robotframework - 如何从变化的索引中获取数据

Question

我有这个布局的JSON对象：

{
    "events": [{
            "type": "page",
            "sessionId": "d9e3643a-5126-4ee4-bcc8-5fa1b4fdf52b",
            "changes": {
                "changes": [{
                            "model": {
                            "styles": ["bold"],
                            "name": "TextItem",                         
                            },
                            "type": "update",
                            "key": "1"
                            }, {
                            "model": {
                            "styles": [],
                            "name": "TextItem",
                            "plainText": "Skoda Octavia",
                            },
                            "type": "textitem",
                            "properties": {}
                            ,
                            "type": "update",
                            "key": "2"
                            }, {
                            "model": {
                            "questionText": "Bouwjaar",
                            "validations": [{
                                    "message": "Dit veld is verplicht",                     
                                }, {
                                    "message": "Voer een geldig bouwjaar op.",
                                    }
                                }
                            ],
                            **"messages": [{
                                    "text": "Dit veld is verplicht",
                                    "type": "ERROR"
                                }**
                            ],
                            "name": "Motorrijtuig.Bouwjaar"
                        },
                        "type": "update",
                        "key": "3"
    }}]}]}

我想验证带有questionText ='Bouwjaar'的模型有message.text ='Dit veld is verplicht'

解决方案可能是： $ {test} =评估| '$ {JSON ['events'] [0] ['changes'] ['changes'] [2] ['model'] ['messages'] [0] ['text']}'=='Dit veld是verplicht'

但是有了新的更新，索引可能会被更改，我的测试将失败。

我现在的解决方案是： 对于每个modelobject - ＆gt;检查questionText是否在modelobject中 - ＆gt;是 - ＆gt;检查questionText = Bouwjaar - ＆gt;是 - ＆gt;检查消息 在我的jsonobject中有14个modelobjects

是否有更简单的方法来检查message.text，而不是de indexcontext？
