It seems like the only way to get jest to run in without watch mode is to run it with --coverage or set the environment variable to CI=true. Running npm test -- --watch=false (and similar) does not work.
My use case for this feature is debugging within VS Code through react scripts.
The following launch configuration was given in the create-react-app docs
{
"version": "0.2.0",
"configurations": [
{
"name": "Debug CRA Tests",
"type": "node",
"request": "launch",
"runtimeExecutable": "${workspaceRoot}/node_modules/.bin/react-scripts",
"args": [
"test",
"--runInBand",
"--no-cache"
],
"cwd": "${workspaceRoot}",
"protocol": "inspector",
"console": "integratedTerminal",
"internalConsoleOptions": "neverOpen"
}
]
}This somewhat works but it does not break at breakpoints because (I think) react-scripts is runs jest in watch mode. Adding "env": { "CI": "true" }, allows breakpoints to work again because it disables watch mode.

"type": "node",
"request": "launch",
"env": { "CI": "true" }, // this makes breakpoints work

"args": ["test", "--runInBand", "--no-cache"],
"cwd": "${workspaceRoot}",
"protocol": "inspector",
"console": "integratedTerminal",
"internalConsoleOptions": "neverOpen"
}
]
}
I'm fine with this workaround but I'd happier with a --watch=false, --no-watch, --single, or similar flag.
Thanks for the amazing tool and I apologize if I missed anything!
