Grails3单元测试中GORM addTo方法的使用

Question

我正在将Grails2中的一系列单元测试升级到Grails3，并且在使用GORM动态方法的域测试中遇到了问题--特别是addTo{myHasMany}方法。

给定以下域对象

class Contact {
  static hasMany = [ emails: ContactEmail ]

  void addEmail(ContactEmail newEmail) {

    //Clear the existing primary flag if the new email is marked primary
    if (newEmail.primaryEmail == true) {
        for (ContactEmail contactEmail in this.emails) {
            if (contactEmail.primaryEmail == true) {
                contactEmail.primaryEmail = false
            }
        }
    }

    //Implicitly set the primary flag on the new email if it is the first in the list
    if ((this.emails == null) || (this.emails.size() == 0)) {
        newEmail.primaryEmail = true
    }

    //Add the email to the contact
    this.addToEmails(newEmail)
  }

}

class ContactEmail {
  String email
  Boolean primaryEmail

  static belongsTo = [ contact: Contact ]
}

@TestMixin(DomainClassUnitTestMixin)
@TestFor(Contact)
class ContactSpec {

  def setup() {
  }

  def cleanup() {
  }

  @Unroll
  void "test Contact addEmail()"() {
    when:
    Contact contact = new Contact()
    ContactEmail contactEmail = new ContactEmail(email: "[e-mail]", primaryEmail: false)
    contact.addEmail(contactEmail)

    then:       
    /* DOC - The add email without any other emails should implicitly set the primary email */
    contact.primaryEmail.toString() == "[e-mail]"
  }
}

我尝试使用DomainClassUnitTestMixin和mockDomain（）方法模拟Contact实例，以生成带有GORM方法（或子集）的实例。

我已经尝试了使用基于Spock交互的测试支持的方法。

事实上，我已经尝试了几乎所有我能想到的组合来让这个工作没有任何运气。我重读了最新Grails规范中的测试部分。

在这里有什么方法可以让它保持一个单元测试吗？

我没有看到newemail在方法中的任何位置被初始化。因此，addtoEmails()失败，因为传递的参数为null。我认为您希望您的方法声明如下。

void addEmail(ContactEmail newEmail) {
//Clear the existing primary flag if the new email is marked primary
if (newEmail.primaryEmail == true) {
    for (ContactEmail contactEmail in this.emails) {
        if (contactEmail.primaryEmail == true) {
            contactEmail.primaryEmail = false
        }
    }
}

//Implicitly set the primary flag on the new email if it is the first in the list
if ((this.emails == null) || (this.emails.size() == 0)) {
    newEmail.primaryEmail = true
}

//Add the email to the contact
this.addToEmails(newEmail)
 }
