evolve-testing

Unit testing in the Evolve SDK uses TestApp to set up a test harness for your Rust module, providing an isolated environment to verify transaction execution and module logic. TestApp is designed for fast, targeted validation of individual components without requiring a full network setup.

For deterministic simulations of blockchain applications, the Evolve SDK provides SimTestApp, which ensures consistent execution outcomes by controlling the testing environment. SimTestApp allows developers to simulate complex transaction sequences and verify state transitions reliably across test runs.

MockEnv works by providing a mocked environment that isolates a specific module from external dependencies during Rust testing. This allows you to test module behavior in a controlled context, ensuring that interactions and state changes are verified independently of the broader blockchain application infrastructure.

Yes, you can benchmark Evolve SDK blockchain modules using Criterion, which is integrated into the testing infrastructure for performance testing. Criterion allows you to measure execution times of transactions and module operations, helping identify performance bottlenecks in deterministic or simulated environments.

Use transaction generators in blockchain integration testing when you need to create complex scenarios involving multiple sequential or interacting transactions. The Evolve SDK provides transaction generators to automate the construction of these testing scenarios, ensuring comprehensive coverage of edge cases and state transitions.

To capture execution traces for debugging blockchain modules, use the trace recording feature built into the Evolve SDK testing infrastructure. Trace recording allows you to log detailed execution steps and state changes during tests run with TestApp or SimTestApp, enabling precise debugging of transaction logic.
