Kotlin – Mockito不能模拟/间谍（Spring REST API）

由于Kotlin中的所有课程都是默认的最终课程，所以Mockito不能窥探最后的课程：

 Cannot mock/spy class bye.persistence.jdbcTrial Mockito cannot mock/spy following: - final classes - anonymous classes - primitive types 

而这个指南 （7月6日，丹尼·布鲁斯勒（Danny Preussler））说，一个框架是解决这个问题的必要条件。

现在我想知道，是否有可能测试一个REST API（使用Spring MockMvc）。 以下是我的测试代码：

 package byeTest.persistenceTest import bye.domain.User import bye.persistence.jdbcTrial import bye.spring.GreetingController import byeTest.persistenceTest.RestAPITest.RootConfig import org.junit.Before import org.junit.Test import org.junit.runner.RunWith import org.mockito.BDDMockito.given import org.mockito.Mockito import org.springframework.beans.factory.annotation.Autowired import org.springframework.context.annotation.Bean import org.springframework.context.annotation.Configuration import org.springframework.http.MediaType import org.springframework.test.context.ContextConfiguration import org.springframework.test.context.junit4.SpringJUnit4ClassRunner import org.springframework.test.context.web.WebAppConfiguration import org.springframework.test.web.servlet.MockMvc import org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get import org.springframework.test.web.servlet.result.MockMvcResultMatchers.content import org.springframework.test.web.servlet.setup.MockMvcBuilders import org.springframework.web.context.WebApplicationContext @RunWith(SpringJUnit4ClassRunner::class) @ContextConfiguration(classes = arrayOf(RootConfig::class)) @WebAppConfiguration open class RestAPITest { var mockMvc: MockMvc? = null; @Autowired var wac : WebApplicationContext? = null; @Autowired var jdbcTrial : jdbcTrial? = null @Autowired var todoServiceMock : GreetingController? = null; @Before open fun setup(){ mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build() given(this.jdbcTrial?.getUserById(2)).willReturn(User(2,"uname","typ")); } @Test open public fun find_2(){ mockMvc!!.perform(get("/user/2").accept(MediaType.APPLICATION_JSON)) .andExpect(content().string("{\"id\":2,\"username\":\"uname\",\"usertype\":\"typ\"}")) } @Configuration open class RootConfig{ @Bean open fun jdbcTrial():jdbcTrial{ return Mockito.mock(jdbcTrial::class.java) } } } 

我设置了所有用于open的函数和类，因为根据kotlin文档，这与final是完全相反的。 但是使用这个（到处都是）仍然会抛出上面提到的异常。

 import bye.domain.Comment import bye.domain.Event import bye.domain.Participant import bye.domain.User import java.sql.Connection import java.sql.DriverManager import java.sql.ResultSet import java.sql.Statement import java.util.ArrayList import javax.sql.DataSource open class jdbcTrial() { open var url: String = "jdbc:postgresql://rosdel.quintor.local:5432/quintorevents" //val props: Properties = Properties(); open var DB_DRIVER = "org.postgresql.Driver"; open var dataSource:String? = "b"; constructor(s : String):this(){ this.dataSource = s } open fun getFoo():String{ var query : String = "select val_col from foo_tbl where key_col = 'foo';" var rs:ResultSet = this.getConnection().createStatement().executeQuery(query) var result:String = "wrong"; while(rs.next()){ result= rs.getString("val_col") } return result; } open fun getBaz():String{ return "qux" } // /events open fun getAll(): List<Event> { return getMultipleEvents("select * from quintor_event;") } // /events/search open fun searchEvents(search: String): List<Event> { var query = "select * from quintor_event where title LIKE '%" + search + "%';" return getMultipleEvents(query) } // used for getting the comments open fun getUserById(id: Int): User { var query = "select * from quintor_user where id = ${id};"; return getSingleUser(query) } ........
