[SoapUI] 重载JSONComparator比对JSON Response，忽略小数点后几位，将科学计数法转换为普通数字进行比对

重载JSONComparator比对JSON Response，忽略小数点后几位，将科学计数法转换为普通数字进行比对

封装的脚本：

package direct

import org.skyscreamer.jsonassert.*
import org.skyscreamer.jsonassert.comparator.*
import org.json.*
import net.sf.json.JSONException
import java.text.NumberFormat

public class LooseyJSONComparator extends DefaultComparator {
	def log
	
	def regEx_Numeric = '-?[1-9]\d*$|-?([1-9]\d*\.\d*|0\.\d*|0?\.0+|0)$'
    def regEx_ScientificNotation = '^((-?\d+.?\d*)[Ee]{1}(-?\d+))$'   //科学计数法正则表达式
 
    int decimalPrecision = 5 //Defaultly compare 5 decimal places

    public LooseyJSONComparator(JSONCompareMode mode) {
        super(mode)
    }

    public static void assertEquals( Object expected, Object actual) throws JSONException {
        JSONCompareResult result = JSONCompare.compareJSON(expected, actual, new LooseyJSONComparator(JSONCompareMode.LENIENT))
        if (result.failed()) {
            throw new AssertionError(result.getMessage())
        }
    }

    @Override
    public void compareValues(String prefix, Object expectedValue, Object actualValue, JSONCompareResult result)
            throws JSONException {
        if (expectedValue instanceof String && actualValue instanceof String) {
			def expectedValueTemp=formatDecimalPrecision(expectedValue)
        	def  actualValueTemp=formatDecimalPrecision(actualValue)
            if (expectedValueTemp!=actualValueTemp){
                result.fail(prefix, expectedValue, actualValue)
            }
         } else if (expectedValue.getClass().isAssignableFrom(actualValue.getClass())) {
				if (expectedValue instanceof JSONArray) {
	                compareJSONArray(prefix, (JSONArray) expectedValue, (JSONArray) actualValue, result)
	            } else if (expectedValue instanceof JSONObject) {
	                compareJSON(prefix, (JSONObject) expectedValue, (JSONObject) actualValue, result)
	            } else if (!expectedValue.equals(actualValue)) {
	                result.fail(prefix, expectedValue, actualValue)
	            }
        } else {
            result.fail(prefix, expectedValue, actualValue)
        }
    }

    def formatDecimalPrecision(def dataValue){
	    NumberFormat format = NumberFormat.getNumberInstance()
	    format.setMaximumFractionDigits(decimalPrecision)
	         
	    dataValue = dataValue.toString()
	         
	    if(dataValue.matches(regEx_ScientificNotation)){
			BigDecimal db = new BigDecimal(dataValue)
			dataValue = db.toPlainString()
	    }
	         
	    if(dataValue.matches(regEx_Numeric)){
			dataValue = Double.parseDouble(dataValue) 
			dataValue = format.format(dataValue)
	    }
	    return dataValue
	}
}

SoapUI里面如此调用

package direct
import org.json.*

def currentStepIndex = context.currentStepIndex
def previousStepName = testRunner.testCase.getTestStepAt(currentStepIndex-1).name
def prePreStepName = testRunner.testCase.getTestStepAt(currentStepIndex-2).name

def expectedJsonResponse =new JSONObject("{"long-rescale":"1.519719","short":"0.105816","net":"1.477390","long":"1.583196"}")
def actualJsonResponse = new JSONObject("{"long-rescale":"1.519715","short":"0.105806","net":"1.477390","long":"1.583196"}")

LooseyJSONComparator.assertEquals( expectedJsonResponse, actualJsonResponse)

　　

输出结果：

 如果是通过获取test step的response来比对，脚本如下：

package direct
import org.json.*

def currentStepIndex = context.currentStepIndex
def previousStepName = testRunner.testCase.getTestStepAt(currentStepIndex-1).name
def prePreStepName = testRunner.testCase.getTestStepAt(currentStepIndex-2).name

try{
	def expectedJsonResponse = new JSONObject(context.expand( '${'+prePreStepName+'#Response}' ))
	def actualJsonResponse = new JSONObject(context.expand( '${'+previousStepName+'#Response}' ))
	LooseyJSONComparator.assertEquals( expectedJsonResponse, actualJsonResponse)
}catch(JSONException e){
	assert false,"HTTP Response returns wrong, please have a check"
}
