JUnitXmlReporter in docker container

[marekmosna]

Hello there,

I'm running protractor e2e tests in docker image.

FROM mrsheepuk/protractor

RUN npm install --save-dev jasmine-reporters@^2.0.0
RUN npm install --save jasmine-spec-reporter 

when I use TerminalReporter I get nice colorful output. Unfortunately, with JUnitXmlReporter the output is:

Warning: writing junit report failed for '..', 'junitresults-foo.xml'. Reasons:
  PhantomJs attempt: window is not defined
  NodeJS attempt: Unexpected token {

My config:

var reporters = require('jasmine-reporters');
var junitReporter = new reporters.JUnitXmlReporter({
  savePath: '..',
  consolidateAll: false
});

var terminalReporter = new reporters.TerminalReporter({
  verbosity: 3,
  color: true,
  showStack: true
});

var myReporter = {
  specDone: function(result){
    fs = require('fs');
    fs.writeFile('result.txt', 'Suite: ' + result.description + ' was ' + result.status);
    for(var i = 0; i < result.failedExpectations.length; i++) {
      fs.writeFile('target/result.txt', 'AfterAll ' + result.failedExpectations[i].message);
      fs.writeFile('target/result.txt', result.failedExpectations[i].stack);
    }
  }
};

exports.config = {
    seleniumAddress: 'http://localhost:4444/wd/hub',
    framework: "jasmine2",
    specs: ['*.spec.js'],
    // Chrome is not allowed to create a SUID sandbox when running inside Docker  
    capabilities: {
      'browserName': 'chrome',
      'chromeOptions': {
        'args': ['no-sandbox']
      }
    },

      // Options to be passed to Jasmine.
  jasmineNodeOpts: {
    showColors:true,
    defaultTimeoutInterval: 400000,
    isVerbose: true,
    includeStackTrace: true
  },

   onPrepare: function() {
        jasmine.getEnv().addReporter(junitReporter);
    }

  };

Can you please help me to fix it?
Many thanks
