Postman - Collection Runner

Postman Collection Runner is used to execute a Collection having multiple requests together. All the requests within a Collection will be executed simultaneously. The Collection Runner does not produce any Response Body.

The Collection Runner console displays the test results for individual requests. It is mandatory to have more than one request within the Collection to work with Collection Runner.

The details on how to create a Collection is discussed in detail in the Chapter on Create Collections.
