unit-testing - Grails 单元测试在其 Controller 中模拟域类

Question

我是 grails 的新手。在我的 Web 应用程序中，我使用 spock 进行单元测试。

我使用了可搜索插件来实现搜索功能。

在我的 Controller 搜索方法定义为:

def search(SearchQueryCommand searchQueryCommand) {
        def question
        if (!searchQueryCommand.q?.trim() && !searchQueryCommand.tag?.trim() && !searchQueryCommand.name?.trim()) {
            params.sort='sortableTitle'
            params.order='desc'
            question = Question.search(MessageStatusEnum.ACTIVE.getType().toString(), params)
        }
    render(view: "include_questionlist", model: [questionList: question.results, totalSize:question.total , max:params.max?:'Constants.PAGINATION_DEFAULT_MAX', pagination:true ,questionDescription:true])
}

在测试时我已经定义了

void "action search questions : search with blank search query" () {

        setup:
        controller.params.q=""
        mockForConstraintsTests(Question)
        mockDomain(User)
        def question1 =new Question(title:'demo1', owner:new User(username:"Jini").save())
        def question2 =new Question(title:'demo2', owner:new User(username:"Jini").save())

        Question.search() >> [question1,question2]
        when:
        controller.search()

        then:
        view == '/question/include_questionlist'

    }

但我不能模拟 Question.search() 方法。

错误消息接收为

Failure:  action search questions : search with blank search query(com.orb.question.QuestionControllerSpec)
|  groovy.lang.MissingMethodException: No signature of method: com.orb.question.Question.search() is applicable for argument types: (java.lang.String, org.codehaus.groovy.grails.web.servlet.mvc.GrailsParameterMap) values: [1992, [q:, sort:sortableTitle, order:desc]]

请任何人帮我解决这个问题。

提前致谢。

我猜您正在使用可搜索插件。
如果您想测试搜索功能，请编写一个 IntegrationSpec。
要在 Controller 中模拟域类的搜索调用，最好将其包装在服务方法中并模拟出服务。

而且我认为您不想在这里测试 Question 域的约束。

尝试这样的事情:

void "action search questions : search with blank search query" () {

    setup:
    params.q=""
    mockDomain(Question)
    mockDomain(User)
    def question1 =new Question(title:'demo1', owner:new User(username:"Jini").save())
    def question2 =new Question(title:'demo2', owner:new User(username:"Jini").save())

    QuestionService fakeQuestionService = Mock()
    fakeQuestionService.search(_,_) >> [question1,question2]
    controller.questionService = fakeQuestionService

    when:
    controller.search()

    then:
    view == '/question/include_questionlist'

}

您需要使用包装 Question.search() 命令的方法创建服务，并在 Controller 搜索方法中使用此服务方法。

类似的东西:

class QuestionService {

   def search(String query, def params) {

       Question.search(query, params)
   }

}

您的 Controller 搜索方法:

def search(SearchQueryCommand searchQueryCommand) {
    def question

    if (!searchQueryCommand.q?.trim() && !searchQueryCommand.tag?.trim() && !searchQueryCommand.name?.trim()) {
        params.sort='sortableTitle'
        params.order='desc'
        question = questionService.search(MessageStatusEnum.ACTIVE.getType().toString(), params)
    }
    render(view: "include_questionlist", model: [questionList: question.results, totalSize:question.total , max:params.max?:'Constants.PAGINATION_DEFAULT_MAX', pagination:true ,questionDescription:true])
}

我希望你明白我的意思。
