第一次在这里发帖。感谢您抽出宝贵时间来审核这个问题。
由于标题表明问题与flex应用程序的服务层有关。特别是在测试用例类中。要调用服务，用户必须首先通过基于html / CF的页面进行身份验证。一旦完成并且身份验证已经发生，用户将被定向到嵌入了flex应用程序的html页面。一旦经过身份验证，服务器端CF代码就会将cookie写入用户计算机。然后，flex应用程序将读取此cookie，并且Flex应用程序需要调用CF服务。
问题是：如何在flex app中的服务类的测试用例类中处理它？基本上需要执行以下步骤：使用一些帐户数据来访问服务器并进行身份验证，然后需要编写cookie（它已经存在），然后测试用例需要从cookie中获取会话ID并通过它是测试用例中的服务调用。对于测试用例类来说，这一切似乎都太过分了。
那么，这种事情通常是如何处理的。从我收集的内容来看，Web服务调用通常需要像这样的会话ID。
非常感谢任何想法，意见，建议等。
感谢您抽出时间和任何可以提供的信息。

将在集成测试中测试cookie和实际服务调用。 Yoyou认为这些位不适合单元测试是正确的。
我喜欢做的是一个很好的委托（假设您的集成点还没有表达接口）并创建实现我选择的接口的测试委托。 cookie将被“检索”，并且它总是对您的测试有效。如果您需要将其设置为false，请创建另一个测试委托并将其作为依赖项提供。
Mockolate可以走很长的路，但建立坚固的模拟是关键。
所以这是一个例子。它没有直接回答你的问题，但我认为它代表了一些相同的问题，因此可能会帮助你解决特定情况。
我正在使用第三方库来处理此应用中的SQL操作。该库有一个名为SQLRunner的核心类。实际上，这个类没有接口（这会使事情变得容易一些）。我有两个选择。
碰巧，我做了两件事，但出于多种原因更喜欢第二种方法。我能够完全定义第三方库的API和功能。这太棒了。我实际上没有更改API，但是如果你不喜欢它如何命名方法......不用担心，改变它。它还允许我表达一个界面！我最初这样做是因为我想使用Mockolate来模拟其用法。它也可以用来创建我自己的测试模拟，它具有更强大的功能并且更加清晰。所以这是服务：
public class SQLTaskService extends Actor implements ITaskService
{
[Inject]
public var sqlRunner:ISQLRunnerDelegate;
[Inject]
public var statusListModel:StatusListModel;
[Inject]
public var taskListModel:TaskListModel;
public function loadAllTasks():void
{
statusListModel.removeAllTasks();
sqlRunner.execute(LOAD_ALL_TASKS_SQL, null, loadAllTasksResultHandler, Task, databaseErrorHandler);
}
private function loadAllTasksResultHandler(result:SQLResult):void
{
for each(var task:Task in result.data)
{
var taskStatus:Status = statusListModel.getStatusFromId(task.statusId);
statusListModel.addTaskToStatus(task, taskStatus);
taskListModel.addTask(task);
}
}
public function loadTaskById(id:int):void
{
sqlRunner.execute(LOAD_TASK_SQL, {taskId:id}, loadTaskResultHandler, Task);
}
private function loadTaskResultHandler(result:SQLResult):void
{
var task:Task = result.data[0] as Task;
var taskStatus:Status = statusListModel.getStatusFromId(task.statusId);
task = taskListModel.updateTask(task);
statusListModel.addTaskToStatus(task, taskStatus);
}
public function save(task:Task):void
{
var params:Object = task.toParamObject();
sqlRunner.executeModify(Vector.<QueuedStatement>(
[new QueuedStatement(SAVE_TASK_SQL, params)]), saveTaskResultHandler, databaseErrorHandler);
}
private function saveTaskResultHandler(results:Vector.<SQLResult>):void
{
var result:SQLResult = results[0];
if (result.rowsAffected > 0)
{
var id:Number = result.lastInsertRowID;
loadTaskById(id);
}
}
public function deleteTask(task:Task):void
{
sqlRunner.executeModify(Vector.<QueuedStatement>([new QueuedStatement(DELETE_TASK_SQL, {taskId:task.taskId})]),
deleteTaskResult, databaseErrorHandler);
}
private function deleteTaskResult(results:Vector.<SQLResult>):void
{
//pass
}
private function databaseErrorHandler(error:SQLError):void
{
dispatch(new DatabaseErrorHandlerEvent(error.message));
}

}
你可以看到它具有委托依赖：
/**
* This is a delegate for the SQLRunner class that allows us to utilize an interface
* for the purposes of creating mocks. The actual SQLRunner class does not express
* an interface. This approach also allows us to encapsulate the usage of a 3rd party
* library into this single delegate.
*
* <p>An alternative would be to fork and modify the original library, which would
* definitely be a viable option and would help others in the future.</p>
*/
public class SQLRunnerDelegate implements ISQLRunnerDelegate
{
private var sqlRunner:SQLRunner;
public function SQLRunnerDelegate(dataBaseFile:File, maxPoolSize:int = 5)
{
sqlRunner = new SQLRunner(dataBaseFile, maxPoolSize);
}
public function get numConnections():int
{
return sqlRunner.numConnections;
}
public function get connectionErrorHandler():Function
{
return sqlRunner.connectionErrorHandler;
}
public function set connectionErrorHandler(value:Function):void
{
sqlRunner.connectionErrorHandler = value;
}
public function execute(sql:String, parameters:Object, handler:Function, itemClass:Class = null, errorHandler:Function = null):void
{
sqlRunner.execute(sql, parameters, handler, itemClass, errorHandler);
}
public function executeModify(statementBatch:Vector.<QueuedStatement>, resultHandler:Function, errorHandler:Function, progressHandler:Function = null):void
{
sqlRunner.executeModify(statementBatch, resultHandler, errorHandler, progressHandler);
}
public function close(resultHandler:Function, errorHandler:Function = null):void
{
sqlRunner.close(resultHandler, errorHandler);
}
}
结果非常好。现在我的应用程序与第三方库有一个很小的集成点。大赢。我还可以制作健壮的模拟，而无需处理文件系统或第三方库的任何其他奇怪的依赖：
/**
* This is a more robust mock for the SQLRunnerDelegate to test for
* side effects that occur when methods are called on SQLTaskService
*/
public class MockTaskSQLRunnerDelegate extends MockSQLRunnerDelegateBase implements ISQLRunnerDelegate
{
public function execute(sql:String, parameters:Object, handler:Function, itemClass:Class = null, errorHandler:Function = null):void
{
lastStatementExecuted = sql;
allStatementsExecuted.push(lastStatementExecuted);
parametersSent = parameters;
switch (sql)
{
case SQLTaskService.LOAD_ALL_TASKS_SQL:
handler.call(null, loadTask());
break;
case SQLTaskService.LOAD_TASK_SQL:
handler.call(null, loadTask());
break;
default:
break;
}
}
private function loadTask():SQLResult
{
var task:Task = new Task();
var data:Array = [task];
var result:SQLResult = new SQLResult(data);
task.taskId = 1;
task.statusId = 1;
return result;
}
public function executeModify(statementBatch:Vector.<QueuedStatement>, resultHandler:Function, errorHandler:Function, progressHandler:Function = null):void
{
lastStatementExecuted = statementBatch[0].statementText;
allStatementsExecuted.push(lastStatementExecuted);
parametersSent = statementBatch[0].parameters;
switch (lastStatementExecuted)
{
case SQLTaskService.SAVE_TASK_SQL:
resultHandler.call(null, saveTask());
break;
}
}
private function saveTask():Vector.<SQLResult>
{
var task:Task = new Task();
var result:SQLResult = new SQLResult([task], 1, true, 1);
var results:Vector.<SQLResult> = new Vector.<SQLResult>();
task.taskId = task.statusId = 1;
results.push(result);
return results;
}
public function get numConnections():int
{
return 0;
}
public function get connectionErrorHandler():Function
{
return null;
}
public function set connectionErrorHandler(value:Function):void
{
}
public function close(resultHandler:Function, errorHandler:Function = null):void
{
}
}
我从这笔交易中得到了一个不错的测试套件：

{
private var taskService:SQLTaskService;

{
taskService = new SQLTaskService();
taskService.statusListModel = new StatusListModel();
taskService.taskListModel = new TaskListModel();

prepareMockolates();
}

Async.proceedOnEvent(this, prepare(ISQLRunnerDelegate), Event.COMPLETE);

附注：我想在此指出的是没有一个单一的异步测试。很少需要运行单元测试异步。有些边缘情况你可能真的需要，但它们是例外。
