How to do in karma so that the browser does not close after the tests?

Question

Google Chrome

Good afternoon, help me make sure that the browser does not close after the tests, because I want to see what's in the console. All googdzh comes down to changing three settings and each one is different, but it didn’t help me!
My karma settings file

module.exports = function (config) {
    config.set({

        // base path that will be used to resolve all patterns (eg. files, exclude)
        basePath: '',


        // frameworks to use
        // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
        frameworks: ['jasmine'],


        // list of files / patterns to load in the browser
        files: [
            'dist/run.full.js',
            'dist/tests/unit-tests/config2/**/*.spec.js'
        ],

        proxies: {
            '/unit-tests/': '/base/dist/tests/unit-tests/'
        },


        // list of files to exclude
        exclude: [
        ],


        // preprocess matching files before serving them to the browser
        // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
        preprocessors: {
            // '**/*.ts': ['typescript']
        },


        // test results reporter to use
        // possible values: 'dots', 'progress'
        // available reporters: https://npmjs.org/browse/keyword/karma-reporter
        reporters: ['progress'],


        // web server port
        port: 9876,


        // enable / disable colors in the output (reporters and logs)
        colors: true,


        // level of logging
        // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
        logLevel: config.LOG_INFO,


        // enable / disable watching file and executing tests whenever any file changes
        autoWatch: false,


        // start these browsers
        // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
        browsers: ['Chrome'],
        // browsers: ['ChromeHeadless'],


        // Continuous Integration mode
        // if true, Karma captures browsers, runs the tests and exits
        singleRun: false,

        // Concurrency level
        // how many browser should be started simultaneous
        concurrency: Infinity
    });
};

I didn’t find something in the docks how to solve it, now I have to set a timeout for this, well damn it’s a game just to do it!
