Any suite that embeds `SimulatedBackendsTestSuite` will have simulated backend and messaging contract scaffolding for Summit, Origin, and Desination chains. This includes `TestExecutorSuite`, `TestGuardSuite`, `TestNotarySuite`, `ExampleAgentSuite`, and `AgentsIntegrationSuite`. To run all agent tests: ```bash cd agents go test -v ./... ``` To run an individual suite (for example, `TestExecutorSuite`): ```bash cd agents/executor go test -v ``` To run an individual test (for example, `TestVerifyState`): ```bash cd agents/executor go test -v -run TestExecutorSuite/TestVerifyState ```
