This is a linkpost for WoofWare.Expect, which implements expect testing in an F# computation expression. Go and read the README on GitHub if you’re interested.

As of this writing, the following are implemented:

• Comparison with existing inline snapshot
• Custom formatting of the snapshot (fully general 'T -> string to override the default .ToString())
• Specific support for JSON snapshotting using FSharp.SystemTextJson, including overriding the default ser/de settings
• “Bulk update” mode for mass regenerating snapshots in a test fixture (which is only slightly unwieldy).
