Release Date: Sept 11, 2025
Hey Sparrow Explorers,
We're back with an update designed to supercharge your testing and development workflows! 🚀 Sparrow 2.31 introduces a powerful no-code assertion engine to validate your APIs visually, and a one-click AI tool to generate all the mock data you need. Plus, new guided tours make mastering our best features easier than ever. Let's dive in!
🚀 What’s New?
✅ Introducing No-Code Assertions: Test APIs Without Code!
Ensure your APIs are behaving exactly as you expect—without writing a single line of script. Our new interface for building assertions makes API testing accessible to everyone.
  • Build with Dropdowns: From the "Test" tab, create powerful assertions by selecting a Test Target (like Response JSON, Header, or Time) and a Condition (like Equals, Contains, or Is Empty). The form updates dynamically to guide you!
  • Instant Test Results: After sending a request, a new "Test Results" panel appears at the bottom.
  • Instantly see a breakdown of your assertions, with filterable tabs for All, Passed, and Failed tests.
  • Save Your Assertions: Once you've perfected your test suite, save it directly with your API request for easy regression testing.
  • Guided Tour Included: First time on the Test tab? A "Show Me How" button will launch a step-by-step tour to get you started in seconds.
🤖 Generate Mock Data with a Click!
Tired of manually typing placeholder data? Let Sparrow's AI do the heavy lifting. Instantly Populate Your Requests with Relevant Mock Data
  • One-Click Population: A new "Generate Mock Data" button on the REST API page uses AI to instantly fill your Params, Body, and Headers with relevant data.
  • Smart Highlighting: Data generated by the AI is marked with a special icon and tooltip, so you can easily distinguish it from your manually entered values.
  • Regenerate Anytime: Need a different data set? Just click the button again to replace the old mock data with a fresh set.
  • Save & Go: Happy with the data? Simply save the API changes to keep it for your next session.
✨ Onboarding & Enhancements
We’re making it even easier to unlock Sparrow’s full potential.
🎓 Guided Tour for Smart Variables!
  • For anyone who hasn't yet tried our AI-powered variable generation, we've added a brand-new onboarding experience!
  • Learn the Ropes: A "Show Me How" button will now appear on the Collection Overview for new users.
  • Step-by-Step Walkthrough: Take a 5-step interactive tour to understand how to discover, manage, and use global variables.
  • Focus on Learning: The rest of the UI is disabled during the tour, letting you concentrate on mastering the feature.
⚠️ Known Glitches
Here’s what we’re still refining because perfection takes time:
  • Query Explorer and Editor sync issues might play a bit of hide-and-seek in GraphQL.
  • Dynamic variable creation might lead to partial data capture.
  • Swagger YAML link is not supported while adding a Collection for Active Sync.
  • Sometimes, switching models does not retain the previous logic or context.
  • File upload for LLMs is currently in beta. You may experience occasional issues with uploading, file preview visibility, or model compatibility.
