Grails單元測試帶有命令對象的方法

Question

我的單元測試有問題。 這是我的單元測試：

void "Test the update action performs an update on a valid domain instance"() {
    given:
        def aclServiceMock = mockFor(AclService)
        aclServiceMock.demand.updateRolePermissions { Role role, Map, roleMap, List permissions -> return true }
        controller.aclService = aclServiceMock.createMock()

        def roleInstance = setupRoleController()

        mockCommandObject RoleCommand
        RoleCommand cmd = new RoleCommand(
            authority: roleInstance?.authority,
            description: roleInstance?.description
        )

    when:"A valid domain instance is passed to the update action"
        controller.update(roleInstance, cmd)

    then:"A redirect is issued to the show action"
        response.redirectedUrl == "/role/index"
        flash.message != null
        flash.error == null
}

這是我從終端獲得的結果：

| Failure:  Test the update action performs an update on a valid domain instance(ph.gov.doe.core.acl.RoleControllerSpec)
|  Condition not satisfied:
flash.message != null
|     |       |
[:]   null    false
    at ph.gov.doe.core.acl.RoleControllerSpec.Test the update action performs an update on a valid domain instance(RoleControllerSpec.groovy:222)

我似乎無法弄清楚為什么我對特定方法的單元測試一直失敗。 也許我的Command Object模擬是關鍵？ 提前致謝。

編輯：條件應該是'response.redirectedUrl ==“ / role / index”'，我只是復制了錯誤的消息，原因是我當時對代碼不滿意。

編輯：這是控制器方法：

def update(Role roleInstance, RoleCommand roleCommand) {
    Map roleMap = [:]
    ArrayList collectPermission = [], getPermissions = [], roleList = []
    def savedRoleInstance

    /** collect selected permission into arraylist */
    collectPermission.addAll(params?.selectedPermission ?: [])
    getPermissions = Permission.findAllByIdInList(collectPermission)

    def roleEditInstance = Role.get(params?.roleId)

    /** Set data for validation of Role */
    roleCommand.with {
        id          = roleEditInstance?.id
        authority   = params?.authority
        description = params?.description
    }

    roleCommand.validate()        

    /** Check if the set of permission already exists */
    roleList = RolePermission.findAllByPermissionInListAndRoleNotEqual(getPermissions, Role.findByAuthority('ROLE_SUPERADMIN'))?.role

    def duplicateRolePermission = roleList.find { r -> r.getAuthorities().sort { it?.id } == getPermissions.sort { it?.id }  && r != roleEditInstance }

    if (collectPermission.isEmpty()) {
        flash.error = message(code: 'role.permissions.blank', args: [message(code: 'role.label', default: params?.authority)])
        respond roleInstance, model:[roleList: Role.list(), permissionList: Permission.findAllByAuthorityNotEqual('PERM_DASHBOARD_VIEW'), inheritPermission: params?.inheritPermission, selectedPermission: getPermissions], view: "edit"            
    } else if (roleCommand.hasErrors() || duplicateRolePermission != null) {
        bindData(roleCommand, roleInstance)

        if(duplicateRolePermission != null){
            flash.error = message(code: 'role.permissions.unique', args: [message(code: 'role.label', default: getPermissions?.description)])
        }

        respond roleCommand.errors, model:[roleInstance: roleCommand,roleList: Role.list(), permissionList: Permission.findAllByAuthorityNotEqual('PERM_DASHBOARD_VIEW'), inheritPermission: params?.inheritPermission, selectedPermission: getPermissions, roleId: roleEditInstance?.id], view: "edit"
    } else {
        /** Save the Role */
        roleMap = [authority: params?.authority, description: params?.description]
        def savedRole = aclService.updateRolePermissions(roleEditInstance, roleMap, getPermissions)

        if (currentAccount) {
           auditLogService.logEvent(currentAccount.emailAddress, "UPDATE_ROLE_SUCCESS", "Successfully updated role details.", true) 
        }

        flash.message = message(code: 'role.updated.message', args: [message(code: 'role.label', default: savedRole?.authority)])
        flash.id = savedRole?.id
        redirect action: 'view', params:[id: savedRole?.id]
    }
}

似乎您要測試的應用程序可能設計得更好。 許多邏輯可以從控制器轉移到服務（ 關注點分離原則）。

同樣，您的測試看起來像集成測試而不是單元測試。 因此，我建議您熟悉基於交互的測試 。

祝好運！
