Wierd issue when running with jest #489
Description
I know this is very little information, but I've encountered the following when executing some tests with Jest, which touches code that connects to MySQL using node-mysql2, but the code makes no queries.
Any ideas on what causes this issue? The code is fine, when executed directly.
