nl_tokens: not really disposable no way to get an instance with a different database too expensive to open new connection for each test but this will still work as intended for single thread tests .
pl_tokens: async function disposable ( ) { const name = "tmp" + Math . floor ( Math . random ( ) * 10000 ) ; await connection . dbCreate ( name ) . run ( ) ; const r = Object . <mask> ( connection ) ; r . dispose = async function ( ) { await this . dbDrop ( name ) . run ( ) ; } ; r . _poolMaster . _options . db = name ; return r ; }
