can you explain how to send the post request with multiple customer details including file via form-data from the postman?

Hey man, thanks for the video. How would turn the columns of a csv containing thousands of rows into the key value pairs of each object or iteration? Hope that makes sense.

[hamedkhatami]

very informative video, thank you, how can I export the Req. and Res. body of all iterations?

[paulofreitasview]

Its possible to do this but without the runner?? like calling the external data by code or by javascript inside of pre-request script??

Hi Valentin,


This is a nice tutorial and thank you very much for that. But I have a question here if I want to run the Postman scripts in CICD pipeline then is there any way to use the external .json data file in scripts as in batch mode we are not able to select file from Postman collection. Any command is available to add that .json file with collection file so that every thing works fine in pipe line ?


Appreciate your response on this.


Thanks,
Abhishek

@Valentin: thank you - these tutorials are great. Could you please explain how you handle your assertions in tests when using a data driven case like this? Your tests were failing due to the dynamic data you passed in - how do you similarly make your tests dynamic?
Could you include the expected result in each array and then parameterise your tests too? In that way you are passing in not only the dynamic data for the request, but dynamic data for the test, too?

[cristhianlopez]

@valentin Despa is possivel to run a collecion setting an env variable with any code(pm.set.enviorenment etc etc) and at the same time send values for others end points in the CSV? The end point that use the CSV file need the Env variables... Is that possivel?

[harishshet]

Hi, Thanks for the video, I have one doubt, assume I have 2 files inside the folder, and I wrote some test cases in .json file, both the files contains a post request and both are hitting to different end points, I want few test cases to get tested in first request, and other cases in second req file, how to distinguish between them, or we have only one request file in a directory? Thanks
