ReactApp doesn't let test to exit

[tsuf239]

I tried this:

bring ex;

let website = new ex.ReactApp(
  projectPath: "../raffle-client",
   buildDir: "/dist",
  localPort: 5173,
  startCommand: "npm run dev",
);

test {
   assert(1 + 1 == 2);
}

This happened:

The test run completely but doesn't exit the process (ctrl+c is needed)

I expected this:

to run and exit

Is there a workaround?

ctrl+c

Anything else?
