How to add script attribute to tag in karma config?

Question

JavaScript

Or how can this be done at all?
It is necessary for the script that is being tested to set an attribute (the value of which may be different), the script reads it.

module.exports = function (config) {
    config.set({
        basePath: '',
        frameworks: ['jasmine'],
        files: [
            'dist/main.js',
            'dist/tests/main.spec.js'
        ],

        reporters: ['progress'],
        port: 9876,
        colors: true,
        logLevel: config.LOG_INFO,
        autoWatch: false,
        browsers: ['ChromeHeadless'],
        singleRun: true,
        concurrency: Infinity
    });
};

In this case, the main.js script should be added to the page with the attribute

<script src="[main.js]" data-components="component1, component2"></script>
