exception sismic.exceptions.ContractError(configuration=None, step=None, obj=None, assertion=None, context=None)

Bases: sismic.exceptions.SismicError

Base exception for situations in which a contract is not satisfied. All the parameters are optional, and are exposed to ease debug.

Parameters

• step – a MicroStep or MacroStep instance.

• obj – the object that is concerned by the assertion

• assertion – the assertion that failed

• context – the context in which the condition failed
