Parameterized tests with TestCaseSource attribute not working

Description

I want to run parameterized test using the NUnit attribute TestCaseSource. Please tell me how to do that and add code examples for paremterized tests to the documentation on https://fsprojects.github.io/FsUnit/NUnit.html.

Repro steps

Run the code snippet

namespace FooSpace

module FooTests =
    
    open NUnit.Framework
    open FsUnit

    let mySrc1 = [|
            (17, "One", 1.5);
            (42, "Two", 2.3);
        |]

    let mySrc2 = [|
            [| (17, "One", 1.5) |];
            [| (42, "Two", 2.3) |];
        |]

    let mySrc3 = seq {
            yield (17, "One", 1.5)
            yield (42, "Two", 2.3)
        }

    [<Test>]
    [<TestCaseSource("mySrc1")>]
    let testFoo (testData: int * string * float) =
        let foo, bar, umu = testData
        1 |> should equal 1

Note that I tried different flavours of test case sources above, based on (rather old) search results from the web like, e.g.

Expected behavior

A dotnet test discovers two test cases, both are run and succeed.

Actual behavior

Two test cases are discovered and run, but both fail with the error message

Not enough arguments provided, provide at least 3 arguments.
  Exception doesn't have a stacktrace

no matter if one uses mySrc1, mySrc2 or mySrc3.

Known workarounds

None.

Okay. Well. Thanks for your help anyway. I’m closing this issue.

Ah, sorry. My fault. I only now saw the member keyword. I got it. The class is necessary. Let me try…
