatchers.is;
import static org.hamcrest.CoreMatchers.notNullValue;
import static org.junit.Assert.assertThat;
import static org.robolectric.Robolectric.clickOn;
import static org.robolectric.Robolectric.setupActivity;
import static org.robolectric.RobolectricBase.shadowOf;


@RunWith(RobolectricTestRunner.class)
@Config(manifest = "app/src/main/AndroidManifest.xml", emulateSdk = 18)
public class SampleTest {


    @Test
    public void buttonTapDisplaysAnAlertDialog() {
        MainActivity helloActivity = setupActivity(MainActivity.class);

        Button button = (Button) helloActivity.findViewById(R.id.button);

        clickOn(button);

        AlertDialog latestAlertDialog = ShadowAlertDialog.getLatestAlertDialog();
        assertThat(latestAlertDialog, is(notNullValue()));

        ShadowAlertDialog shadowAlertDialog = shadowOf(latestAlertDialog);
        assertThat(shadowAlertDialog.getTitle().toString(), is("Hi"));
    }




}

和我的应用程序文件的gradle是

and my app gradle file is

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "21.1.2"



    defaultConfig {
        applicationId "com.example.junittestapp"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets { main { java.srcDirs = ['src/main/java', 'src/test/java/'] } }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:support-v4:22.1.1'
    testCompile 'junit:junit:4.12'
    testCompile 'org.robolectric:robolectric:2.4'
}

我发现同样的错误，在这个博客太

i found same error in this blog too

<一个href=\"https://discuss.gradle.org/t/why-cant-my-simplest-one-line-build-gradle-compile-tests-with-junit-jar/1868\" rel=\"nofollow\">https://discuss.gradle.org/t/why-cant-my-simplest-one-line-build-gradle-compile-tests-with-junit-jar/1868

我认为我丢失的东西，我搜索了很多无法找到一个解决方案，任何帮助将AP preciable。

I think something i am missing ,i searched a lot couldnt find a solution ,any help will appreciable.

在此先感谢

推荐答案

您的问题是，你有一个 sourceSet 的宣布为包含code为应用程序的主和测试。这就是为什么摇篮任务：应用程序：compileDebugJava'，因为它不具备 的junit.jar 的在那一刻（它在注射 testCompile - 时间）。声明两个不同的sourceSet的，一切都应该工作。

Your problem is that you have one sourceSet declared as main that contains code for application and for test. That's why Gradle task ':app:compileDebugJava' fails because it doesn't have junit.jar at that moment (it's injected at testCompile - time). Declare two different sourceSet's and everything should work.

sourceSets {
    main {
        java.srcDirs = ['src/main/java']
    }
    robolectric {
        java.srcDir file('src/test/java/')
        resources.srcDir file('src/test/resources')
    }
}
