How to use the debug.formatArgs function in debug

const debug = require('debug')
const util = require('util')

debug.recorded = []

// enable all logs while running the tests
debug.enable('thumbsup:*')

// don't format the logs to avoid any extra ANSI codes
debug.formatArgs = function (args) {
}

// capture the logs instead of displaying them
debug.log = function () {
  const message = util.format.apply(null, arguments)
  debug.recorded.push(`${this.namespace} ${message}`)
}

debug.reset = function () {
  debug.recorded = []
}

debug.assertContains = function (expected) {
  const matches = debug.recorded.filter(message => {
    return message.includes(expected)
  })

}
  } else {
    try {
      alog = require('./build/Release/silk-alog.node');
    } catch (err) {
      // Fall back to using console.*
    }
  }

  // If DEBUG environment variable is not set, select a sensible default.
  if (!process.env.DEBUG) {
    debug.enable('silk-*,-silk-*:debug,-silk-*:verbose');
  }
}

debug.formatArgs = function(args) {
  const diff = debug.humanize(this.diff);

  // Mimic console.* functions by treating additional arguments as
  // printf-style arguments.
  let msg = util.format.apply(util, args);
  args.length = 1;

  const format = `(+${diff}) ${msg}`;
  if (this.useColors) {
    msg = `\u001b[3${this.color}m${format}\u001b[0m`;
  } else {
    msg = format;
  }

  args[0] = msg;
};
