Collection Runner

The Collection Runner executes all requests in a collection and displays results with pass/fail status, response times, and test assertions.

Video Walkthrough

How to Open

• Right-click on any collection and select Run All.
• The Run Collection view opens where you can configure and start the run.

Run Types

• Sequential — Runs requests one after another. Use this when requests depend on each other, such as logging in before creating a product or placing an order.
• Parallel — Runs all requests simultaneously. Use this for independent requests when speed matters.

Skip

• Click the Skip button on a request or folder to exclude it from the run.
• Skipped items remain in the collection and can be re-enabled at any time.

Data File

Use a data file when you want to test the same flow with different inputs — for example, registering multiple users in one run.

• Attach a CSV or JSON file to run the same request with multiple datasets.
• Column headers (CSV) or keys (JSON) become the variable names in your request body.
• {{username}}, {{email}}, and {{password}} are replaced with values from each row.

Example CSV

username,email,password
alice,alice@example.com,Pass@123
bob,bob@example.com,Pass@456
carol,carol@example.com,Pass@789

Example JSON

[
  { "username": "alice", "email": "alice@example.com", "password": "Pass@123" },
  { "username": "bob", "email": "bob@example.com", "password": "Pass@456" },
  { "username": "carol", "email": "carol@example.com", "password": "Pass@789" }
]

Iterations

• Set the number of times the collection should run.
• Default is 1.
• When using a data file, set iterations to match the number of rows — each row represents one iteration.

Delay

• Set a delay between requests in milliseconds.
• Default is 0 (no delay).

Results

After the run, each request displays:

• Pass / Fail status
• Response time
• Test assertion results

Click any request in any iteration to view the full response body, headers, and individual assertion details.

Export Reports

• Click Export after the run to save results.
• Supported formats: JSON, HTML, XML.

Run from CLI

Collections can also be run from the terminal without opening the extension. See the CLI documentation for details.
