start-server-and-test not starting test cases after starting the test server

Question

I am trying to use start-server-and-test npm package and want to run test cases. For this I first need to start a test server and then run test command. This how my package.json script part looks like.

Now the issue is start-server-and-test is starting the test server but it's not starting the test cases.

{
...
...
  "scripts": {
    "test": "jest --runInBand --config jest.config.json",
    "dev": "nodemon --watch 'src/**' --ext 'ts,js' --exec \"ts-node src/app.ts\"",
    "start": "ts-node src/app.ts",
    "test-server": "MYSQL_TABLE_PREFIX=TEST_ PORT=4001 ts-node src/app.ts",
    "ci": "start-server-and-test 'yarn test-server' http://localhost:4001/ 'yarn test'"
  },
...
...
}

Answer 1

So I figured out that the issue was my endpoint http://localhost:4001/ was not responding with 200 status code and due to this the command yarn test was not getting executed. So then I changed the endpoint to http://localhost:4001/health which was giving a 200 status code and then the test cases were getting executed.

so now the package.json looks like this

{
...
...
  "scripts": {
    "test": "jest --runInBand --config jest.config.json",
    "dev": "nodemon --watch 'src/**' --ext 'ts,js' --exec \"ts-node src/app.ts\"",
    "start": "ts-node src/app.ts",
    "test-server": "MYSQL_TABLE_PREFIX=TEST_ PORT=4001 ts-node src/app.ts",
    "ci": "start-server-and-test 'yarn test-server' http://localhost:4001/health 'yarn test'"
  },
...

}
