F# 在单元测试中调用异步函数时，任务是否立即取消？

我正在努力弄清楚为什么我的任务被取消了

[<Fact>]
let ``Query applicant count``() =

    async {

        // Test
        let! response = WebGateway.get EventStore.endpoint "ApplicantCountFn" // Can't get beyond this

        // Verify
        match! response.Content.ReadAsStringAsync()  |> Async.AwaitTask with
        | "" -> Assert.True (false, "result is empty")
        | _  -> ()
    }

附录：

let get baseAddress (resource:string) =

    async {
        let client = httpClient baseAddress
        return! client.GetAsync(resource) |> Async.AwaitTask
    }

我将客户端请求的超时时间增加到30秒：

let client = new HttpClient(handler)
client.Timeout     <- TimeSpan(0,0,30)

let client=新的HttpClient（处理程序）
客户端超时
let client = new HttpClient(handler)
client.Timeout     <- TimeSpan(0,0,30)
