如何运行./gradlew测试

Question

我正在尝试从命令行测试应用程序。当我从Android Studio运行测试时，一切正常。但是当我尝试运行命令时：

./gradlew test

我收到此错误：

Task 'test' not found in root project 'mvp_kotlin_example'.

使用./gradlew build或./gradlew clean我没有问题。我刚刚创建了一个项目来尝试./gradlew测试，它确实有效。

在mvp_kotlin_example中，我使用Robolectric进行测试，并使用Kotlin进行开发。

那么如何使我的测试从命令行运行呢？

这是一个开源项目，因此所有代码都可以在

这是我的build.gradle文件：

apply plugin: 'kotlin-android-extensions'
apply from: '../jacoco.gradle'

这里的问题与您build.gradle的项目无关，该项目缺少settings.gradle告诉gradle将app文件夹包含为模块的文件。我已经在您的项目上创建了PR＃1来解决此缺陷，合并后，您应该可以./gradlew clean test从项目根目录运行。

https://github.com/leandroBorgesFerreira/mvp-kotlin-example/pull/1

解决方案是将一个单行settings.gradle文件添加到根项目中，以声明构建中包含的模块。

$ cat settings.gradle 
include 'app'
