(source) 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.
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.
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.
If specified, error
can be a Class
, RegExp
, or a validation function. See {@link throws} for more details.
Besides the async nature to await the completion behaves identically to {@link doesNotThrow}.
import assert from 'node:assert/strict';
await assert.doesNotReject(
async () => {
throw new TypeError('Wrong value');
},
SyntaxError,
);
import assert from 'node:assert/strict';
assert.doesNotReject(Promise.reject(new TypeError('Wrong value')))
.then(() => {
// ...
});
