Exercise: Databases

Challenge

In this exercise, your challenge is to create a helper function to test a function that requires data from a database.

Problem statement

You can use helper functions to instantiate and populate a temporary database to assist with testing parts of your code that require data from a database.

Coding challenge

Create a helper function to set up a temporary database to assist with testing the function pomodoro.RangeSummary. We’ll provide the test function.
