How to Upload a CSV file Via Groovy Script using SOAPUI Open Source ?

where are you wanting to upload a file to? I've used scripts to do similar things but they are specific to where I am loading them to.

Here is some groovy for loading a file to a service that uploads files. It calls the REST API and loads the details to the "Attachment" tab on the service request.

// encode file
ResultsPath = context.testCase.getPropertyValue("resultFilePath")
def inputFile = new File(ResultsPath)
String encoded = inputFile.bytes.encodeBase64().toString()
testRunner.testCase.setPropertyValue("EncodedFileRequest", "$encoded" )

// get request
def request = testRunner.testCase.getTestStepByName( "AttachmentContentRequest" ).testRequest

// clear existing attachments
for( a in request.attachments ) {
request.removeAttachment( a )
}

// get file to attach
ResultsPath = context.testCase.getPropertyValue("resultFilePath")
def file = new File(ResultsPath)
if ( file == null) {
log.info "bad filename"
}
else
{

// attach and set properties
def attachment = request.attachFile( file, true )
attachment.contentType = "base64Binary"
attachment.setPart( "Message" )
}
