Grails不能使用Spock框架？

Question

我目前正在处理一个没有 TDD 的项目，现在我已采取以下步骤开始使用 Spock 对该项目进行单元和集成测试：

1. 在 buildconfig 中添加了以下内容：

   测试 ":spock:0.7"

2. 然后在 "test/unit/MYCLASSNAME" 处创建了一个名为 MyfunctionControllerSpec 的规范，如下所示：

   import grails.test.mixin.*
   import spock.lang.Specification
   
   class MyfunctionControllerSpec extends Specification {
   
       void "list() should return no results with no records in DB"() {
           given:
               def model = controller.list()
           expect:
               model.taskInstanceList.size() == 0
               model.taskInstanceTotal == 0
       }
   
   }
   

但是，规范导入行出现以下错误：

Groovy:unable to resolve class spock.lang.Specification

我不明白我做错了什么，我是否导入或安装了 Spock 错误？

提前致谢

我尝试了下面的建议，然后解决方案无法运行，它仍然无法识别规范类，即使当我开始输入“inport spo”并按 cntrl+space 时也没有出现，就好像它甚至无法识别插件一样：

Answer 1

您使用的是 Grails 2.1.0，而 Groovy 2.0 是在 Grails 2.2.0 及更高版本中引入的。希望您不需要显式依赖org.spockframework:spock-grails-support:0.7-groovy-2.0。只能如下使用：

plugins{
    test ":spock:0.7"
}

如果您仍然发现问题，则通过创建一个全新的裸骨 grails 应用程序来隔离问题，并按照插件文档中的说明安装插件。尝试查看是否有任何类路径冲突。如果问题仍然存在，请清除 ivy-cache 和/或 .m2 并重试。

Answer 2

我几乎在这里回答了这个问题，但我看到您使用的是 Grails 2.1。

对于使用 Grails 2.2.x 遇到此错误的其他人，请参阅answer
