What is FsUnitTyped?
FsUnitTyped is a statically typed set of FsUnit operators that makes
unit-testing with FsUnit even more safe and enjoyable (available only for NUnit and xUnit).
No more untyped constraints and tests like
1 |> should equal "1"
FsUnitTyped from NuGet
FsUnit.Typed is part of FsUnit package and can be installed from NuGet.
Syntax
With FsUnitTyped, you can write unit tests like this:
open FsUnitTyped
One object equals or does not equal another:
1 |> shouldEqual 1
1 |> shouldNotEqual 2
One comparable value greater or smaller than another:
11 |> shouldBeGreaterThan 10
10 |> shouldBeSmallerThan 11
A string contains specified substring:
"ships" |> shouldContainText "hip"
A List, Seq, or Array instance contains, does not contain a value or empty:
[1] |> shouldContain 1
[] |> shouldNotContain 1
[] |> shouldBeEmpty
A List or Array instance has a certain length:
[|1;2;3;4|] |> shouldHaveLength 4
A function should throw a certain type of exception:
(fun _ -> failwith "BOOM!") |> shouldFail<System.Exception>
A function should fail
shouldFail (fun _ -> 5/0 |> ignore)
