Android Studio无法识别Espresso导入

Question

我正在尝试使用Espresso编写测试用例.

我使用的是Android Studio 1.5.1(稳定频道),Gradle插件1.5,Gradle 2.7.问题是Android Studio无法识别任何与Espresso相关的导入(并且不仅仅是)

所以,我试图清理项目,重建,使缓存无效并重新启动,但没有.

我在我的app模块中添加了这些依赖项:

androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
androidTestCompile 'com.android.support:support-annotations:23.1.1'
androidTestCompile 'com.android.support.test:runner:0.4.1'
androidTestCompile 'com.android.support.test:rules:0.4.1'

我在defaultConfig中添加了runner:

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

我在androidTest文件夹下创建了测试套件类:

我做错了什么？

UPDATE

这是我的build.gradle的(部分):

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'

Answer 1

更新2016年11月30日

就像@Jaymes Bearden在下面的评论中所说的那样.

使用testBuildType.Android Studio 2.2,gradle 2.2.2

android {
        testBuildType "yourBuildType"
}

老答复

我发现不是解决方案,而是一些问题的根源.在我的项目中,我有很多BuildTypes.特别是多个调试版本.

一切都只适用于默认的调试构建类型.我认为这是一些内部Android Studio错误.

我的AS版本 - 2.1

Answer 2

也许您的Build Variant处于“发布”模式。您必须将其更改为调试。

Answer 3

在 Android Studio 中：

打开“运行”菜单 -> 编辑配置 - 添加新的 Android 测试配置 - 选择模块 添加特定的仪器运行程序：

android.support.test.runner.AndroidJUnitRunner

还可以尝试从 SDK Manager 更新 Android 支持库。
