Json Groovy中的数字格式异常

我试图将销售税税率6.75与我的预期值6.75（字符串格式）进行比较。我编写了下面几行Groovy代码来实现这一点，但我遇到了数字格式异常，我无法找出问题所在

Groovy代码

def jsonSlurper = new JsonSlurper()
def parsedResponseJson=jsonSlurper.parseText(context.expand('${StandardFinance#Response}'))
def actualSalesTaxRate = parsedResponseJson.CustomerQuoteFinanceResponse.StandardFinanceResponse.Responses[0].StandardPaymentEngineFinanceResponse.paymentWithTaxes.financeItemizedTaxes.salesTax.taxParameters.rate
def actualSalesTaxRate = parsedResponseJson.CustomerQuoteFinanceResponse.StandardFinanceResponse.Responses[0].StandardPaymentEngineFinanceResponse.paymentWithTaxes.financeItemizedTaxes.salesTax.taxParameters.rate
log.info actualSalesTaxRate.size()
actualSalesTaxRate = Float.parseFloat(actualSalesTaxRate)
def expectedSalesTaxRate = "6.75"
log.info expectedSalesTaxRate.size()
expectedSalesTaxRate = Float.parseFloat(expectedSalesTaxRate)
assert expectedSalesTaxRate.toString() == actualSalesTaxRate.toString(),"FAIL --- Sales Tax Rate is different"

JSON响应

{
"CustomerQuoteFinanceResponse": {
    "StandardFinanceResponse": {
        "Responses": [{
            "StandardPaymentEngineFinanceResponse": {
                "class": ".APRNonCashCustomerQuote",
                "RequestID": "1",
                "term": "48",
                "financeSourceId": "F000CE",
                "paymentWithTaxes": {
                    "class": ".FinancePaymentWithTaxes",
                    "amountFinanced": "34523.48",
                    "monthlyPayment": "782.60",
                    "monthlyPaymentWithoutDealerAddOns": 782.6,
                    "financeItemizedTaxes": {
                        "salesTax": {
                            "taxParameters": {
                                "rate": "6.75"
                            },
                            "salesTaxAmount": "2322.61"
                        }
                    }
                }
            }
        }]
    }
}
}

您不必将其转换为数字，因为响应中的值是字符串

• 定义一个测试用例级自定义属性，比如

  EXPECTED\u TAX\u RATE

  ，并将值提供为

  6.75

• 在响应中，

  速率

  是一个字符串值
• 在这种特殊情况下，不需要创建额外的Groovy脚本测试步骤，只需检查/比较值，即remove步骤
• 相反，使用上述代码为rest请求测试步骤本身添加

  脚本断言

• 但是，需要读取响应时会有一些小的变化

下面是完整的

脚本断言

//Check the response is received
assert context.response, 'Response is empty or null'

//Read test case property for expected value as string; this way there is no need to edit the assertion; just change the property value
def expectedTaxRate = context.expand('${#TestCase#EXPECTED_TAX_RATE}')

def json = new groovy.json.JsonSlurper().parseText(context.response)

def actualTaxRate = json.CustomerQuoteFinanceResponse.StandardFinanceResponse.Responses[0].StandardPaymentEngineFinanceResponse.paymentWithTaxes.financeItemizedTaxes.salesTax.taxParameters.rate
log.info "Actual tax rate $actualSalesTaxRate"

//Now compare expected and actual
assert actualTaxRate == expectedTaxRate, 'Both tax rates are not matching'

您可能会遇到诸如“关于字符串值的问题。如何与数字进行比较。例如，

monthlyPaymentWithoutDealerAddOns

是否有数字而不是字符串。如何处理？”

这里，当一个测试用例级自定义属性被定义为

EXPECTED\u MONTHLY\u PATYMENT

，值被定义为

782.6

如上所述，可以在

脚本断言中阅读上述内容，如下所示

def expectedMonthlyPayment = context.expand('${#TestCase#EXPECTED_MONTHLY_PATYMENT}') //but this is string

您可以将实际值读取为：

def actualPayment = json.CustomerQuoteFinanceResponse.StandardFinanceResponse.Responses[0].StandardPaymentEngineFinanceResponse.paymentWithTaxes.monthlyPaymentWithoutDealerAddOns
log.info actualPayment.class.name //this shows the data type

现在需要将expectedPayment转换为actualPayment的类型

给定此JSON（与提供的完整JSON类似，但具有结束语法）：

考虑以下代码：

def jsonSlurper = new groovy.json.JsonSlurper()
def json = jsonSlurper.parseText(s)
def response = json.CustomerQuoteFinanceResponse
                   .StandardFinanceResponse
                   .Responses[0]

assert 6.75 == response.StandardPaymentEngineFinanceResponse
                       .paymentWithTaxes
                       .financeItemizedTaxes
                       .salesTax
                       .taxParameters
                       .rate as Float

或者，
actualPayment
也可以转换为字符串并进行比较。Srinivasan，您有机会尝试解决方案吗？嗨，Rao，很抱歉，我忙于手动项目，无法按时尝试您的解决方案。在我的代码逻辑中有一个错误，我试图将空字符串转换为十进制，这导致了数字格式异常。非常感谢你的帮助。
