start-server-and-test

Starts server, waits for URL, then runs test command; when the tests end, shuts down server

NPM

Build status semantic-release js-standard-style renovate-app badge

Install

Requires Node version 6 or above.

npm install --save-dev start-server-and-test

Use

This command is meant to be used with NPM script commands. If you have a "start server", and "test" script names for example, you can start the server, wait for a url to respond, then run tests. When the test process exits, the server is shut down.

{
    "scripts": {
        "start-server": "npm start",
        "test": "mocha e2e-spec.js",
        "ci": "start-server-and-test start-server http://localhost:8080 test"
    }
}

To execute all tests simply run npm run ci

Alias

You can use either start-server-and-test, server-test or start-test commands in your scripts.

You can use : in front of port number like server-test :8080, so all these are equivalent

start-server-and-test start http://localhost:8080 test
server-test start http://localhost:8080 test
server-test http://localhost:8080 test
start-test :8080 test
start-test 8080 test
start-test 8080

Options

If you use convention and name your scripts "start" and "test" you can simply provide URL

{
    "scripts": {
        "start": "npm start",
        "test": "mocha e2e-spec.js",
        "ci": "start-server-and-test http://localhost:8080"
    }
}

You can also shorten local url to just port, the code below is equivalent to checking http://localhost:8080.

{
    "scripts": {
        "start": "npm start",
        "test": "mocha e2e-spec.js",
        "ci": "server-test 8080"
    }
}

You can provide first start command, port (or url) and implicit test command

{
    "scripts": {
        "start-it": "npm start",
        "test": "mocha e2e-spec.js",
        "ci": "server-test start-it 8080"
    }
}

You can provide port number and custom test command, in that case npm start is assumed to start the server.

{
    "scripts": {
        "start": "npm start",
        "test-it": "mocha e2e-spec.js",
        "ci": "server-test :9000 test-it"
    }
}

You can provide multiple resources to wait on, separated by a pipe |. (be sure to wrap in quotes)

{
    "scripts": {
        "start": "npm start",
        "test-it": "mocha e2e-spec.js",
        "ci": "server-test \"8080|http://foo.com\""
    }
}

Note for webpack-dev-server users

If you are using webpack-dev-server (directly or via angular/cli or other boilerplates) then please use the following URL form to check

start-server-and-test http-get://localhost:8080

This is because under the hood this module uses wait-on to ping the server. Wait-on uses HEAD by default, but webpack-dev-server does not respond to HEAD only to GET requests. Thus you need to use http-get:// URL format to force wait-on to use GET probe.

You can even wait on the bundle JavaScript url instead of the page url, see discussion in this issue #4

Debugging

To see diagnostic messages, run with environment variable DEBUG=start-server-and-test

Disable HTTPS certificate checks

To see disable HTTPS checks for wait-on, run with environment variable START_SERVER_AND_TEST_INSECURE=1.
