C# library to populate object with random data [closed]

Answer 1

Since some libraries are either a bit outdated or no longer under development, I have created my own library Oxygenize, which enables you to populate classes with either random or customized data.

Answer 2

NBuilder is pretty nice.

I believe it uses reflection as well.

Answer 3

NBuilder is a very good fluent-API library for generating data. It uses rules that you define and isn't "random" per se. You may be able to randomize the inputs to the API, though, to suit your needs.

Since this still gets some attention I think it's worth mentioning the project is now available through NuGet (https://www.nuget.org/packages/NBuilder/) as well, though it hasn't been modified since 2011.

Answer 4

I tried AutoFixture (https://github.com/AutoFixture/AutoFixture) and it worked for me very well. It can easilty generate an object with a deep hierarchy of children in one line of code.

Answer 5

I've recently been working on one that is exactly like what you described (maybe it's been done before but this seemed like a fun project to try). It is still a work in progress but I think it captures all the features you mentioned. You can find the Nuget package here:

https://www.nuget.org/packages/randomtestvalues

And the repository here: https://github.com/RasicN/random-test-values

I hope you like it.

Example code:

var randomMyClass = RandomValue.Object<MyClass>();

Answer 6

Redgate makes a tool called SQL Data Generator. If you are willing to use a database as a seed for your testing objects, I think you'll find it is a pretty flexible tool.
