如何解决Micronaut gradle 测试不工作，说每个端口都已经绑定
我将 Micronaut 与 kotlin 结合使用，并使用 groovy 和 Spock 框架进行测试。
我现在正在为这个项目实施第一个单元测试。
每当我尝试运行 gradle 任务“test”或我创建的另一个任务“intTest”时，我总是收到错误消息，指出端口已在使用中。无论我尝试使用什么端口。
如果我使用相同的端口启动应用程序，它就可以工作。停止应用程序，运行测试 -> 不起作用。
我不知所措。

void 'test it works'() {

restUtils.getOwnClinician("test")

}

解决方法
错误消息清楚地表明端口已被使用，我建议使用 application-test.yml 中的以下属性在随机端口上运行测试
server:
host: localhost
port: -1
如果多个服务器同时在同一端口上启动，则设置显式端口可能会导致测试失败。为防止出现这种情况，请在测试环境配置中指定一个随机端口。
,首先，我显然犯了一个错误，将@MicronautTest 注释放在测试类的父类上。 micronaut好像不支持这个，当我把注解移到测试类本身时，端口绑定错误就消失了。
此后，当我尝试运行 intTest 任务时，每个请求都返回 401 响应。我只能通过将集成测试放在测试源集上来修复它，而不是我想要的 intTest 源集。
看来在 micronaut 中配置新的源集相当困难，所以我打算放弃这个想法，因为我不想在上面浪费更多时间。我仍然很好奇是否可能，所以如果你能够做到，请发表评论！ :)
