Tests vanish after being run

[ImaginaryDevelopment]

after running a single test, it vanishes

I have only two files after creating a new project targeting 4.6.2

module ConversionsTests

open Expecto

[<Tests>]
let focusedTests =
  testList "unfocused list" [
    ftestList "focused list" [
      testCase "will run" <| fun () -> Expect.equal (2+2) 4 "2+2"
      ftestCase "will run" <| fun () -> Expect.equal (2+2) 4 "2+2"
      test "will run" { Expect.equal (2+2) 4 "2+2" }
    ]
    testList "unfocused list" [
      testCase "skipped" <| fun () -> Expect.equal (2+2) 1 "2+2?"
      ftestCase "will run" <| fun () -> Expect.equal (2+2) 4 "2+2"
      test "skipped" { Expect.equal (2+2) 1 "2+2?" }
      ftest "will run" { Expect.equal (2+2) 4 "2+2" }
    ]
    testCase "skipped" <| fun () -> Expect.equal (2+2) 1 "2+2?"
  ]

and Program.fs

open System
open Expecto

let tests =
  test "A simple test" {
    let subject = "Hello World"
    Expect.equal subject "Hello World" "The strings should equal"
  }

[<EntryPoint>]
let main args =
  let result = runTestsWithArgs defaultConfig args tests
  Console.ReadLine() |> ignore
  result

if I rebuild the test project the test reappears.

I have the same issue.

[olivercoad]

This happens because you have multiple tests with the same fully qualified name: unfocussed list/focussed list/will run for example could refer to 3 different tests.

From the expecto readme:

You have to remember that the fully qualified names of tests need to be unique across your test project.

If you rename your tests to be unique it works as expected

Perhaps it could be improved by somehow notifying the user when they have non-unique test names. This would probably need some changes in expecto as well as expecto-adapter.

@olivercoad It is implemented in Expecto.
