Expecto Test in F # always passes, even if it fails

Question

I am trying to start and run in our test project.

Although it compiles and works fine, I just wanted to make sure that it really works. So I gave him a case of failure, and he passed.

Am I missing something stupid here?

My test setup

let tests =
    testList "Test Group" [
        test "Testing fail test" {
           let result = false
           Expecto.Expect.isTrue result 
        }
    ]

let runTests args =
  runTestsWithArgs defaultConfig args tests

Quit Test
