There’s an official guideline https://developer.wordpress.org/plugins/wordpress-org/detailed-plugin-guidelines/ but no automatic test tool for code quality and security.
The plugin team will check your plugin and also gives you some recommendations if something doesn’t fit their standards.
One of my plugins had to be changed to be approved.
It’s a friendly team, they won’t reject your plugin without detailed instructions how to get it approved.
You can also post a link to your plugin here and I can have a quick look if you like.
