Starting with Eclipse + Validation Issues with Javascript

I have installed Eclipse for PHP Developers (Oxygen package). I am not getting error messages for javascript. (for example, it is not showing error or warning even if semi-column for some lines are missing or statements like x=x is present)
I have referred this question . Accordingly, enabled all the validations.
Still Eclipse does not show warnings or error for javascript. I did clean build also but it did not help. For php, it is working fine.
Could anyone help me to know what I am doing wrong with the configuration.
EDIT: Errors are missing for files with js extension. Attaching sample file content below (content of a file test.js)
var test = 'hello';
test = test;
var test2 = 'e'
alert('hello');

Mocha complains Reference Error: URL is not defined

Sorry I don't know if this is a stupid question or not but I cannot find the answer.
I have a pure function in javascript which check if the argument is a correct URL
isValidUrl(url) {
const protocol = new URL(url).protocol;
...
}
The code runs fine in browser. But I would like to write a test using mocha for it. And mocha complains "ReferenceError: URL is not defined". So does that mean server side JS does not have URL class? Do I need to use something like headless browser to test it?
Thanks a lot.

Node and friends, where your tests are likely running, implement the ECMAScript (JS) spec. The URL class is from this WhatWG spec. The JS spec does not have any reference to a URL class, which explains your immediate problem.
Node also implements its own CommonJS-based modules, one of which is a URL module. It doesn't appear to have the same interface, however.
Using Mocha with Karma to run tests in a headless browser, like PhantomJS, is probably a better solution. You'll get an accurate, if slightly out of date, version of chromium to test within. You can also set Karma up to use other browsers, if they are available on the test machine.

SonarQube, sonar-javascript and JSTestDriver - ressource not found

I need your help/guidance about one problem I have for the last two days.
The sonar-javascript plugin is not able to get the results of my Javascript UnitTests. I am generating unit tests and lcov results using JSTestDriver. The lcov results are working and are correctly shown in SonarQube. I also have to say that I am using Windows. Here is the error I have:
Test result will not be saved for test class "UnitTests.controlesTest", because SonarQube associated resource has not been found using file name: UnitTests\controlesTest.js"
The error is very similar to this one: Importing javascript XML JUnit tests to sonar using jstestdriver fails. However, this error seems to be fixed in the last SNAPSHOT (2.8). The file I am trying to access is stored in UnitTests/controlesTest.js. I tried to go into the sonar-javascript source, and find a way to correct this issue (at least, try to understand it). I ended up in the file JsTestDriverSensor.java in the function getTestFileRelativePathToBaseDir. I found that this line is not able to get my file (UnitTests\controles.js). Actually, fileIterator does not contain any InputFile.
Iterator<InputFile> fileIterator = fileSystem.inputFiles(predicate).iterator();
So I tried different predicates to understand why my file is not found. At the end, I found that the following predicate fileSystem.predicates().hasType(InputFile.Type.TEST) is the reason why this file is not found. A quick fix is to change:
- 108 testFilePredicate,
+ 108 mainFilePredicate,
I must be doing something wrong, maybe someone has an idea ?

The "sonar.tests" property has to be set in the sonar-project.properties (or in newer version SonarQube.Analysis.xml). This allows the sonar-javascript plugin to find the javascript test files.

Phpstorm with protactor unresolved functions

I`m using phpstorm with protactor for angular and for some reason the IDE doesnt recognize some
functions. but the functions is working fine when i`m running the test.
for example:
element(by.buttonText('toggle')).click();
expect(element(by.css('.net-fade')).getText()).
toEqual('something');
})
The IDE tell me that the method by.css is "unresolved function or method".
Someone know how to fix it?

I'm not familiar with PHPStorm, so this won't be a full-answer:
But I'd say the basic problem is that Protractor binary auto-inserts protractor.js and other dependencies into the environment for you. This is what gives you by (along with other helper variables browser, element, etc).
You may want to insert protractor.js yourself, you can find it in
node_modules/protractor/lib/protractor.js
(And again, I am unsure of how PHPStorm includes files, but you might want to only manually add protractor.js if it is not running in test mode. And to this end, you could set flag in protractors onPrepare() function to check against).

Can I use jQuery.post() with LiveServerTestCase?

I'm writing a test using a LiveServerTestCase, django-casper, and casperjs for a view that includes javascript. Half way through a client side script I have a jQuery.post(url, callback_function(r){}) line.
When callback_function is called during a test r is null. However, when I run the application normally and step through the same javascript when callback_function is called r has the expected value.
This makes me think that there is a detail about LiveServerTestCase I'm missing to get jQuery.post to work with it. Can anybody please shed light on what I should do next to debug this problem?

I'm guessing it's because the static files aren't around. In Django 1.7, LiveServerTestCase no longer supported serving up the static files. It was moved into testing.StaticLiveServerTestCase
Try changing your test classes to subclass StaticLiveServerTestCase.
