我试图用roboletric构建非常简单的单元测试,但我无法创建活动。
我试了一下网上的建议,但没有成功。
调用Robolectric.buildActivity((时出现资源$NotFoundException
然而,我使用的是4.0.1版本。我想知道是否有一些额外的设置,我需要做。
这是我的成绩:
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
testImplementation 'androidx.test.espresso:espresso-core:3.1.0'
testImplementation 'androidx.test:core:1.0.0'
testImplementation 'androidx.test.ext:junit:1.0.0'
testImplementation 'junit:junit:4.12'
testImplementation 'org.mockito:mockito-core:2.23.0'
testImplementation 'org.robolectric:robolectric:4.0.1'
androidTestImplementation 'com.google.truth:truth:0.42'
testImplementation 'com.google.truth:truth:0.42'
androidTestImplementation 'com.android.support.test:rules:1.0.2'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
}
和我的测试程序:
@Config(sdk = 28, manifest=Config.NONE)
@RunWith(RobolectricTestRunner.class)
public class MainActivityTest {
private Activity activity;
@Before
public void setup() {
try {
// I tried these 3 lines of code and they all throw the exception :(
//activity = Robolectric.buildActivity(MainActivity.class).create().get();
//activity = Robolectric.setupActivity(MainActivity.class);
activity = Robolectric.buildActivity(MainActivity.class).create().start().resume().get();
}
catch (Exception e)
{
System.out.println("Keeps throwing exception!");
}
}
}
这里的输出:
[Robolectric] com.guitarv.robotest.MainActivityTest.validateTextViewContent: sdk=28; resources=legacy
[Robolectric] NOTICE: legacy resources mode is deprecated; see http://robolectric.org/migrating/#migrating-to-40
Keeps throwing exception!

我确实点击了那个链接,并将grade.properties更新为:
org.gradle.jvmargs=-Xmx1536m
# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
# org.gradle.parallel=true
android.enableUnitTestBinaryResources=true
但没有成功。我仍然无法创建活动,并且遗留模式消息不断显示。
有什么线索表明我做错了什么?
谢谢。
Robolectric找不到应用程序的资源。
将其添加到您的build.gradle
:
android {
testOptions {
unitTests.includeAndroidResources = true
}
}
将此添加到您的gradle.properties
(Android Studio 3.3+不需要(:
android.enableUnitTestBinaryResources=true
我在使用Robolectric 4.2时遇到了这个问题。升级到4.2.1解决了这个问题。
