我想要三个连接的 docker 容器（在构建服务器上运行它）：
- 我的应用程序（名称：app）
- 浏览器（在本例中为 chrome；名称：selenium）
- 我的 End2End/UI 测试（名称测试员）
但是测试没有运行。来自测试器容器的当前错误消息是“由于未知错误，请求失败，状态为 500：net::ERR_SSL_PROTOCOL_ERROR”
文件结构：
dir
test
specs
basic.js
app.js
docker-compose.yml
Dockerfile
package.json
wdio.conf.js
这里是我的文件：“docker-compose.yml”：

“测试/规范/basic.js”：
describe('test app', () => {
it('should have the right title', () => {

“app.js”：

app.get('/', (req, res) => res.send('<html><head><title>Hello</title></head><body>Hello World!</body></html>'));
const server = app.listen(3000, () => {

一些提示：
- 当我从测试仪或硒容器中调用 curl http://app:3000 时，我按预期收到了 HTML。
- 当我在测试中导航到谷歌时，我收到了谷歌代码
- 感谢您的时间！
