Class Attribute Details

.failure_context ⇒ Object

A ->(subject) { String | nil } consulted when a matcher fails: its return value is appended to the failure message. Hosts set this to add context (dommy-rails registers a recent-trace summary for trace-enabled sessions). nil (the default) leaves every message untouched.

Class Method Details

.__decorate_failure(message, subject) ⇒ Object

Append the host's failure context to message for subject, or return message unchanged. Never raises out of a failure path: a misbehaving context proc must not mask the real assertion failure.
