unit-testing - grails 单元测试 spock 问题

Question

我是 grails 新手。 我只是搭建一个域类员工，如下所示

class Employee {

    String firstName
    String lastName

    static constraints = {
    }
}

我正在尝试使用 spock 在 EmployeeController 中编写一个关于列表操作的单元测试。 Controller 如下所示

class EmployeeController {

    static allowedMethods = [save: "POST", update: "POST", delete: "POST"]

    def index() {
        redirect(action: "list", params: params)
    }

    def list(Integer max) {
        params.max = Math.min(max ?: 10,100)
        [employeeInstanceList: Employee.list(params), employeeInstanceTotal: Employee.count()]
    }
}

然后我编写了下面给出的测试用例

import grails.test.mixin.TestFor
import spock.lang.Specification

@TestFor(EmployeeController)
class EmployeeControllerUnitSpec extends Specification {

    def 'test index'() {
        when:
        controller.index()

        then:
        // httpcode ? 200
        //println response (GrailsMockHttpServletResponse)
        response.redirectedUrl == '/employee/list'
    }

    def 'test list empty'() {
        when:
        controller.list( 10 )
        // Employee.list()

        then:
        model.employeeInstanceTotal == 0;

    }
}

这里索引的测试用例工作正常，但测试列表空在控制台中呈现一些错误。 控制台错误描述为

| Running 2 spock tests... 2 of 2
| Failure:  test list empty(com.test.EmployeeControllerUnitSpec)
|  groovy.lang.MissingMethodException: No signature of method: com.test.Employee.list() is applicable for argument types: () values: []
Possible solutions: list(), list(java.util.Map), last(), last(java.lang.String), last(java.util.Map), first()
    at com.test.EmployeeController.list(EmployeeController.groovy:15)
    at com.test.EmployeeControllerUnitSpec.test list empty(EmployeeControllerUnitSpec.groovy:21)
| Completed 2 spock tests, 1 failed in 3231ms
| Tests FAILED  - view reports in /mnt/hdd2/home/T-2060/workspace/testing/target/test-reports

谁能建议一下，如何解决这个问题

提前谢谢

单元测试环境在模拟之前不会提供可用的域。

使用@Mock(Employee)并在Employee中设置测试数据来测试list()操作。
