Grails单元测试模拟域类在其控制器内

Question

我是grails新手。在我的web应用中，我使用spock进行单元测试。

我已经使用了可搜索插件的搜索功能。

在我的控制器中，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'
    }

但是我不能嘲笑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]]

请任何人帮助我解决这个问题。

我猜你正在使用可搜索的插件。如果您想测试搜索功能，请编写一个IntegrationSpec。要在控制器中模拟Domainclass的搜索调用，最好将其包装在一个服务方法中，并模拟出服务。

我认为您不希望在这里测试Question域的约束。

试试这样写:

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'
}

你需要用一个封装了Question.search()命令的方法来创建Service，并在你的控制器搜索方法中使用这个服务方法。

像这样:

class QuestionService {
   def search(String query, def params) {
       Question.search(query, params)
   }
}

你的控制器搜索方法:

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。
