Sample testing boilerplate

package main

type Entity struct {
 Key        string
 CreatedAt  time.Time
 Labels     []string
 Data       any
}


func main () {

 // Add A with labels [1]

 // Add B with labels [1,2]

 // Add C with labels [3]
  
 // List - returns all 3
  
 // List with labels [1] - returns A, B
  
 // List with labels [2] returns B
  
 // List with labels [2,3] returns B, C
  
 // Delete A
  
 // List - returns B, C
