Question

我似乎无法在我的fsunit测试中得到缩进。我一直被告知使用ML风格的“使用let ... in”，但这样做意味着编译器无法读取下一个测试的名称。有什么建议吗？

[<TestFixture>] 
module ``reading yaml files`` =
    let yamlReader = new yamlReader()
    let yamlConfig = yamlReader.read("./testFiles/config.yaml")

    [<Test>] ``should parse root property of a yaml file`` ()=
        yamlConfig.ContainsKey(new YamlScalar("token1")) |> should equal true
    [<Test>] ``should parse nested propery of a yaml file`` ()=
        let token1 = yamlConfig.[new YamlScalar("token1")] :?> YamlMapping
        let env3 = token1.[new YamlScalar("env3")] :?> YamlScalar
        env3.Value |> should equal "value3"
    [<Test>] ``should convert yamldocument to digestable format`` ()=
        let tokens = yamlReader.toTokens yamlConfig
        let firstToken = (Seq.head tokens)
        firstToken.name |> should equal "token2"

您缺少let关键字。试试这个：

[<TestFixture>] 
module ``reading yaml files`` =
    let yamlReader = new yamlReader()
    let yamlConfig = yamlReader.read("./testFiles/config.yaml")

    [<Test>] 
    let ``should parse root property of a yaml file`` ()=
        yamlConfig.ContainsKey(new YamlScalar("token1")) |> should equal true
    [<Test>] 
    let ``should parse nested propery of a yaml file`` ()=
        let token1 = yamlConfig.[new YamlScalar("token1")] :?> YamlMapping
        let env3 = token1.[new YamlScalar("env3")] :?> YamlScalar
        env3.Value |> should equal "value3"
    [<Test>] 
    let ``should convert yamldocument to digestable format`` ()=
        let tokens = yamlReader.toTokens yamlConfig
        let firstToken = (Seq.head tokens)
        firstToken.name |> should equal "token2"

Gustavo的版本是更好的版本（以及我通常使用的版本），但是如果你不想将[<Test>]放在一个单独的行上：

[<TestFixture>] 
module ``reading yaml files`` =
    let yamlReader = new yamlReader()
    let yamlConfig = yamlReader.read("./testFiles/config.yaml")

    let [<Test>] ``should parse root property of a yaml file`` () =
        yamlConfig.ContainsKey(new YamlScalar("token1")) |> should equal true

    let [<Test>] ``should parse nested propery of a yaml file`` () =
        let token1 = yamlConfig.[new YamlScalar("token1")] :?> YamlMapping
        let env3 = token1.[new YamlScalar("env3")] :?> YamlScalar
        env3.Value |> should equal "value3"

    let [<Test>] ``should convert yamldocument to digestable format`` () =
        let tokens = yamlReader.toTokens yamlConfig
        let firstToken = (Seq.head tokens)
        firstToken.name |> should equal "token2"
