Re: 3.8.1 Unable to generate data in data source

@nemowbray 

You may report the issue with Smartbear customer support.

 

Mean while you can try below if you want UUID.

In the Data Source drop down box, select Groovy

And add below line.

 

# assuming that test_id is property you have added on left side
result['test_id'] = UUID.randomUUID().toString()	

 Please if this resolves the issue for now and let you proceed.

Rao.

Re: 3.8.1 Unable to generate data in data source

Hey @nemowbray,

If you just need unique GUIDs/UUIDs in certain fields in your payloads you can try the dynamic scripting option as follows:

"jsonAttribute": "${=java.util.uuid.randomuuid()}"

Using the above you wont need to use the datagenerator.

Cant actually take credit for this as it was @nmrao that showed me!😉

Nice one
