+     * Checks that Json matches provided types.
+     * In case you don't know the actual values of JSON data returned you can match them by type.
+     * Starts check with a root element. If JSON data is array it will check the first element of an array.
+     * You can specify the path in the json which should be checked with JsonPath
+     *
+     * Basic example:
+     *
+     * ```php
+     * <?php
+     * // {'user_id': 1, 'name': 'davert', 'is_active': false}
+     * $I->seeResponseMatchesJsonType([
+     *      'user_id' => 'integer',
+     *      'name' => 'string|null',
+     *      'is_active' => 'boolean'
+     * ]);
+     *
+     * // narrow down matching with JsonPath:
+     * // {"users": [{ "name": "davert"}, {"id": 1}]}
+     * $I->seeResponseMatchesJsonType(['name' => 'string'], '$.users[0]');
+     * ?>
+     * ```
+     *
+     * In this case you can match that record contains fields with data types you expected.
+     * The list of possible data types:
+     *
+     * * string
+     * * integer
+     * * float
+     * * array (json object is array as well)
+     * * boolean
+     *
+     * You can also use nested data type structures:
+     *
+     * ```php
+     * <?php
+     * // {'user_id': 1, 'name': 'davert', 'company': {'name': 'Codegyre'}}
+     * $I->seeResponseMatchesJsonType([
+     *      'user_id' => 'integer|string', // multiple types
+     *      'company' => ['name' => 'string']
+     * ]);
+     * ?>
+     * ```
+     *
+     * You can also apply filters to check values. Filter can be applied with `:` char after the type declaration.
+     *
+     * Here is the list of possible filters:
+     *
+     * * `integer:>{val}` - checks that integer is greater than {val} (works with float and string types too).
+     * * `integer:<{val}` - checks that integer is lower than {val} (works with float and string types too).
+     * * `string:url` - checks that value is valid url.
+     * * `string:date` - checks that value is date in JavaScript format: https://weblog.west-wind.com/posts/2014/Jan/06/JavaScript-JSON-Date-Parsing-and-real-Dates
+     * * `string:email` - checks that value is a valid email according to http://emailregex.com/
+     * * `string:regex({val})` - checks that string matches a regex provided with {val}
+     *
+     * This is how filters can be used:
+     *
+     * ```php
+     * <?php
+     * // {'user_id': 1, 'email' => 'davert@codeception.com'}
+     * $I->seeResponseMatchesJsonType([
+     *      'user_id' => 'string:>0:<1000', // multiple filters can be used
