# Stratis.SmartContracts.TestChain

A C# library to help with local testing of smart contracts.

See below for an example of how to use this tool in code.

```cs

using Stratis.Bitcoin.Features.SmartContracts.Models;

using Stratis.SmartContracts.CLR.Compilation;

using Stratis.SmartContracts.CLR.Local;

using Xunit;

namespace Stratis.SmartContracts.TestChain.Tests

{

    public class TestChainExample

    {

        [Fact]

        public void TestChain_Auction()

        {

            // Compile the contract we want to deploy

            ContractCompilationResult compilationResult = ContractCompiler.CompileFile("SmartContracts/Auction.cs");

            Assert.True(compilationResult.Success);

            using (TestChain chain = new TestChain().Initialize())

            {

                // Get an address we can use for deploying

                Base58Address deployerAddress = chain.PreloadedAddresses[0];

                // Create and send transaction to mempool with parameters

                SendCreateContractResult createResult = chain.SendCreateContractTransaction(deployerAddress, compilationResult.Compilation, 0, new object[] { 20uL });

                // Mine a block which will contain our sent transaction

                chain.MineBlocks(1);

                // Check the receipt to see that contract deployment was successful

                ReceiptResponse receipt = chain.GetReceipt(createResult.TransactionId);

                Assert.Equal(deployerAddress, receipt.From);

                // Check that the code is indeed saved on-chain

                byte[] savedCode = chain.GetCode(createResult.NewContractAddress);

                Assert.NotNull(savedCode);

                // Use another identity to bid

                Base58Address bidderAddress = chain.PreloadedAddresses[1];

                // Send a call to the bid method

                SendCallContractResult callResult = chain.SendCallContractTransaction(bidderAddress, "Bid", createResult.NewContractAddress, 1);

                chain.MineBlocks(1);

                // Call a method locally to check the state is as expected

                ILocalExecutionResult localCallResult = chain.CallContractMethodLocally(bidderAddress, "HighestBidder", createResult.NewContractAddress, 0);

                Address storedHighestBidder = (Address)localCallResult.Return;

                Assert.NotEqual(default(Address), storedHighestBidder); // TODO: A nice way of comparing hex and base58 representations

            }

        }

    }

}
