从Grails 2.3迁移到2.4后，grails生成的控制器测试失败

Question

当我使用grails 2.4.4生成控制器和相关的单元测试类时，即使我在populateValidParams（）中设置了必要的测试数据后，我也会遇到测试失败。我可以通过将 model.personInstance！= null （对于Person类）更改为 model.person！= null 来修复大多数失败。我很惊讶这是必要的，但至少它是有效的。

其他测试失败发生在保存，更新和删除相关测试上，并因 response.redirectUrl 为空。通过使用调试器逐步执行它，似乎 request.withFormat 闭包正在访问通配符语句而不是 form / multipartForm 块。我认为生成的单元测试中的 request.contentType = FORM_CONTENT_TYPE 应该导致代码命中代码的 form / multipartForm 部分。

这是我正在为只需要firstName和lastName字段的Person域类测试的代码...

域类：

package org.crspta.gohomenotes
import groovy.transform.EqualsAndHashCode

@EqualsAndHashCode()
class Person implements Serializable {

User user

Date dateCreated
Date lastUpdated

String firstName
String middleName
String lastName
String nickname
String emailAddress
String cellPhone
String homePhone
String workPhone

static constraints = {
    firstName nullable: false
    middleName nullable: true
    lastName nullable: false
    nickname nullable: true
    emailAddress nullable: true, email: true
    cellPhone nullable: true
    homePhone nullable: true
    workPhone nullable: true
    user nullable: true
}

@Override
public String toString() {
    return "${name}"
}  

public String getName() {
    def name = "$lastName, $firstName"
    if (nickname) {
        name += " ($nickname)"
    }
    return name
}
}

PersonControllerSpec：

@TestFor(PersonController)
@Mock(Person)
class PersonControllerSpec extends Specification {

def populateValidParams(params) {
    assert params != null
    params["firstName"] = 'Firstname'
    params["lastName"] = 'Lastname'
}

由于response.redirectUrl为空而失败的单元测试方法。

    void "Test the save action correctly persists an instance"() {

    when:"The save action is executed with an invalid instance"
        request.contentType = FORM_CONTENT_TYPE
        request.method = 'POST'
        def person = new Person()
        person.validate()
        controller.save(person)

    then:"The create view is rendered again with the correct model"
        model.person != null
        view == 'create'

    when:"The save action is executed with a valid instance"
        response.reset()
        populateValidParams(params)
        person = new Person(params)

        controller.save(person)

    then:"A redirect is issued to the show action"
        response.redirectedUrl == '/person/show/1'
        controller.flash.message != null
        Person.count() == 1
}

PersonController save（）方法：

    @Transactional
def save(Person personInstance) {
    if (personInstance == null) {
        notFound()
        return
    }

    if (personInstance.hasErrors()) {
        respond personInstance.errors, view:'create'
        return
    }

    personInstance.save flush:true

    request.withFormat {
        form multipartForm {
            flash.message = message(code: 'default.created.message', args: [message(code: 'person.label', default: 'Person'), personInstance.id])
            redirect personInstance
        }
        '*' { respond personInstance, [status: CREATED] }
    }
}

特定错误消息：

response.redirectedUrl == '/person/show/1'
