Starts server, waits for URL, then runs test command; when the tests end, shuts down server
Requires Node version 6 or above.
npm install --save-dev start-server-and-test
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
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
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"
}
}
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
To see diagnostic messages, run with environment variable DEBUG=start-server-and-test
