Integration testing a Falco app?

[sfinnie]

Hi all

I want to add some integration tests for my exploratory Falco app. In particular, I'd like to check the responses returned from the HttpHandlers. I found this blog post useful, but am struggling with configuring the TestHost. My test currently reads:

open Microsoft.AspNetCore.Hosting
open NUnit.Framework
open FsUnit
open Microsoft.AspNetCore.TestHost

module ``Skeleton Tests`` =

    [<Test>]
    let ``Ensure NUnit and FsUnit are installed and working correctly`` () =
        let builder: IWebHostBuilder = WebHostBuilder()
                                           .ConfigureServices(FalcoFood.Program.configureServices)
                                           .Configure(Action<IApplicationBuilder> FalcoFood.Program.configureApp)
        let server = new TestServer(builder)
        let client = server.CreateClient()
        //...

For that to work, I need configureServices and configureApp functions in my app. As a dotnet & F# newbie, I'm struggling with what those should look like. The blog post uses Giraffe and it uses a different approach to configuration compared to Falco (I think).

My app doesn't inject any services and so I'm not sure what the configureServices / configureApp functions need to look like.

Any pointers appreciated. Thanks.
