从黄瓜功能文件更新 json 有效负载的最佳方法

Question

I have a complex Json which acts like a input to a webservice. I have created necessary POJO classes for it and I am using Jackson object mapper in my code.

What could be the best way to update the partial Json data from cucumber data tables?

Thanks in advance !!!

Original Json:

{
    "accNum": "Dummy_Account",
    "customerData": {
        "customerName": "Dummy_Name",
        "customerAddress": "Dummy_Address"
        
    },
    "accountData": {
        "cashAccountRef": "Dummy",
        "acntCrncy": "EUR",
        "foreignCurrencyAccounts": [
            {
                "foreignCurrency": "USD",
                "foreignCrncyAcntRef": "Dummy2"
                
            }
        ]
    }
    ]
}

Cucumber Feature File

Given Prepare Input request for below data
      | accNum                                                 | 12345   |
      | customerData.customerName                              | New Name|
      | accountData.foreignCurrencyAccounts[0].foreignCurrency | EUR     |

Final Json to be passed as input

{
    "accNum": "12345",
    "customerData": {
        "customerName": "New Name",
        "customerAddress": "Dummy_Address"
        
    },
    "accountData": {
        "cashAccountRef": "Dummy",
        "acntCrncy": "EUR",
        "foreignCurrencyAccounts": [
            {
                "foreignCurrency": "EUR",
                "foreignCrncyAcntRef": "Dummy2"
                
            }
        ]
    }
    ]
}

Answer 1

If you're using POJO then stick to this approach. Using setter to update value of the key, of course you can use builder style for setter to make it more easier to read.

Answer 2

I found only this way

((ObjectNode) parent).putRawValue(valueOfKeyToModify, new RawValue(newValue));

The problem arises when there are many identical keys. And then you need to read the tree and go around it until it matches exactly the key that needs to be changed.

And if you need to lay string, then you must also specify quotes, since it lays the raw value
