help you fix your problem portfinder, which is a subdependency of Ember CLI, released a new version 1.0.22 a few hours ago (August 17, 2019). That one breaks ember serve. You will see a port in use error for all ports.
If you are unsure which version of portfinder is used in your project, you could run yarn why portfinder or npm list | grep portfinder.
code :
"resolutions": {
  "ember-cli/portfinder": "1.0.21"
}

fixed the issue. Will look into that further This can be fixed by replacing "ember-cli-esnext": "0.1.1" with "ember-cli-6to5": "0.2.1" in your package.json file and then run npm install.
Alternatively, you can also upgrade to ember-cli 0.1.7 following these upgrade instructions.

With these it helps After a lot of research and without a way to do it with built-in functionality, I decided to use ember-cli-dotenv.
I added a git-ignored .env file with IS_LOCAL = true for my local and IS_LOCAL = false in my development/staging/production environments that are in the servers.

may help you . You can do it the other way around: while running normally with ember serve (in development mode) simply visit http://localhost:4200/tests and you'll be running the same tests. You don't get the same test control through the console though.
Is there any difference in the dist/ folder generated when ember build vs ember serve?

it helps some times No difference. It's same unless you specify environment flag. Both ember build and ember server if you didn't specify --environment flag (possible values are development,production) by default it will build for development environment.
