Duplicate Handler

duplicate-handler

Different effective matchers use the same non-trivial handler after parameter and local-variable normalization. Empty, pending, unresolved, and otherwise non-comparable handlers are excluded. Exact handler matches also require equal behavior signatures. Handlers whose assertion arguments reference unresolved external values are excluded from handler comparisons; matcher checks still run. Consider one parameterized definition, but retain separate definitions when shared implementation is intentional domain vocabulary.

Language support

JavaScript/TypeScript	Cucumber-Ruby
Supported, with assertion evidence from recognized assertion packages.	Exact supported handler structure. Assertion evidence comes only from an explicitly configured provider; RSpec, Minitest and Capybara assertions are compared as ordinary calls. Unresolved captures, constants or receiver identity make the handler non-comparable and the run incomplete.

Cucumber-Ruby support is experimental; see Cucumber-Ruby.
