Configuring SpecFlow for XUnit using new-style csproj

Configuring SpecFlow for XUnit using new-style csproj

[This post is now obsolete - you should look at updating to later versions of SpecFlow]

While you cannot yet use SpecFlow with netcore or netstandard projects, you can use new-style (dotnet) test projects that target net461, and reference netstandard projects-under-test from there.

We like to use XUnit as the underlying test provider in this scenario, and we do the following:

  1. Install the current SpecFlow VS 2017 extension into VS 2017
  2. Create a DotNetCore XUnit test project and perform any package updates offered to you (this handily sets up the VS2017 test environment properly)
  3. Change the <TargetFramework> in the .csproj file from dotnetcore2.x to net461 (or 462, or whatever, but 461 is a good safe lowest common denominator for most scenarios)
  4. Add the SpecFlow.XUnit package to your project
  5. Add an app.config file to configure XUnit code generation

You can now add feature files and generate steps in the normal way.

If you use Azure Functions on a regular basis, you'll likely have grappled with the challenge of testing them. Even now, several years after their introduction, the testing story for Functions is not hugely well defined. In the first of a series of posts, we look at some different approaches to testing your functions apps, and introduce the Corvus.Testing library.
