Overview ¶
Package 'solo' is a development tool to write unit tests for IOTA Smart Contracts (ISC).
A development tool ¶
The package is intended for developers of smart contracts as well as contributors to the development of the ISC and the Wasp node itself.
Normally, the smart contract is developed and tested in the 'solo' environment before trying it out on the network of Wasp nodes. Running and testing the smart contract on 'solo' does not require to run the Wasp nodes nor committee of nodes: just ordinary 'go test' environment.
Native environment ¶
'solo' shares the same code of Virtual Machine with the Wasp node. This guarantees that smart contract programs can later be deployed on chains which are run by the network of Wasp nodes without any modifications.
The 'solo' environment uses in-memory UTXO ledger to validate and store transactions. The UTXODB mocks the Shimmer UTXO ledger, it uses same value transaction structure, colored tokens, signature schemes as well as transaction and signature validation as in the Value Tangle of Shimmer. The only difference with the Value Tangle is that UTXODB provides full synchronicity of ledger updates.
The virtual state (key/value database) in 'solo' is an in-memory database. It provides exactly the same interface of access to it as the database of the Wasp node.
Writing smart contracts ¶
The smart contracts are usually written in Rust using Rust libraries provided in the 'wasplib' repository at https://github.com/iotaledger/wasplib. Rust code is compiled into the WebAssembly (Wasm) binary. The Wasm binary is uploaded by 'solo' onto the chain and then loaded into the VM and executed.
Another option to write and run ISC smart contracts is to use the native Go environment of the Wasp node and 'Sandbox' interface, provided by the Wasp for the VM: the "hardcoded" mode. The latter approach is not normally used to develop apps, however is used for the 4 builtin contracts which constitutes the core of the ISC chains. The approach to write "hardcoded" smart contracts may also be very useful for the development and debugging of the smart contract logic in IDE such as GoLand, before writing it as a Rust/Wasm smart contract.
Example test ¶
The following example deploys chain and retrieves basic info from the deployed chain. It is expected 4 core contracts deployed on it by default and the test prints them.
func TestSolo1(t *testing.T) { env := solo.New(t, false, false) chain := env.NewChain(nil, "ex1") chainInfo, coreContracts := chain.GetInfo() // calls view root::GetInfo require.EqualValues(t, 4, len(coreContracts)) // 4 core contracts deployed by default t.Logf("chainID: %s", chainInfo.ChainID) t.Logf("chain owner ID: %s", chainInfo.ChainOwnerID) for hname, rec := range coreContracts { t.Logf(" Core contract '%s': %s", rec.Name, isc.NewContractID(chain.ChainID, hname)) } }
will produce the following output:
