Question

好的，所以我正在看FsUnit为一些F＃代码开发测试，我正在查看GitHub上的示例BowlingGame.fsx。

进行第一次测试：

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

我在编译错误的情况下得到一个红色波浪形：

The value or constructor 'should' is not defined

有什么建议吗？

编辑：下面添加了完整的源代码。

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)

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>]

也许你引用了错误版本的FsUnit，与你选择的框架不兼容？删除对FsUnit的引用，然后使用NuGet再次添加它。

FsUnit - 未定义值或构造函数“should”
