FsCheck

FsCheck is a tool for testing .NET programs automatically. You provide a specification of the program, in the form of properties which functions, methods or objects should satisfy, and FsCheck then tests that the properties hold in a large number of randomly generated cases. Such properties are actually a testable specification of your program. Properties are written in F#, C# or VB. FsCheck helps you to define properties, observe the distribution of test data, and define test data generators. Crucially, when a property fails, FsCheck automatically displays a minimal counter example.

FSharp.Data

The FSharp.Data packages contain type providers and utilities to access common data formats (CSV, HTML, JSON and XML in your F# applications and scripts. * FSharp.Data -- includes everything * FSharp.Data.Http -- http types/helpers * FSharp.Data.Csv.Core -- csv types/helpers * FSharp.Data.Json.Core -- json types/helpers * FSharp.Data.Html.Core -- html types/helpers * FSharp.Data.Xml.Core -- xml types/helpers

FParsec

FParsec is a parser combinator library for F#. You can find comprehensive documentation for FParsec at http://www.quanttec.com/fparsec. The documentation includes a feature list, a tutorial, a user’s guide and an API reference. This package uses the basic “low-trust” configuration of FParsec, which does not use any unverifiable code and is optimized for maximum portability. If you need to parse very large files or if you employ FParsec for performance-critical jobs, consider using the alternate “Big Data Edition” NuGet package (see https://nuget.org/packages/fparsec-big-data-edition).

FsToolkit.ErrorHandling

FsToolkit.ErrorHandling is an extensive utility library based around the F# Result type, enabling consistent and powerful error handling.
