我正在尝试测试一个简单的服务方法。该方法主要只返回一个条件查询的结果,我想测试它是否返回一个结果(取决于查询的内容)。
问题是,我不知道如何正确正确地进行相应的测试。我试图通过 spock 来完成它,但是用任何其他测试方式做同样的事情也失败了。
谁能告诉我如何修改测试以使其适用于手头的任务?
(顺便说一句,如果可能的话,我想将其保留为单元测试。)
事件服务方法
public HashSet<Event> listEventsForDate(Date date, int offset, int max) {
date.clearTime()
def c = Event.createCriteria()
def results = c {
and {
le("startDate", date+1) // starts tonight at midnight or prior?
ge("endDate", date) // ends today or later?
}
maxResults(max)
order("startDate", "desc")
}
return results
}
Spock 规范
package myapp
import grails.plugin.spock.*
import spock.lang.*
class EventServiceSpec extends Specification {
def event
def eventService = new EventService()
def setup() {
event = new Event()
event.publisher = Mock(User)
event.title = 'et'
event.urlTitle = 'ut'
event.details = 'details'
event.location = 'location'
event.startDate = new Date(2010,11,20, 9, 0)
event.endDate = new Date(2011, 3, 7,18, 0)
}
def "list the Events of a specific date"() {
given: "An event ranging over multiple days"
when: "I look up a date for its respective events"
def results = eventService.listEventsForDate(searchDate, 0, 100)
then: "The event is found or not - depending on the requested date"
numberOfResults == results.size()
where:
searchDate | numberOfResults
new Date(2010,10,19) | 0 // one day before startDate
new Date(2010,10,20) | 1 // at startDate
new Date(2010,10,21) | 1 // one day after startDate
new Date(2011, 1, 1) | 1 // someday during the event range
new Date(2011, 3, 6) | 1 // one day before endDate
new Date(2011, 3, 7) | 1 // at endDate
new Date(2011, 3, 8) | 0 // one day after endDate
}
}
