运行 使用 jest @nestjs 进行端到端测试

(node:1500) UnhandledPromiseRejectionWarning: TypeError: Caught error after test environment was torn down
ExpressAdapter is not a constructor
(node:1500) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2)
(node:1500) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
Jest did not exit one second after the test run has completed.
This usually means that there are asynchronous operations that weren't stopped in your tests. Consider running Jest with `--detectOpenHandles` to troubleshoot this issue.

我遇到了同样的错误，并通过仅将 ts 文件（实体）传递到我的 typeorm 测试环境来修复它。
例如：
module.exports = {

port: DB_PORT,
username: DB_USERNAME,
password: DB_PASSWORD,
database: DB_DATABASE,
migrations: ['**/migrations/*.{ts,js}'],
