覆盖日期在Grails中进行测试 [英] Overriding dateCreated for testing in Grails

问题描述

有没有什么办法可以覆盖我的域类中的 dateCreated 字段的值而不关闭自动时间戳？

Is there any way I can override the value of dateCreated field in my domain class without turning off auto timestamping?

我需要测试控制器，并且必须提供具体创建日期的特定域对象，但GORM似乎覆盖了我提供的值。

I need to test controller and I have to provide specific domain objects with specific creation date but GORM seems to override values I provide.

我的课程如下所示：

My classes look like this:

class Message {

    String content
    String title
    User author

    Date dateCreated
    Date lastUpdated

    static hasMany = [comments : Comment]

    static constraints = {
        content blank: false
        author nullable: false
        title nullable: false, blank: false
    }

    static mapping = {
        tablePerHierarchy false
        tablePerSubclass true
        content type: "text"
        sort dateCreated: 'desc'
    }
}

class BlogMessage extends Message{

    static belongsTo = [blog : Blog]

    static constraints = {
        blog nullable: false
    }

}

我使用控制台来缩短事情。我写的时候遇到的问题是，当我写作时：

I'm using console to shorten things up. The problem which I encountered with Victor's approach is, when I write:

Date someValidDate = new Date() - (20*365)

BlogMessage.metaClass.setDateCreated = {
            Date d ->            
            delegate.@dateCreated = someValidDate
}

我得到以下异常：

groovy.lang.MissingFieldException: No such field: dateCreated for class: pl.net.yuri.league.blog.BlogMessage

当我尝试时

Message.metaClass.setDateCreated = {
                Date d ->            
                delegate.@dateCreated = someValidDate
}

脚本很顺利，但不幸的是 dateCreated 未被更改。

Script goes well, but unfortunately dateCreated is not being altered.

推荐答案

我遇到类似的问题，并且能够通过

I was having a similar issue, and was able to overwrite dateCreated for my domain (in a Quartz Job test, so no @TestFor annotation on the Spec, Grails 2.1.0) by

$ b $覆盖我的域的dateCreated（在Quartz Job测试中，所以在Spec，Grails 2.1.0上没有@TestFor注解） b
• 使用BuildTestData插件（我们经常使用它，它真是太棒了）


• 使用save（flush：true）双击域实例

• Using the BuildTestData plugin (which we use regularly anyway, it is fantastic)
• Double-tapping the domain instance with save(flush:true)

作为参考，我的测试：

For reference, my test:

import grails.buildtestdata.mixin.Build
import spock.lang.Specification
import groovy.time.TimeCategory

@Build([MyDomain])
class MyJobSpec extends Specification {

    MyJob job

    def setup() {
        job = new MyJob()
    }

    void "test execute fires my service"() {
        given: 'mock service'
            MyService myService = Mock()
            job.myService = myService

        and: 'the domains required to fire the job'
            Date fortyMinutesAgo
            use(TimeCategory) {
                fortyMinutesAgo = 40.minutes.ago
            }

            MyDomain myDomain = MyDomain.build(stringProperty: 'value')
            myDomain.save(flush: true) // save once, let it write dateCreated as it pleases
            myDomain.dateCreated = fortyMinutesAgo
            myDomain.save(flush: true) // on the double tap we can now persist dateCreated changes

        when: 'job is executed'
            job.execute()

        then: 'my service should be called'
            1 * myService.someMethod()
    }
}
