ribs_test

Test utilities and matchers for all ribs packages.

Re-exports ribs_core_test, ribs_effect_test, and ribs_rill_test as a single convenience import.

Classes

Class	Description
TestIORuntime	A deterministic IORuntime for testing IO programs.
Ticker<A>	A test harness that pairs an IO program with a TestIORuntime, providing fine-grained control over time advancement and task execution.

Extensions

Extension	on	Description
IOTickedOps<A>	IO<A>	Extension on IO to create a Ticker for deterministic testing.

Functions

Function	Description
errors	A matcher that asserts an IO completes with an error.
expectIO	Lifts a test expectation into IO, allowing assertions to be composed within an IO program.
isInvalid	Returns a Matcher that matches an Invalid value.
isLeft	Returns a Matcher that matches a Left value.
isNone	Returns a Matcher that matches a None value.
isRight	Returns a Matcher that matches a Right value.
isSome	Returns a Matcher that matches a Some value.
isValid	Returns a Matcher that matches a Valid value.
isValidNel	Returns a Matcher that matches a Valid value for a ValidatedNel.
producesError	Matches a Rill that fails with an error satisfying matcher.
producesInOrder	Matches a Rill that emits elements in the exact order given by expected.
producesNothing	Matches a Rill that succeeds without emitting any elements.
producesOnly<A>	Matches a Rill that emits exactly the single element a.
producesSameAs<A>	Matches a Rill that produces the same outcome (success, error, or cancelation) and the same elements as expected.
producesUnordered	Matches a Rill that emits the same elements as expected in any order.
succeeds	A matcher that asserts an IO completes successfully.

Constants

Constant	Description
cancels	A matcher that asserts an IO is canceled before completion.
nonTerminating	A matcher that asserts an IO does not terminate (runs forever) when evaluated with a TestIORuntime.
terminates	A matcher that asserts an IO terminates (completes in finite time) when evaluated with a TestIORuntime.
