Save test case properties if any of the assertions fail - groovy

Question

How to save the test case properties if any of the assertions fail within this groovy script step?
Below is example code:
// define properties required for the script to run.
def groovyUtils = new com.eviware.soapui.support.GroovyUtils(context)
def dataFolder = groovyUtils.projectPath
def vTIDAPI = testRunner.testCase.getPropertyValue("vTIDAPI")
def vTIDDB = testRunner.testCase.getPropertyValue("vTIDDB")
def RefAPI = testRunner.testCase.getPropertyValue("RefAPI")
def RefDB = testRunner.testCase.getPropertyValue("RefDB")
def AmountAPI = testRunner.testCase.getPropertyValue("AmountAPI")
def AmountDB = testRunner.testCase.getPropertyValue("AmountDB")
def CurrencyAPI = testRunner.testCase.getPropertyValue("CurrencyAPI")
def CurrencyDB = testRunner.testCase.getPropertyValue("CurrencyDB")
assert vTIDAPI == vTIDDB
assert RefAPI == RefDB
assert AmountAPI == AmountDB
assert CurrencyAPI == CurrencyDB

Here is the Groovy Script which does compare the given set of properties and on any of the assertion failure, writes the properties to a given file.
You need to change the value of property file name to be stored for variable propFileName variable.
Add more properties to be asserted in the form of key:value pairs format if needed
//Provide / edit the file name to store properties
def propFileName = '/tmp/testCase.properties'
//Define the properties to be matched or asserted ; add more properties if needed
def props = [ 'vTIDAPI':'vTIDDB', 'RefAPI':'RefDB', 'AmountAPI': 'AmountDB', 'CurrencyAPI': 'CurrencyDB']
/**
* Do not edit beyond this point
*/
def writeTestCasePropertiesToFile = {
//Get the test case properties as Properties object
def properties = context.testCase.properties.keySet().inject([:]){map, key -> map[key] = context.testCase.getPropertyValue(key); map as Properties}
log.info properties
assert properties instanceof Properties
properties?.store(new File(propFileName).newWriter(), null)
}
def myAssert = { arg1, arg2 ->
context.testCase.getPropertyValue(arg1) == context.testCase.getPropertyValue(arg2) ? null : "${arg1} value does not match with ${arg2}"
}
def failureMessage = new StringBuffer()
props.collect{ null == myAssert(it.key, it.value) ?: failureMessage.append(myAssert(it.key, it.value)).append('\n')}
if(failureMessage.toString()) {
log.error "Assertion failures:\n ${failureMessage.toString()}"
writeTestCasePropertiesToFile()
throw new Error(failureMessage.toString())
} else {
log.info 'Assertions passed'
}
EDIT: Based on the OP comments
Replace def myAssert = ... with below code fragment.
def myAssert = { arg1, arg2 ->
def actual = context.testCase.getPropertyValue(arg1)
def expected = context.testCase.getPropertyValue(arg2)
actual == expected ? null : "${arg1} value does not match with ${arg2} - api ${actual} vs db ${expected}"
}
