Why are we doing this?

These challenges are designed to develop your problem-solving skills.

In this exercise you need to build an alarm clock which meets the following criteria:

Acceptance criteria

• Given the user has entered a number in the input field
  When the user clicks the "Set Alarm" button
  Then the "Time Remaining" title should update to show the entered number in mm:ss format

• Given the alarm is set with a valid time
  When one second passes
  Then the "Time Remaining" title should decrement by 1 second

• Given the alarm is set with a time of 00:00
  When the timer reaches 00:00
  Then the alarm sound should play continuously

• Given the alarm sound is currently playing
  When the user clicks the "Stop Alarm" button
  Then the alarm sound should stop playing

• Given the alarm is set with a time of 00:10
  When the timer reaches 00:00
  Then the background colour should change
  And the alarm sound should play

• Given the user has not set an alarm
