Hello Valentine, I tried almost the same thing i.e passing an array of values to an api and when i executed the same API i got a message "There are no test for this request". Why am i getting this message?

Thanks for the guide. I followed it from the start to finish, however when I try to run the collection, my request is executed only once and I see the "No tests found" message. Any ideas what is wrong?

[LaTernurin]

Michas gracias, me ayudo mucho con este ejemplo para aplicarlo. Excelente tutorial

[OliverUnderTheMoon]

Thank you for this helpful video. I chose to use:
if (companies instanceof Array && companies.length > 0) {
and:
if (!(companies instanceof Array)) {
instead of truthy evaluation because maybe some non-array value could evaluate to true.

I am using the same code to insert [ "7666", "3333", "6667"] values and running through collection runner but I see only one request being called and the other are not even shown. Please help me

What should i do when i have multiple variables to be changed. Example company name and address

[christopherhoup]

I have followed your example exactly as you've coded, but my post only runs once and stops after Google.

[sibanidevi]

I am unable to pass multiple values using the approach mentioned in the video, its only executing first value provided once only

Your Postman related tutorials are great. Related to this one I do not understand the advantage of the pre-request script instead of using data file when running a collection. Seems easier for me to create a csv/json file and select it in Collection Runer.

HOw can I execute same api with diiferent files in a folder. Each file is selected in the upload field as binary data ?

[VictorDabela]

Great video!

It helped me a lot to solve some massive integration problem with multiple customers.

Thanks!

postman.setNextRequest("xyz") throwing BAD Request 400, please suggest

[meandherforeternity]

Awesome. You saved my day, liked and subscribed your channel :)

[apekshapatel]

Thank you very much!! this is exactly I am looking....getting after a lot of searches.

[AlessiaCaraFans]

is it possible to do the same without collection runnet, just scripts in postman ? to save multiple datasets from csv file?

[narekumar]

More Useful and thanks for covering the scenario which I am looking for, Much Appreciated

[alextreme]

Put the request name inside the setNextRequest surrounded by ' ' not " " ... it won't work otherwise

[dhavaljardosh]

How can I pass a whole object as variable instead of just passing it as a value in Key-Value pair?
What I mean is instead of passing "name": {{companies}} . can I pass only {{company_object}} where company_object = {"name": "Company Name"}..

[ezekieludoh]

Hi Valentin, thanks for the tutorial. It was awesome. I guess what I would need some pointers on is how to write tests for each new NAME you are passing into theAPI requests. Something like: if the name is "Google", assert the response is 200, if the name is "Facebook", assert the response is 409. How can I loop through tests per request value?
