Running a Bruno collection lets you exercise and test an API. You can run collections from the app (Collection Runner) or from the command line (Bruno CLI).

Collection Runner

The built-in Collection Runner supports unlimited runs.
  1. Open the Collection Runner using either method:
    • In the sidebar, click ··· next to your collection, then select Run. Click Run from collection menu
    • Or click the Collection Runner icon in the top bar. Collection Runner icon in the top bar
  2. Configure the run (optional): In the runner, set parameters, choose a delay between requests, and adjust any other options you need.
  3. Start the run to execute the collection from the runner.
The Collection Runner does not include gRPC and WebSocket requests. Only HTTP requests will be executed when running a collection.
Data-driven testing (running a collection with a CSV data file) is available in Bruno Pro and Bruno Ultimate.
