Module: RSpec::Wait::Handler

Included in:
NegativeHandler, PositiveHandler
Defined in:
lib/rspec/wait/handler.rb

Overview

The RSpec::Wait::Handler module is common functionality shared between the RSpec::Wait::PositiveHandler and RSpec::Wait::NegativeHandler classes defined below. The module overrides RSpec’s handle_matcher method, allowing a block target to be repeatedly evaluated until the underlying matcher passes or the configured timeout elapses.
