massa-sc-tester is a minimal testing environment made to run massa smart contracts. This program provides a human-readable execution trace and ledger.
massa-sc-tester currently mimics the behaviour of the TEST.21.0 node.
The default configuration located at config/execution_config.yaml contains a detailed example of what you can do with massa-sc-tester. The json format is also supported if you wish to integrate massa-sc-tester in another application but for human interaction yaml is recommended.
cargo run config/execution_config.yaml
After running a massa-sc-tester instance, you can read the execution trace in trace.json and the resulting ledger in ledger.json. The ledger is persistent, it will be loaded in the next execution if present. The trace will be overridden.
