Infinite loop

[FunnyGhost]

Hello,

I am working on a project with angular cli. Up until a few days ago I was using karma out of the box and chrome and everything works. However, I want a headless browser for my CI and I am trying to use karma-phantomjs-launcher.
The problem is that it never stops executing tests. Even with single run it executes them over and over again.
Here is the debug level info:

....
PhantomJS 2.1.1 (Windows 8 0.0.0): Executed 24 of 27 SUCCESS (0 secs / 8.736 secs)

PhantomJS 2.1.1 (Windows 8 0.0.0): Executed 112 of 27 SUCCESS (0 secs / 39.392 secs)

And it just goes on and on like this.
The last test that I added is this:

    it('should break', () => {
        expect(true).toBe(false);
    });

So, it should fail, but apparently is not even executed.
Here is my karma.conf.js file:

// Karma configuration file, see link for more information
// https://karma-runner.github.io/0.13/config/configuration-file.html

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular/cli'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-phantomjs-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular/cli/plugins/karma')
    ],
    client: {
      clearContext: false // leave Jasmine Spec Runner output visible in browser
    },
    files: [
      { pattern: './src/test.ts', watched: false }
    ],
    preprocessors: {
      './src/test.ts': ['@angular/cli']
    },
    mime: {
      'text/x-typescript': ['ts', 'tsx']
    },
    coverageIstanbulReporter: {
      reports: ['html', 'lcovonly'],
      fixWebpackSourcePaths: true
    },
    angularCli: {
      environment: 'dev'
    },
    reporters: config.angularCli && config.angularCli.codeCoverage
      ? ['progress', 'coverage-istanbul']
      : ['progress', 'kjhtml'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['PhantomJS'],
    customLaunchers: {
      'PhantomJS_custom': {
        base: 'PhantomJS', 
        flags: ['--load-images=false'],
        debug: false
      }
    },
    phantomjsLauncher: {
      // Have phantomjs exit if a ResourceError is encountered (useful if karma exits without killing phantom) 
      exitOnResourceError: true
    },
    singleRun: false
  });
};

The command I am running is:
ng test -sr --log-level=debug --browsers PhantomJS_custom

try :
ng test --single-run

I have this issue also

I ran into this because I had junitReporter putting an output file in src/app, which caused it to be watched, so it would trigger a relaunch, update the output file, relaunch, update the output, etc.

So if your tests generate output files, don't put them where they'll be watched.

In karma.config.js file set singleRun to true. Mine was set to false.
I tried command line for singleRun and it didnt work.
singleRun: true ==========> I had this set to false, setting this to true helped

// https://karma-runner.github.io/0.13/config/configuration-file.html

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' ],
      fixWebpackSourcePaths: true
    },
    reporters: [ 'progress', 'kjhtml' ],
    port: 9876,
    browsers: [ 'Chrome' ],
    logLevel: config.LOG_INFO,
    singleRun: true ==========> I had this set to false, setting this to true helped
  } );
};

All is well.
