在将 Grails 2.5.1 应用程序升级到 Grails 3.0.6 后，我无法让我的单元测试再次运行。

我有一个非常简单的域类，叫做 Team .

class Team { 
 
   String name 
   String shortName 
   String image = 'noimage.jpg' 
 
   static constraints = { 
       name nullable: false, maxSize: 30, unique: true 
       shortName nullable: true, maxSize: 5 
       image nullable: false, maxSize: 30 
   } 
} 

以及执行此操作的单元测试

@TestMixin(HibernateTestMixin) 
@Domain([Team]) 
class TeamSpec extends Specification { 
 
    def setup() { 
        new Team(name: 'Hello', shortName: 'Big').save() 
    } 
 
    def cleanup() { 
    } 
 
    void "test something"() { 
        expect:"fix me" 
            !Team.findByName('hello') 
    } 
} 

当我执行单元测试时，出现以下运行时错误

groovy.lang.MissingMethodException: No signature of method: static abc.Team.findByName() is applicable for argument types: (java.lang.String) values: [hello] 
at abc.TeamSpec.test something(TeamSpec.groovy:24) 

它提示 Grails 2.5.x 中提供的动态查找器。谁能帮我解决这个问题？以前有人有过这种情况吗？

编辑

我创建了一个普通的新 Grails 3.0.6 并通过任务 create-domain-class 生成了一个域类.然后我在类中添加了三个String属性(name、shortName、image)并写了一个简单的断言 !Team.findByName('A')但异常(exception)仍然存在。

编辑 2
我仍然不知道我做错了什么。我将该问题报告给 Grails-Core issue tracker .示例代码可见 here

编辑 3 @TestFor做这项工作，但我想与 HibernateTestMixin 合作而不是 DomainClassUnitTestMixin支持内存数据库中的 H2。因此我添加了

testCompile 'org.grails:grails-datastore-test-support:4.0.5.RELEASE' 

给我的 build.gradle .但是当我添加 HibernateTestMixin我得到以下异常。

请您参考如下方法:

它应该可以正常工作 - 此示例使用 grails 3.0.1。 http://grails.github.io/grails-doc/3.0.1/guide/testing.html#unitTestingDomains

我猜使用 @TestFor 注释可能会为您解决问题。它将根据您正在测试的内容设置所需的任何 mixin。这是我的工作示例，位于

/src/test/groovy/grails3test/TeamSpec.groovy:

package grails3test 
 
import grails.test.mixin.TestFor 
import spock.lang.Specification 
 
/** 
 * See the API for {@link grails.test.mixin.domain.DomainClassUnitTestMixin} for usage instructions 
 */ 
@TestFor(Team) 
class TeamSpec extends Specification { 
 
    def setup() { 
        Team t = new Team(name: 'alphabravo') 
        t.save() 
    } 
 
    def cleanup() { 
    } 
 
    void "test something"() { 
        expect: 
        Team.findByName('alphabravo') != null 
    } 
}
