Overview

Package teststore provides a common.Storage implementation for testing/mocking purposes.

A new teststore.TestStore can be obtained with teststore.New. Whenever one of the common.Storage methods is called, the implementation selects what function to call in the following order:

  1. If an override for that method was provided at construction time (via teststore.WithXXX()) or afterwards via SetOption, that override is used.
  2. If a substorage was provided at construction time (via teststore.WithSubstorage()) or afterwars via SetOption, the corresponding method in the substorage is used.
  3. If none of the above apply, the call panics with an error describing the unexpected call.

It's safe to call SetOption and the overrides from multiple goroutines, but it's the override's responsibility to ensure safety of whatever operation it executes.
