在 Deno 的 assertThrowsAsync() 中，找到标准异常类型以测试特定异常

Question

在以下 Deno 测试片段中：

    await assertThrowsAsync(
      async (): Promise<void> => {
        for await (const entry of walk('./non-existent-directory')) {
          console.log(entry)
        }
      },
      NotFound,
      'No such file or directory'
    )

Deno 将类型和消息拼写到控制台 NotFound: No such file or directory (os error 2)

但是 NotFound 异常声明在哪里？当我运行使用 deno 1.0.5's standard testing library 剪断时，我得到 error: TS2304 [ERROR]: Cannot find name 'NotFound'.

Answer 1

可以通过 Deno.errors.

访问 Deno 特定错误

对于 NotFound 你应该使用：

await assertThrowsAsync(
  async (): Promise<void> => {
    for await (const entry of walk('./non-existent-directory')) {
      console.log(entry)
    }
  },
  Deno.errors.NotFound,
  'No such file or directory'
)

完整列表如下：

Deno.errors.NotFound
Deno.errors.PermissionDenied
Deno.errors.ConnectionRefused
Deno.errors.ConnectionReset
Deno.errors.ConnectionAborted
Deno.errors.NotConnected
Deno.errors.AddrInUse
Deno.errors.AddrNotAvailable
Deno.errors.BrokenPipe
Deno.errors.AlreadyExists
Deno.errors.InvalidData
Deno.errors.TimedOut
Deno.errors.Interrupted
Deno.errors.WriteZero
Deno.errors.UnexpectedEof
Deno.errors.BadResource
Deno.errors.Http
Deno.errors.Busy

In Deno's assertThrowsAsync(), where are standard exception types found to test for specific exceptions
