Bogus NuGet package is fake data generator which can be helpful for populating tables in a database and testing purposes. If a database is not used and Bogus populates list of data each time an application runs, the data is random, never the same. Also, the random data generated by Bogus may not meet a developer’s requirements.

AutoFixture

AutoFixture is an open source library for .NET designed to minimize the 'Arrange' phase of your unit tests in order to maximize maintainability. Its primary goal is to allow developers to focus on what is being tested rather than how to setup the test scenario, by making it easier to create object graphs containing test data.

Project mention: API: Go, .NET, Rust | /r/dotnet | 2023-12-09

Yes, it does feel like some of the "standard stuff" in other more nuanced languages are missing (especially miss AutoFixture ngl). Some of those are a conscious decison by the golang team for example.

(My only access to XCode is the copy bundled on the OSX Tiger DVD that I eBayed for the Power Mac G4 I got back in January so I can install StuffIt 2009 when I have time and generate more test files. Aside from that, I keep the machine firmly on MacOS 9.2.2, with a Christmas wishlist entry to buy it a friend that's capable of running System 7.)
