Setting up Continuous Integration of Protractor using Jenkins - selenium

Question

I am writing automation test scripts using Protractor and now I need to set up the CI for this using Jenkins.
Tasks it needs to perform are:
Starting the selenium standalon server.
Starting the test using conf.js file.
Stopping the selenium standalone server.
Can anyone help in this regard?

Answer 1

I created a small bash script to do this.
# start selenium
./node_modules/protractor/bin/webdriver-manager start > /dev/null 2>&1 &
# wait until selenium is up
while ! curl http://localhost:4444/wd/hub/status &>/dev/null; do :; done
# run the build
grunt cibuild --force
# stop selenium
curl -s -L http://localhost:4444/selenium-server/driver?cmd=shutDownSeleniumServer > /dev/null 2>&1
This script is invoked from a free-style project in jenkins (Build > Execute shell)
Then the test result report is generated by reading the protractor test results. Hence, you have to produce junit reports from protractor, (look here) :
onPrepare: function() {
// The require statement must be down here, since jasmine-reporters
// needs jasmine to be in the global and protractor does not guarantee
// this until inside the onPrepare function.
require('jasmine-reporters');
jasmine.getEnv().addReporter(
new jasmine.JUnitXmlReporter('xmloutput', true, true));
},
To make the report visible in jenkins i add a post build action in the job: Publish JUnit test result report:

Alternatively, you could run this as a Grunt Task. First install grunt on Jenkins. Install the NPM packages for protractor_webdriver and protractor. Setup the configuration file to point the the node_module path and config file paths.

Then install protractor node modules. The Gruntfile would look similar to this. I created a test directory where the conf and spec files would be located.
module.exports = function (grunt) {
grunt.initConfig({
protractor_webdriver: {
your_target: {
options: {
path: 'node_modules/protractor/bin/',
command: 'webdriver-manager start'
}
}
},
protractor: {
options: {
configFile: "node_modules/protractor/referenceConf.js", // Default config file
keepAlive: true, // If false, the grunt process stops when the test fails.
noColor: false, // If true, protractor will not use colors in its output.
args: {
// Arguments passed to the command
}
},
your_target: {
options: {
configFile: "test/conf.js", // Target-specific config file
args: {} // Target-specific arguments
}
}
}
});
grunt.registerTask('p:test', [
'protractor_webdriver',
'protractor'
]);
});

The newest protractor allows you to run the selenium standalone server directly from the conf.js (or whatever protractor entry point you have).
comment out (or delete) the seleniumAddress: 'http://localhost:4444/wd/hub', line, and replace it with seleniumServerJar: './node_modules/protractor/selenium/latest.jar'.
latest.jar isn't installed by default, I created it as a symlink to the latest version installed via npm install protractor --save. This gives longer life to my conf.js files in the same directory.
Within the ./node_modules/protractor/selenium/ folder I ran ln -s selenium-server-standalone-2.48.2.jar latest.jar

You can use Gulp which is far simpler.
After installing gulp in Jenkins System , you may install the npm dependencies(npm install) & run gulp tasks directly as windows batch command in Jenkins as below:
In the background to make selenium server up and running and providing various other parameters , you may use packages like 'gulp-angular-protractor' in the gulpfile.js as below:
gulpfile.js
'use strict';
var gulp = require('gulp'),
gulpProtractorAngular = require('gulp-angular-protractor'),
gulpStart = gulp.Gulp.prototype.start,
currentStartTaskName;
gulp.Gulp.prototype.start = function (task) {
currentStartTaskName = task;
gulpStart.apply(this, arguments);
};
function executeWebTests(suiteName, appName) {
return gulp.src([])
.pipe(gulpProtractorAngular({
'configFile': './conf.js',
'debug': false,
'autoStartStopServer': true,
args: [
'--suite', suiteName,
'--capabilities.browserName', 'chrome',
'--params.APPNAME', appName,
'--params.SUITENAME', currentStartTaskName,
'--capabilities.platformName', 'Windows'],
keepAlive: false
}))
.on('error', function (e) {
console.log('Ended with below ERROR::',e);
process.exit(1);
})
.on('end', function () {
console.log('Test complete');
process.exit();
});
}
gulp.task('RegressionSuiteTask', function () {
executeWebTests('regressionTests,','Application_Name');
});
conf.js
suites: {
regressionTests: ['testCases/**/*.js']//will run all specs in subfolders
},

I know this already resolved and want to target for beginner to create Jenkins job and running test. I suggest to use selenium-server-standalone jar in configuration file and call configuration file from Jenkins.
conf.js
..
exports.config = {
//seleniumAddress: 'http://localhost:4444/wd/hub',
seleniumServerJar: 'node_modules/protractor/node_modules/webdriver-manager/selenium/selenium-server-standalone-3.5.3.jar',
....
//html reporter logic
.....
Creating Jenkins Job
Install node js on Jenkins Server
Install Html Publisher Plugin for end to end testing report
Create Freestyle Project or whatever your needs
Go to Build Section -> Add build step and choose Execute Windows
batch command if Jenkins server in Windows otherwise choose Execute
Shell for Linux
Call conf.js (install packages and call your configuration file)
For reporting Got to Post-Build Actions Section -> Add Publish Html
Reports and call your report file (file assuming from root of your
project)
However you can customize execution command using gulp or similar other packages. Thanks
