WGGraph

class WGGraph[S] extends GenericSolver[S, Event]

A tester for linearizabilty.

This is the tester referred to as the Wing & Gong Graph-Search in the paper Testing for Linearizability, Gavin Lowe. See that paper for more explanation of the technique.

The algorithm is based on the algorithm in Testing and Verifying Concurrent Objects, by Jeannette Wing and Chun Gong, extended to recognise revisited configurations.

S

the type of states of the corresponding sequential datatype
