Run web server and the selenium server with Gulp + nightwatch.js - selenium

Question

I'm trying to run some nightwatch.js e2e tests using Gulp.
At the moment I have to do the following:
Run the selenium server manually
Set the path of selenium-server-standalone-2.47.1.jar and phantomjs.exe
Run the web server manually
My gulp task looks as follows:
gulp.task("run-e2e-tests", function () {
return gulp.src('')
.pipe(nightwatch({
configFile: "nightwatch.json",
cliArgs: {
env: "phantomjs"
}
}));
});
My nightwatch.js configuration looks as follows:
{
"src_folders" : [
"bundle/e2e_test/"
],
"output_folder": false,
"selenium" : {
"start_process" : false,
"server_path" : "./selenium-binaries/selenium-server-standalone-2.47.1.jar"
},
"test_settings" : {
"default" : {
"silent": true,
"screenshots" : {
"enabled" : false
},
"desiredCapabilities": {
"browserName": "phantomjs",
"javascriptEnabled" : true,
"acceptSslCerts" : false
}
},
"phantomjs" : {
"desiredCapabilities": {
"browserName": "phantomjs",
"javascriptEnabled" : true,
"acceptSslCerts" : false,
"phantomjs.binary.path" : "phantomjs.exe"
}
},
"chrome" : {
"desiredCapabilities": {
"browserName": "chrome",
"javascriptEnabled": true,
"acceptSslCerts": false
}
}
}
}
If I change "start_process" to true I get the following error:
[17:10:04] Using gulpfile ~\Desktop\CPIC.UI.Web\gulpfile.js
[17:10:04] Starting 'run-e2e-tests'...
[17:10:04] log file

Connection refused! Is selenium server started?
[17:10:06] 'run-e2e-tests' errored after 1.5 s

Message:

The e2e test run as expected but I would like to run both the web server and the selenium server from Gulp automatically as part of my CI process.

I got it to work! Basically if you install selenium and phantomjs via npm something is wrong so you have to manually download them and set the paths int the nightwatch.js configuration file:
{
"src_folders" : [
"bundle/e2e_test/"
],
"output_folder": false,
"selenium" : {
"start_process" : true,
"server_path" : "./selenium-binaries/selenium-server-standalone-2.47.1.jar"
},
"test_settings" : {
"default" : {
"silent": true,
"screenshots" : {
"enabled" : false
},
"desiredCapabilities": {
"browserName": "phantomjs",
"javascriptEnabled" : true,
"acceptSslCerts" : false
}
},
"phantomjs" : {
"desiredCapabilities": {
"browserName": "phantomjs",
"javascriptEnabled" : true,
"acceptSslCerts" : false,
"phantomjs.binary.path" : "./selenium-binaries/phantomjs.exe"
}
}
}
}
To run the web server and kill it I used 3 tasks ans run-sequence:
gulp.task("run-e2e-tests", function (cb) {
runSequence(
"run-http-server",
"run-nightwatch",
"kill-http-server",
cb);
});
gulp.task("run-nightwatch", function () {
return gulp.src('')
.pipe(nightwatch({
configFile: "nightwatch.json",
cliArgs: {
env: "phantomjs"
}
}));
});
gulp.task("run-http-server", function () {
return connect.server({
port: 8888
});
});
gulp.task("kill-http-server", function () {
return connect.serverClose();
});
