是否有人可以告诉我我做错了什么?

您似乎没有将Junit-Package添加到模块的 build.gradle 文件中。只需在依赖项块中添加它,它应该可以工作:
androidTestCompile 'junit:junit:4.12'
testCompile 'junit:junit:4.12'
答案 1 :(得分:4)
当我从头开始创建一个新模块时,Android studio将生成一个默认的gradle文件,其中包含以下与测试相关的依赖项:
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
这似乎可以解决构建日志中的至少一些依赖性问题。由于缺少org.junit
引用,可能还需要将junit添加为androidTestCompile
依赖项,因为@Chris已经回答了;或者它可能含在espresso中。

您的gradle构建中可能缺少依赖项,将这些依赖项添加到行:
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:0.5'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:2.2.2'
