TestCafe Runner - Is it possible to pass a constant from the createRunner file to tests

Question

I need to pass a url to all tests executed in a createRunner. I have used args to do this executing tests from command line. Is there a way to pass a constant from the createRunner to tests executed? See createRunner below I am using. Thanks.

const fs = require('fs');
const createTestCafe = require('testcafe');

let testcafe = null;
let runner = null;

createTestCafe('localhost', 1337, 1338)
    .then(tc => {
        testcafe     = tc;
        runner = testcafe.createRunner();

    return runner
        // list multiple test files
        .src([
            'tests/login.js'
        ])
        .browsers(['chrome'])
        .concurrency(2)
        .reporter('slack')
        .run({
            skipJsErrors: true,
            quarantineMode: true,
            selectorTimeout: 30000,
            assertionTimeout: 10000,
            pageLoadTimeout: 15000,
            speed: 0.9
        });
})
.then(failedCount => {
    stream.end();
    console.log('Tests failed: ' + failedCount);
    testcafe.close();
});

A solution is to programmatically inject command-line args. Before returning the runner, insert these lines:

process.argv.push('--foo=bar');
process.argv.push('--yo');

In the test files use minimist to get your custom cli args.
