    const ws = fs.createWriteStream('./test/result');
    const checker = Checker(rs, ws)
    const ruleCreator = RuleCreator()
    const rules = ruleCreator.defaultRules();
    const newRule = ruleCreator.createRuleObject(
        ruleCreator.createNumberChecker(
            "head>meta[name=robots]", 1, "min"
        ),
        `Header doesn't have <meta name="robots"> tag`
