我像这里一样注释了我的类(class)
@RunWith(AndroidJUnit4.class)
public class WorkdayProviderTest
此外,还像这样注释了我的测试方法
@Test
public void insert_dataInsertsCorrectly()
最后,像这样配置我的 build.gradle defaultConfig 和依赖项
defaultConfig {
applicationId 'com.jueggs.workinghours'
minSdkVersion 16
targetSdkVersion 23
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
androidTestCompile "junit:junit:4.12"
androidTestCompile "com.android.support:support-annotations:23.3.0"
androidTestCompile "com.android.support.test:runner:0.4.1"
androidTestCompile "com.android.support.test:rules:0.4.1"
androidTestCompile "com.android.support.test.espresso:espresso-core:2.2.1"
androidTestCompile "com.android.support.test.espresso:espresso-contrib:2.2.1"
androidTestCompile "org.hamcrest:hamcrest-library:1.3"
并像这样配置测试运行
它告诉我
No tests were found
Test running failed: Instrumentation run failed due to 'java.lang.ClassNotFoundException'
如何解决这个问题?
最佳答案
您的 Gradle 依赖项中可能没有任何内容。您是否正确声明了 com.android.support.test:runner
(可选 com.android.support.test:rules
)?
请看一下我的 build.gradle

编辑:问题出在注释上,请执行以下解决方案之一:
@RunWith(AndroidJUnit4.class)
@RunWith(AndroidJUnit4.class)
@RunWith(JUnit4.class)
测试包中似乎没有更多的
AndroidJUnit4.class
了。关于未找到 AndroidJUnit4 测试,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/37087004/
