Spectron testing producing a JScript syntax error - json

I'm trying to test out spectron for electron in terms of testing but as I'm going through a tutorial, I keep getting this error message whenever I run npm run test:e2e. My test file syntactically correct but im not sure why i run into an error through compilation
Specs:
Nodejs 6.10.3
Electron 1.6.1
here's the error message
here's the json file package.json
{
"name": "your-app",
"version": "0.1.0",
"main": "main.js",
"scripts": {
"start": "C:/Users/Livs/Documents/imdc/logger/node_modules/.bin/electron .",
"test:e2e": "C:/Users/Livs/Documents/imdc/logger/test.js"
},
"devDependencies": {
"electron-chromedriver": "^1.7.1",
"electron-prebuilt": "^1.4.13",
"electron-rebuild": "^1.5.11",
"chai": "^3.5.0",
"chai-as-promised": "^5.3.0",
"electron": "^1.3.4",
"mocha": "^3.0.2",
"spectron": "^3.4.0"
}
}
Heres the testing file test.js
const Application = require('spectron').Application;
const path = require('path');
const chai = require('chai');
const chaiAsPromised = require('chai-as-promised');
var electronPath = path.join(__dirname, '..', 'node_modules', '.bin', 'electron');
if (process.platform === 'win32') {
electronPath += '.cmd';
}
var appPath = path.join(__dirname, '..');
var app = new Application({
path: electronPath,
args: [appPath]
});

Your npm run e2e just calls the test.js file. You'll need a test runner, mocha for instance. Then you would run mocha test.js. Or change the e2e script inside package.json to run that command.
All your file paths for the scripts inside package.json should be relative to the package root, ie logger/test.js. Regarding the npm bins you only need to type the bin name, ie electron.
To solve your problem you should change your package.json test:e2e command to mocha test.js.
(You can also change your start command to electron . since custom npm commands will always look for binaries in ./node_modules/.bin

nodeJS development and production environment config file loading

Based on this answer here https://stackoverflow.com/a/22524056/777700 I have set exactly the same configuration options, but it doesn't work.
My (partial) app.js file:
console.log('environment: '+process.env.NODE_ENV);
const config = require('./config/db.json')[process.env.NODE_ENV || "development"];
console.log(config);
My ./config/db.json file:
{
"development":{
"host":"localhost",
"port":"3306",
"username":"root",
"password":"",
"database":"dbname"
},
"production":{
"host":"production-host",
"port":"3306",
"username":"user",
"password":"pwd",
"database":"dbname"
}
}
Console.log outputs:
environment: development
undefined
and app crashes. Any idea why? File is there, if I remove the [...] part of require(), it does print out the db.json file, with it, it prints out undefined.
EDIT
I tried to add console.log(typeof config) just after require() to see what I'm getting and I have noticed that if I require('./config/db.json')[process.env.NODE_ENV] I get undefined, but if I require('./config/db.json')["development"] I get back proper object.
Versions:
nodeJS 6.11.4
express 4.16.2
After more debugging and searching online, I have finally found the solution. The problem is that I'm on Windows machine and I was using npm run dev command while my "dev" command looked like SET NODE_ENV=development && nodemon server.js.
Experienced eye will notice a space before &&, which added a space behind the variable development, so the variable I was comparing against was "development " and not "development" as I was thinking.
So, the original answer from other question does work and it does load proper config!
You should export configuration as a variable:
const config = {
"development":{
"host":"localhost",
"port":"3306",
"username":"root",
"password":"",
"database":"dbname"
},
"production":{
"host":"production-host",
"port":"3306",
"username":"user",
"password":"pwd",
"database":"dbname"
}
};
module.exports = config;
This way it will be found :)
If you want to do it via JSON:
const fs = require('fs')
let localConfig
try {
localConfig = JSON.parse((fs.readFileSync('./config/db.json', 'utf-8'))
} catch (e) {
console.log('Could not parse local config.')
localConfig = false
}
module.exports = localConfig
You could then add logic for production, if there's no local configuration localConfig will return false and you can look for environment variables injected at that point.
Update:
I see that you're giving the production config yourself, in that case you can just access the key you need based on the environment. Just import localConfig and use the keys you need.
Its better to use dotenv package for this
npm i dotenv
Step 1: In package.json add this
"scripts": {
"start": "nodemon app.js",
"dev": "NODE_ENV=dev nodemon app.js"
"prod": "NODE_ENV=prod nodemon app.js"
},
Step 2: Add .env.prod and .env.dev files
.env.dev
PORT=7200
# Set your database/API connection information here
DB_URI=localhost
DB_USERNAME=root
DB_PASSWORD=password
DB_DEFAULT=dbName
Step 3: Add this in config.js
const dotenv = require('dotenv').config({ path: `.env.${process.env.NODE_ENV}` });
const result = dotenv;
if (result.error) {
throw result.error;
}
const { parsed: envs } = result;
// console.log(envs);
module.exports = envs;
Step 4: Use like this when needed
const {
DB_URI, DB_USERNAME, DB_PASSWORD, DB_DEFAULT,
} = require('../config');
Now if u want for development, run
npm run dev
For prod, use
npm run prod

How to use Polymer for live-reloading of code

I am using Polymer and reloading changes in files manually. So I tried using using browser-sync and also browser-sync with gulp but not able to succeed.
I tried two following ways :
1) npm scripts in package.json
"scripts": {
"dev": "polymer serve | npm run watch",
"watch": "browser-sync start --proxy localhost:8080 --files 'src/*.html, src/*.js, images/*' "
},
Running it using npm run dev ,it ran but not able to detect the changes in the file.
2) Using gulp with browser-sync
var gulp = require('gulp');
var bs = require('browser-sync').create();
gulp.task('browser-sync', function() {
bs.init({
port : 5000,
proxy: {
target : "localhost:8080"
}
});
});
gulp.task('watch', ['browser-sync'], function () {
gulp.watch("*.html").on('change', bs.reload);
});
It also ran but not able to detect the changes in *.html file which is present in src folder.
Can anybody help me why changes of files not being detected.
I figured it myself, i was doing one small mistake in npm scripts. I have modified as :
"scripts": {
"dev": "polymer serve --port 8081 | npm run watch",
"test": "polymer test",
"watch": "browser-sync start --proxy localhost:8081 --files \"src/**/*.*, index.html, *.js\""
},
Now it is working fine !!

"readme": "# selenium-webdriver\n\nSelenium is a browser automation library. Most often used for testing\nweb-applications, Selenium may be used for any task that requires automating\ninteraction with the browser.\n\n## Installation\n\nSelenium supports Node `0.12.x` and `4.x`. Users on Node `0.12.x` must run with\nthe --harmony flag. Selenium may be installed via npm with\n\n npm install selenium-webdriver\n\nOut of the box, Selenium includes everything you need to work with Firefox. You\nwill need to download additional components to work with the other major\nbrowsers. The drivers for Chrome, IE, PhantomJS, and Opera are all standalone\nexecutables that should be placed on your\n[PATH](http://en.wikipedia.org/wiki/PATH_%28variable%29). The SafariDriver\nbrowser extension should be installed in your browser before using Selenium; we\nrecommend disabling the extension when using the browser without Selenium or\ninstalling the extension in a profile only used for testing.\n\n| Browser | Component |\n| ----------------- | ---------------------------------- |\n| Chrome | [chromedriver(.exe)][chrome] |\n| Internet Explorer | [IEDriverServer.exe][release] |\n| PhantomJS | [phantomjs(.exe)][phantomjs] |\n| Opera | [operadriver(.exe)][opera] |\n| Safari | [SafariDriver.safariextz][release] |\n\n## Usage\n\nThe sample below and others are included in the `example` directory. You may\nalso find the tests for selenium-webdriver informative.\n\n var webdriver = require('selenium-webdriver'),\n By = require('selenium-webdriver').By,\n until = require('selenium-webdriver').until;\n\n var driver = new webdriver.Builder()\n .forBrowser('firefox')\n .build();\n\n driver.get('http://www.google.com/ncr');\n driver.findElement(By.name('q')).sendKeys('webdriver');\n driver.findElement(By.name('btnG')).click();\n driver.wait(until.titleIs('webdriver - Google Search'), 1000);\n driver.quit();\n\n### Using the Builder API\n\nThe `Builder` class is your one-stop shop for configuring new WebDriver\ninstances. Rather than clutter your code with branches for the various browsers,\nthe builder lets you set all options in one flow. When you call\n`Builder#build()`, all options irrelevant to the selected browser are dropped:\n\n var webdriver = require('selenium-webdriver'),\n chrome = require('selenium-webdriver/chrome'),\n firefox = require('selenium-webdriver/firefox');\n\n var driver = new webdriver.Builder()\n .forBrowser('firefox')\n .setChromeOptions(/* ... */)\n .setFirefoxOptions(/* ... */)\n .build();\n\nWhy would you want to configure options irrelevant to the target browser? The\n`Builder`'s API defines your _default_ configuration. You can change the target\nbrowser at runtime through the `SELENIUM_BROWSER` environment variable. For\nexample, the `example/google_search.js` script is configured to run against\nFirefox. You can run the example against other browsers just by changing the\nruntime environment\n\n # cd node_modules/selenium-webdriver\n node example/google_search\n SELENIUM_BROWSER=chrome node example/google_search\n SELENIUM_BROWSER=safari node example/google_search\n\n### The Standalone Selenium Server\n\nThe standalone Selenium Server acts as a proxy between your script and the\nbrowser-specific drivers. The server may be used when running locally, but it's\nnot recommend as it introduces an extra hop for each request and will slow\nthings down. The server is required, however, to use a browser on a remote host\n(most browser drivers, like the IEDriverServer, do not accept remote\nconnections).\n\nTo use the Selenium Server, you will need to install the\n[JDK](http://www.oracle.com/technetwork/java/javase/downloads/index.html) and\ndownload the latest server from [Selenium][release]. Once downloaded, run the\nserver with\n\n java -jar selenium-server-standalone-2.45.0.jar\n\nYou may configure your tests to run against a remote server through the Builder\nAPI:\n\n var driver = new webdriver.Builder()\n .forBrowser('firefox')\n .usingServer('http://localhost:4444/wd/hub')\n .build();\n\nOr change the Builder's configuration at runtime with the `SELENIUM_REMOTE_URL`\nenvironment variable:\n\n SELENIUM_REMOTE_URL=\"http://localhost:4444/wd/hub\" node script.js\n\nYou can experiment with these options using the `example/google_search.js`\nscript provided with `selenium-webdriver`.\n\n## Documentation\n\nAPI documentation is included in the `docs` directory and is also available\nonline from the [Selenium project][api]. Addition resources include\n\n- the #selenium channel on freenode IRC\n- the [selenium-users#googlegroups.com][users] list\n- [SeleniumHQ](http://www.seleniumhq.org/docs/) documentation\n\n## Contributing\n\nContributions are accepted either through [GitHub][gh] pull requests or patches\nvia the [Selenium issue tracker][issues]. You must sign our\n[Contributor License Agreement][cla] before your changes will be accepted.\n\n## Issues\n\nPlease report any issues using the [Selenium issue tracker][issues]. When using\nthe issue tracker\n\n- __Do__ include a detailed description of the problem.\n- __Do__ include a link to a [gist](http://gist.github.com/) with any\n interesting stack traces/logs (you may also attach these directly to the bug\n report).\n- __Do__ include a [reduced test case][reduction].

it is a spring boot project. it uses gulp. the project is not needed to be up to run the protractor.
Remove & reinstall npm, gulp, nodejs.
Could you please update the gulp-protractor-qa plugin. Mean while i hope you are using gulp-protractor update that also.
Update gulp-protractor to version 3.0.0
npm update gulp-protractor & give a try it should work.

Gulp doesn't work on Ubuntu 16.04 [duplicate]

As shown in the screen shot below I am not able to run gulp to concat the JavaScript files. Its saying that gulp is not defined.
I have tried the following commands:
npm install -g gulp
npm install gulp
npm install gulp --save-dev
I have also set the environment variables as following:
C:\Users\<user>\AppData\Roaming\npm;C:\Python27;C:\Users\<user>\AppData\Roaming\npm\node_modules;C:\Users\<user>\AppData\Roaming\npm\node_modules\gulp;
var concat = require('gulp-concat');
var rename = require('gulp-rename');
var uglify = require('gulp-uglify');
//script paths
var jsFiles = 'scripts/*.js',
jsDest = 'dist/scripts';
gulp.task('scripts', function() {
return gulp.src(jsFiles)
.pipe(concat('scripts.js'))
.pipe(gulp.dest(jsDest));
});
you just need to install and require gulp locally, you probably only installed it globally
At the command line
cd <project-root> && npm install --save-dev gulp
In your gulpfile.js
var gulp = require('gulp');
this is a different dependency than the command line dependency (that you installed globally). More specifically, it is the same NPM package, but the command line program will execute code usually from a different entry point in the NPM package then what require('X') will return.
If we go to the package.json file in the Gulp project on Github, it will tell the whole story:
{
"name": "gulp",
"description": "The streaming build system",

"gulp": "./bin/gulp.js"
},
on the other hand, require('gulp') in your code will return the value of this:
https://github.com/gulpjs/gulp/blob/master/index.js
normally we see this in a package.json file as:
"main": "index.js"
but since this is the default, they just omitted it (which is dumb IMO, better to be explicit, but they aren't the first project I have seen take the lame shorthand route.).
Its occurs on Windows and usually one of the following fixes it:
If you didn't, run npm install gulp on the project folder, even if
you have gulp installed globally.
Normally, It isn't a problem on Windows, but it could be a issue with
the PATH. The package will try to get the PATH from the environment,
but you can override it by adding exec_args to your gulp settings.
For example, on Ubuntu:
"exec_args": {
"path": "/bin:/usr/bin:/usr/local/bin"
}
Hope It will be OK.

Why "gulp-jest" is failing with: "Please run node with the --harmony flag!"?

I get the following error when running gulp test:
Error: Please run node with the --harmony flag!
Here is my gulp task:
var jest = require('gulp-jest');
gulp.task('test', function() {
return gulp.src('src/**/__tests__').pipe(jest({
rootDir: 'src',
scriptPreprocessor: '../node_modules/6to5-jest',
unmockedModulePathPatterns: [ 'react' ]
}));
});
To reproduce: https://github.com/SEEK-Jobs/react-playground
Note that npm test works properly (test is failing as expected), but gulp test fails with the error above. Both npm test and gulp test have the same config object:
{
rootDir: 'src',
scriptPreprocessor: '../node_modules/6to5-jest',
unmockedModulePathPatterns: [ 'react' ]
}
What am I doing wrong?
As far as I can tell the error is thrown from jest-cli.
The reason you don't get it with npm test is that you probably configured npm to run the jest bin script directly, which uses harmonize to programmatically set the --harmony flag.
You can fix by installing harmonize and putting require('harmonize')() in your gulpfile.
It was a bug in gulp-eslint, and it is fixed now in version 0.3.0.
