如何在Jest中模拟AbortController

npm install --save-dev jest

const { AbortController } = require('abort-controller');
const { fetchWithAbort } = require('./your-module');

test('should simulate AbortController in Jest', () => {
  const controller = new AbortController();
  const signal = controller.signal;

  // 调用需要测试的函数，并传递AbortSignal对象
  const result = fetchWithAbort(signal);

  // 进行断言或期望结果的验证
  expect(result).toBe('expected result');
});

function fetchWithAbort(signal) {
  return new Promise((resolve, reject) => {
    // 在请求中使用AbortSignal对象
    fetch('https://api.example.com/data', { signal })
      .then(response => response.json())
      .then(data => resolve(data))
      .catch(error => {
        if (signal.aborted) {
          reject(new Error('Request aborted'));
        } else {
          reject(error);
        }
      });
  });
}
