java - Spock mock - 设置和获取参数

Question

我在我的项目中使用 atlassian 的 maven，并希望在 spock 框架中实现测试。我对来自 Maven 的 Mock 类有问题(例如类 Issue - 它有一些私有(private)值，如 key 或 summary 并且没有像 setKey 和 setSummary 这样的方法。

我想要 Mock() Issue 对象，设置一些值然后获取它(有 getKey() 和 getSummary()).

我的代码如下:

class WriterSpec extends Specification {

    def returnValue() {
        given:
            Issue g = Mock(key: "exampleKey")
            String response = g.getKey()
        expect:
            response == "exampleKey"
    }
}

如果我尝试从 IDE 运行测试，则会出现错误(Java 类中的 Issue 对象没有问题，只是在 groovy 中):

如果我尝试从控制台运行测试(通过使用 atlas-mvn clean test):

我做了一些研究，但没有帮助。我不知道什么是问题以及为什么它不起作用。我应该怎么做才能修复它？

以下是仅测试 returnIssueKeyWithPrefix 的方法:

import spock.lang.Specification

class LolSpec extends Specification {

    def 'whatever'() {
        given:
        def prefixer = new Prefixer()
        def issue = Mock(Issue) {
            getKey() >> '1234'
        }

        when:
        def withPrefix = prefixer.returnIssueKeyWithPrefix(issue)

        then:
        withPrefix == 'prefix1234'
    }
}

class Issue {
    String getKey() {
        throw new UnsupportedOperationException('No!')
    }
}

class Prefixer {
    String returnIssueKeyWithPrefix(Issue issue) {
        return "prefix${issue.key}"
    }
}
