assert.doesNotReject(asyncFn[, error][, message])

• asyncFn <Function> | <Promise>

• error <RegExp> | <Function>

• message <string>

等待 asyncFn promise，或者，如果 asyncFn 是函数，则立即调用该函数并等待返回的 promise 完成。然后会检查 promise 是否没有被拒绝。

¥Awaits the asyncFn promise or, if asyncFn is a function, immediately calls the function and awaits the returned promise to complete. It will then check that the promise is not rejected.

如果 asyncFn 是函数并且它同步抛出错误，则 assert.doesNotReject() 将返回使用使用该错误拒绝的 Promise。如果函数没有返回 promise，则 assert.doesNotReject() 将返回使用 ERR_INVALID_RETURN_VALUE 错误拒绝的 Promise。在这两种情况下，都会跳过错误句柄。

¥If asyncFn is a function and it throws an error synchronously, assert.doesNotReject() will return a rejected Promise with that error. If the function does not return a promise, assert.doesNotReject() will return a rejected Promise with an ERR_INVALID_RETURN_VALUE error. In both cases the error handler is skipped.

使用 assert.doesNotReject() 实际上没有用，因为捕获拒绝然后再次拒绝它几乎没有什么好处。相反，请考虑在特定代码路径旁边添加不应拒绝的注释，并尽可能使错误消息具有表现力。

¥Using assert.doesNotReject() is actually not useful because there is little benefit in catching a rejection and then rejecting it again. Instead, consider adding a comment next to the specific code path that should not reject and keep error messages as expressive as possible.

如果指定，则 error 可以是 Class、RegExp 或验证函数。有关详细信息，请参阅 assert.throws()。

¥If specified, error can be a Class, RegExp, or a validation function. See assert.throws() for more details.

除了等待完成的异步性质外，其行为与 assert.doesNotThrow() 相同。

¥Besides the async nature to await the completion behaves identically to assert.doesNotThrow().

import assert from 'node:assert/strict';

await assert.doesNotReject(
  async () => {
    throw new TypeError('Wrong value');
  },
  SyntaxError
);const assert = require('node:assert/strict');

(async () => {
  await assert.doesNotReject(
    async () => {
      throw new TypeError('Wrong value');
    },
    SyntaxError
  );
})();拷贝

import assert from 'node:assert/strict';

assert.doesNotReject(Promise.reject(new TypeError('Wrong value')))
  .then(() => {
    // ...
  });const assert = require('node:assert/strict');

assert.doesNotReject(Promise.reject(new TypeError('Wrong value')))
  .then(() => {
