VS Code Extension
Microsoft maintains an excellent VS Code extension based on Copilot that helps you create and run Locust tests.
Among other things, it can:
Create locustfiles from .http files, Postman collections or Insomnia collections
Run tests locally or scale up using Azure Load Testing
Fetch insights and help implement performance suggestions based on test results
