Project mention: Bogus custom Dataset | dev.to | 2024-01-06

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

  11 3,259 4.6 C#

  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.

Project mention: What am I missing about interfaces? | /r/csharp | 2023-11-23

a. you might do so purely out of argo cult, i.e. because someone told you this was the right thing to do™, and that's a silly exercise. b. you could also be doing this for a good reason: to use the interface with a mocking tool like NSubstitute

Project mention: Mock heavy tests | /r/dotnet | 2023-06-01

I'd say that without wanting to refactor the code a little bit (maybe moving those HttpClients into a service so that they are easily mocked) your best bet would be to use something like WireMock or MockHttp.

  1 1,469 8.6 C#
