-- [`AssertionContexts`](../../Sources/CollectionsTestSupport/AssertionContexts): Custom test assertions with support for keeping track of nested context information, including stopping execution when the current context matches a particular value. (Useful for debugging combinatorial tests.)

-- [`Combinatorics`](../../Sources/CollectionsTestSupport/AssertionContexts/Combinatorics.swift): Basic support for exhaustive combinatorial testing. This allows us to easily verify that a collection operation works correctly on all possible instances up to a certain size, including behavioral variations such as unique/shared storage. This file also contains a basic set of functions for executing the same test code for all subsets or all permutations of a given collection, with each iteration registered in the current test context, for easy reproduction of failed cases.

-- [`ConformanceCheckers`](../../Sources/CollectionsTestSupport/ConformanceCheckers): A set of generic, semi-automated protocol conformance tests for some Standard Library protocols. These can be used to easily validate the custom protocol conformances provided by this package. These checks aren't (can't be) complete -- but when used correctly, they are able to detect most accidental mistakes.

     We currently have conformance checkers for the following protocols:
 
-    - [`Sequence`](../../Sources/CollectionsTestSupport/ConformanceCheckers/CheckSequence.swift)
-    - [`Collection`](../../Sources/CollectionsTestSupport/ConformanceCheckers/CheckCollection.swift)
-    - [`BidirectionalCollection`](../../Sources/CollectionsTestSupport/ConformanceCheckers/CheckBidirectionalCollection.swift)
-    - [`Equatable`](../../Sources/CollectionsTestSupport/ConformanceCheckers/CheckEquatable.swift)
-    - [`Hashable`](../../Sources/CollectionsTestSupport/ConformanceCheckers/CheckHashable.swift)
-    - [`Comparable`](../../Sources/CollectionsTestSupport/ConformanceCheckers/CheckComparable.swift)
-
-- [`MinimalTypes`](../../Sources/CollectionsTestSupport/MinimalTypes): Minimally conforming implementations for standard protocols. These types conform to various standard protocols by implementing the requirements in as narrow-minded way as possible -- sometimes going to extreme lengths to, say, implement collection index invalidation logic in the most unhelpful way possible.
