FsUnit - 沒有定義值或構造函數'should'

Question

好吧，我正在查看FsUnit來開發一些F＃代碼的測試，並且我正在查看GitHub上的示例BowlingGame.fsx。

採取的第一個測試：

[<Test>] 
let ``with simple scores should get the expected score.``() = 
scoreBowls [1;2;3] |> should equal 6 

我得到一個紅色波浪下應與編譯器錯誤：

The value or constructor 'should' is not defined 

有什麼建議？

編輯：下面添加完整的源代碼。

module Calculations.UnitTests 

open NUnit.Framework 
open FsUnit 

let (|EndOfGame|IncompleteStrike|Strike|Normal|Other|) (l, frame) = 
    match l with 
    | _ when frame = 11   -> EndOfGame(0) 
    | [10;s]      -> IncompleteStrike(10+s+s) 
    | 10::s::n::tail    -> Strike(10+s+n, s::n::tail) 
    | f::s::n::tail when f+s = 10 -> Normal(f+s+n, n::tail) 
    | f::s::n::tail    -> Normal(f+s, n::tail) 
    | ls       -> Other(List.fold (+) 0 ls) 

let scoreBowls bowls = 
    let rec scoreBowls' frame l current_score = 
     let nextframe = scoreBowls' (frame+1) 
     match (l, frame) with 
     | EndOfGame(score)  -> current_score + score 
     | IncompleteStrike(score) -> current_score + score 
     | Strike(score, l)  -> nextframe l (current_score + score) 
     | Normal(score, l)  -> nextframe l (current_score + score) 
     | Other(score)   -> current_score + score 
    scoreBowls' 1 bowls 0 

[<Test>] 
let ``with simple scores should get the expected score.``() = 
    scoreBowls [1;2;3] |> should equal 6 

[<Test>] 
let ``with a spare should get the expected score (spare).``() = 
    scoreBowls [2;8;1] |> should equal 12 

[<Test>] 
let ``with a strike should get the expected score (strike).``() = 
    scoreBowls [10;1;2] |> should equal 16 

[<Test>] 
let ``that is perfect should get a score of 300.``() = 
    scoreBowls [for i in 1..18 -> 10] |> should equal 300 

[<Test>] 
let ``with spares in the last frame should get the expected score (spare in last frame).``() = 
    scoreBowls ([for i in 1..18 -> 0] @ [2;8;1]) |> should equal 11 

[<Test>] 
let ``with a strike in the last frame should get the expected score (strike in last frame).``() = 
    scoreBowls ([for i in 1..18 -> 0] @ [10;10;1]) |> should equal 21 

[<Test>] 
let ``with double strikes should add the score of the first strike to the score of the second.`` () = 
    scoreBowls [10;10;1] |> should equal 33 

[<Test>] 
let ``that looks like an average bowler's game should get the expected score (example game).``() = 
    scoreBowls [1;4;4;5;6;4;5;5;10;0;1;7;3;6;4;10;2;8;6] |> should equal 133

也許您引用了錯誤版本的FsUnit，與您選擇的框架不兼容？刪除對FsUnit的引用並使用NuGet再次添加它。
