【Androidstudio】kotlin class org.greenrobot.greendao.test.DbTest, unresolved supertypes: android.test

问题描述

kotlin项目中引入GreenDao数据库，在编译并运行时出现如下问题：

Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
class org.greenrobot.greendao.test.DbTest, unresolved supertypes: android.test.AndroidTestCase

原因分析：

缺少：android.test.AndroidTestCase

笔者的项目是引入的依赖库是androidx，而GreenDao数据库的测试类依赖的是android包，所以在model项目的build.gradle文件下添加：

useLibrary 'android.test.runner'
useLibrary 'android.test.base'
