Getting Started

Truffle Testing

Documentation is here, video instructions is here (starts at 1:34). The following installations are written for a Linux system:

1. install npm on device

   sudo apt install npm
   

2. Install truffle

   sudo npm install -g truffle
   

3. Run truffle test to verify if your bounty contract works.

   truffle test
   

Manual Testing

Besides the automated testing using Truffle, you can also manually test your smart contracts. To do so you can look at AskContract which consists of a square root problem and the SolveContract which is able to solve the problem.

Test:

• Open both contracts in https://remix.ethereum.org
• Compile (ctrl+s) and select the AskContract (Not the template!), deploy it (optionally add a value to it)
• Copy the contract address of the AskContract
• Compile and select the SolveContract (Not the template!), paste the copied address in the deploy field and deploy it
• Finally, click on the SolveContract and click on the ‘solve’ function
• Now the funds should be transferred to the owner of the SolveContract

TestRefund:

• Change the expiry value in the contract to a future experidate (unix timestamp)
• Compile and select the AskContract, deploy it with a value
• Click on the AskContract and try to get the refund, when it is past your timestamp it should self-destruct otherwise it should not work

Note that only the owner of the contract (which is the person who either created or solved the contract) can activate the refund function.
