我真的害怕发布这个,但我没有在谷歌上发现任何与之相关的内容,所以我猜这是一个菜鸟问题。
我想用Espresso来测试我的Android应用程序。
我尝试下载示例项目,创建一个简单的项目并按照Android开发人员网站中的描述实现它,但我无法启动并运行。
手动添加静态导入后,我已经通过示例测试解决了所有编译问题。 但是当我运行它时,我明白了:

androidTestCompile
- androidTest 文件夹 - ui测试
testCompile
- 测试文件夹 - 单元测试
Unit
测试:添加:
testCompile 'junit:junit:4.12'
要:
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:22.0.0'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.0'
androidTestCompile 'com.android.support.test:testing-support-lib:0.1'
testCompile 'junit:junit:4.12' // <-- added
}
Espresso
测试:删除Junit和注释。

public MainActivityTest(){
