如何配置mocha以打印错误的完整堆栈跟踪？

Question

我使用mocha在Typescript中运行以下测试：

Mocha命令：

$ mocha -r ts-node/register -r test/config.ts --timeout 10000 --async-stack-traces --full-trace 'test/**/*.test.ts'

测试：

import assert from "assert";
import { StatusCodes } from "http-status-codes";

describe.only("My test", () => {

    it("should work properly", async () => {
        const response = await client.postArticle(testArticle);
            
        assert.strictEqual(response.status, StatusCodes.OK);
        // More test code
    });
});

import axios from "axios";

async postArticle(testArticle: any): Promise<any> {
    return axios.post(resourceByIdUrl, testArticle, {
        headers: { Authorization: `Bearer ${myToken}` }
    });
}

在断言之前测试就已经失败了，在postArticle函数内部抛出一个错误。我的问题是，它没有告诉我导致错误的代码行：

Error: Request failed with status code 401
      at createError (/.../node_modules/axios/lib/core/createError.js:16:15)
      at settle (/.../node_modules/axios/lib/core/settle.js:17:12)
      at IncomingMessage.handleStreamEnd (/.../node_modules/axios/lib/adapters/http.js:244:11)
      at IncomingMessage.emit (node:events:341:22)
      at IncomingMessage.EventEmitter.emit (node:domain:467:12)
      at endReadableNT (node:internal/streams/readable:1294:12)
      at processTicksAndRejections (node:internal/process/task_queues:80:21)

特别是在更复杂的测试中，知道哪行代码导致了错误将非常有帮助。如何配置mocha以显示此行？

问题不在于摩卡，而在于axios。请参见导致截断堆栈跟踪的this issue。
