Cannot load browser "ChromiumNoSandbox": it is not registered! Perhaps you are missing some plugin?

[NicolaSpreafico]

Hello, we are creating a pipeline for a node project.

Our goal is obtain the lcov.info file (which will later read by SonarQube) with the command

ng test --code-coverage

From our local machine is working fine, so I consider the project itself correctly configured.

This is our karma configuration (as written in the documentation we added the browser definition)

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular-devkit/build-angular'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular-devkit/build-angular/plugins/karma')
    ],
    client: {
      clearContext: false // leave Jasmine Spec Runner output visible in browser
    },
    coverageIstanbulReporter: {
      dir: require('path').join(__dirname, '../coverage'),
      reports: ['html', 'lcovonly', 'text-summary'],
      fixWebpackSourcePaths: true
    },
    reporters: ['progress', 'kjhtml'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ["ChromiumNoSandbox"],
    //browsers: ["ChromeHeadless"],
    customLauchers: {
      ChromiumNoSandbox: {
        base: 'ChromiumHeadless',
        flags: ['--no-sandbox', '--headless', '--disable-gpu', '--disable-translate', '--disable-extensions']
      }
    },
    singleRun: false
  });
};

This is our docker image:

FROM rastasheep/alpine-node-chromium:10-alpine
ARG ng_version=latest
RUN npm install -g @angular/cli@$ng_version --unsafe-perms && \
    ng version
ENTRYPOINT ["ng"]

We started from this image and we added the ng command line which will be used from our project.

When the pipeline is running and the image is loaded, we are getting this error:

This is the error:

Cannot load browser "ChromiumNoSandbox": it is not registered! Perhaps you are missing some plugin?

We completed the Karma configuration with the example we found on this repository README, and it should work. Do you have any suggestion on what is missing from our configuration?

@NicolaSpreafico Have you checked this issue https://github.com/karma-runner/karma-chrome-launcher/issues/165 ?

[NicolaSpreafico]

@rastasheep Unfortunately the issue you linked was solved by updating karma-chrome-launcher to the version 2.2.0 We are already using that version but we're still having this issue.

      "karma": "~4.1.0",
        "karma-chrome-launcher": "~2.2.0",
        "karma-coverage-istanbul-reporter": "~2.0.1",
        "karma-jasmine": "~2.0.1",
        "karma-jasmine-html-reporter": "^1.4.0",

[rastasheep]

Hmm its really hard to debug it without working example, can you try to create minimal setup than can reproduce issue?
