You can test multiple requests using Collection, select Run All option from the collection menu.
The collection runner will execute all requests and test cases and display the result.

Proxy is supported using vscode proxy setting. format http://username:password@host:port

I noticed we need to write lot of boilerplate code in Postman and other clients to do basic testing using scripting like status code equal 200. So I implemented GUI based tests, where you select couple of dropdowns to do most standard tests very easily without any scripting knowledge.
Set Environment Variable from response, Headers, Cookie in Tests tab is now supported, see our github page for details.

Basic anonymised telemetry data of extension usage is collected using vscode-extension-telemetry, No Personal or request data is collected. You can opt out using VS Code Settings details here
