octez-protocol-alpha-libs 20.1 (latest)

This module centralises all modules related to Scenario writing and execution. Most scenario tests would use most if not all of them, so they only need to open Scenario.

type Tezos_base.TzPervasives.error +=

| Unexpected_error

For assert_failure, when expected error does not match the actual error.

type Tezos_base.TzPervasives.error +=

| Slow : ('t, 't) scenarios

A scenario is a succession of actions. We define a branching path as a way to create multiple tests from the same point. This allows easy compositionality of behaviors with minimal code sharing. The Tag allows to give meaningful identifiers to the branches. It is good practice to tag each case in a branch (it's not necessary, but since test names must be unique, at most one branch can remain unnamed, and even then it can create conflicting names.)
