Hiya
files are created by SoapUI only, and not in use by anything else
for ref due to the way the service response is returned to control the flow and ensure that all test data is returned as expected I'm iterating across the datasource using groovy as per below,
the assertion test step ('Verify Data in DS') compares the response from the service request response elements to the content of the datasource
the datasource uses a csv file that is created from a separate test suite that interrogates the back end db
def CurrentRow
def DSRowCount = testRunner.testCase.testSteps['DatasourceToUse'].rowCount
log.info '## DatasourceToUse rowcount = '+ DSRowCount
for (i = 1; i<=DSRowCount; i++)
{
CurrentRow = testRunner.testCase.testSteps['DatasourceToUse'].currentRow
CurrentRow = CurrentRow.toString()
log.info 'DatasourceToUse Row No = ' + CurrentRow
result = testRunner.runTestStepByName("Verify Data in DS");
log.info "@@ Verify Data in DS = "+result.getStatus()
result = testRunner.runTestStepByName("DataSource Loop");
log.info "@@ DataSource Loop = "+result.getStatus()
}
