Testing Playground
Testing Playground – GearUp Studio
Simulate, test, and debug your contract logic before deploying — all visually, no code required.
The Testing Playground in GearUp Studio allows individuals to simulate their contracts in a safe, real-time environment before deploying them to the blockchain. With just a few clicks, you can test your full contract logic using sample wallets, tokens, and time-triggers — without writing a single line of code.
🎯 Why Testing Matters
Smart contracts are immutable once deployed. The Testing Playground allows you to:
- Catch logic errors before they go live 
- Simulate user interactions (wallets, transfers, time triggers) 
- Preview gas usage, execution order, and flow behavior 
- Validate blocks working together (e.g. triggers, actions, restrictions) 
- Ensure security and flow safety using test scenarios 
🧪 What You Can Simulate
- ✅ Transfers, swaps, tax collections 
- ✅ Wallet role logic (e.g. - onlyOwner, whitelisting)
- ✅ Timed triggers (e.g. “every 24h” or “after 7 days”) 
- ✅ Event conditions (e.g. “if market cap hits X”) 
- ✅ Multistep flows (e.g. “collect + swap + distribute”) 
You can also simulate errors like insufficient balances, missing inputs, or blocked access.
🧱 How to Use the Playground
- Open your contract in the Studio Canvas 
- Click “Test Mode” 
- Choose a simulated chain (e.g. Linea Sepolia, Local VM) 
- Select test wallets, balances, and token conditions 
- Execute specific functions or full contract flows 
- Review logs, return values, and warnings 
You can run as many tests as you want — no gas fees, no risks.
🔍 Visual Execution Flow
During simulation, you’ll see:
- Active block execution path (highlighted) 
- Gas estimation per block 
- Return values per action 
- Warnings for untriggered logic or failed conditions 
All logs are shown in a readable format (e.g. “User X sent 1 ETH → Swap → Treasury received 990 USDC”).
🧠 Scrappy AI Support
While testing, you can:
- Ask Scrappy AI to explain what went wrong 
- Get help modifying your logic on the spot 
- Ask for optimization advice (e.g. “Can I reduce gas here?”) 
- Debug a function using error analysis tools 
Example:
Q: Why didn’t this LP add function trigger?
Scrappy: “The LP Add block requires ETH balance ≥ 0.5. Try increasing test wallet funding.”🔁 Testnet Deployment (Advanced)
Once you're confident, click “Deploy to Testnet”:
- Deploys your contract to Linea Sepolia or other supported testnets 
- Real interaction with test wallets and tokens 
- Simulate user usage in a live but risk-free environment 
Use this to prepare for real-world deployment and confirm logic integrity on-chain.
🛠️ What’s Coming Next
- Collaborative testing (team test flows) 
- Live transaction simulation against public contracts 
- Fork testing (simulate state from real block height) 
- AI-powered test cases generator 
The Testing Playground gives you complete confidence in your contracts — no guesswork, no risks, just clear results.
