Simulation Tests

This directory contains the simulation tests for the simapp module

Test Cases

Non-Determinism

make test-sim-nondeterminism

This test case checks that the simulation is deterministic. It does so by running the simulation twice with the same seed and comparing the resulting state. If the simulation is deterministic, the resulting state should be the same.

Full App

make test-sim-default-genesis-fast

This test case runs the simulation with the default genesis file. It checks that the simulation does not panic and that the resulting state is valid.

Import/Export

make test-sim-import-export

This test case runs the simulation with the default genesis file. It checks that the simulation does not panic and that the resulting state is valid. It then exports the state to a file and imports it back. It checks that the imported state is the same as the exported state.

Simulation After Import

make test-sim-after-import

This test case runs the simulation with the default genesis file. It checks that the simulation does not panic and that the resulting state is valid. It then exports the state to a file and imports it back. It checks that the imported state is the same as the exported state. It then runs the simulation again with the imported state. It checks that the simulation does not panic and that the resulting state is valid.

Params

A params.json file is included that sets the operation weights for CreateValidator and EditValidator to zero. It's a hack to make the simulation tests pass. The random commission rates sometimes halt the simulation because the max commission rate is set to 0.25 in the AnteHandler, but sometimes the random commission rate is higher than that. The random commission is set by the cosmos-sdk x/staking module simulation operations, so we have no control over injecting a manual value.
