Top 4 C# test-data Projects
-
Bogus
:card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js.
Project mention: Why I moved from AutoFixture to Bogus for test data generation for C#/xUnit tests | dev.to | 2025-07-05AutoFixture and Bogus are both well-known libraries for generating test data in C# tests. AutoFixture is, well, dated whereas Bogus is state of the art.
-
InfluxDB
InfluxDB – Built for High-Performance Time Series Workloads. InfluxDB 3 OSS is now GA. Transform, enrich, and act on time series data directly in the database. Automate critical tasks and eliminate the need to move data externally. Download now.

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.
