Actionscript 3 TextInput文本更改的Flexunit测试，两个绑定失败

我正在尝试为flex中的视图编写一个单元测试。TextInput，

reportName

和属性，

\u parameters

之间存在双向绑定。当我运行代码时，绑定工作正常，但测试失败。下面是许多以类似方式失败的测试之一。测试失败，并显示以下消息：

Error: Expected: "newName"
but: was "defaultTitle"

    <fx:Script>
        <![CDATA[
            import events.events.UpdatePointRadiusReportModalParametersEvent;

            public function set parameters(parameters:LocationAnalysisParameters):void

parameters\u changeHandler（）

中的跟踪消息显示以下内容：

parameters_changeHandler
_parameters.reportName defaultTitle
reportName.text newName

    <fx:Script>
        <![CDATA[
            import events.events.UpdatePointRadiusReportModalParametersEvent;
            import model.LocationAnalysisParameters;

            [Bindable]
            internal var _parameters:LocationAnalysisParameters;

            public function set parameters(parameters:LocationAnalysisParameters):void
            {
                this._parameters = parameters;
            }

            public function get parameters():LocationAnalysisParameters
            {
                return _parameters;
            }

            protected function parameters_changeHandler():void

                trace('_parameters.reportName', _parameters.reportName);
                trace('reportName.text', reportName.text);
                dispatchEvent(new UpdatePointRadiusReportModalParametersEvent(_parameters));
            }
        ]]>
    </fx:Script>

    <s:VGroup>
        <s:Label id="reportNameLabel"
            styleName="toolStyle"

因此，文本输入，

reportName

，正在正确更新，但我在测试中设置文本的方式是取消绑定，至少我认为这是问题所在

    <fx:Script>
        <![CDATA[
            import events.events.UpdatePointRadiusReportModalParametersEvent;
            import model.LocationAnalysisParameters;

            [Bindable]
            internal var _parameters:LocationAnalysisParameters;

            public function set parameters(parameters:LocationAnalysisParameters):void
            {
                this._parameters = parameters;
            }

            public function get parameters():LocationAnalysisParameters
            {
                return _parameters;
            }

            protected function parameters_changeHandler():void
            {
                trace('parameters_changeHandler');
                trace('_parameters.reportName', _parameters.reportName);
                trace('reportName.text', reportName.text);
                dispatchEvent(new UpdatePointRadiusReportModalParametersEvent(_parameters));
            }
        ]]>
    </fx:Script>

    <s:VGroup>
        <s:Label id="reportNameLabel"
            styleName="toolStyle"
            text="Report Name:"/>
        <s:TextInput id="reportName"
            width="100%"
            maxChars="50"
            minWidth="200"
            styleName="toolStyle"
            text="{_parameters.reportName}"
            change="parameters_changeHandler()"
            restrict="a-zA-Z0-9 \-_"/>
    </s:VGroup>

如何维护这两个绑定并仍然更新值？有没有其他方法可以模拟用户输入数据

            public function set parameters(parameters:LocationAnalysisParameters):void
            {
                this._parameters = parameters;
            }

            public function get parameters():LocationAnalysisParameters
            {
                return _parameters;
            }

            protected function parameters_changeHandler():void
            {
                trace('parameters_changeHandler');
                trace('_parameters.reportName', _parameters.reportName);
                trace('reportName.text', reportName.text);
                dispatchEvent(new UpdatePointRadiusReportModalParametersEvent(_parameters));
            }
        ]]>

我想我只是需要考虑一下。我的测试失败的原因是双向绑定仅在您将它们指定为双向绑定时才起双向绑定的作用

    <fx:Script>
        <![CDATA[
            import events.events.UpdatePointRadiusReportModalParametersEvent;
            import model.LocationAnalysisParameters;

            internal var _parameters:LocationAnalysisParameters;

            public function set parameters(parameters:LocationAnalysisParameters):void
            {
                this._parameters = parameters;
            }

            public function get parameters():LocationAnalysisParameters
            {
                return _parameters;
            }

            protected function parameters_changeHandler():void
            {
                trace('parameters_changeHandler');
                trace('_parameters.reportName', _parameters.reportName);
                trace('reportName.text', reportName.text);
                dispatchEvent(new UpdatePointRadiusReportModalParametersEvent(_parameters));
            }
        ]]>
