In this assignment let's build a Stopwatch by applying the concepts we have learned till now.

Refer to image below:

Design Files

• Extra Small (Size < 576px), Small (Size >= 576px)
• Medium (Size >= 768px), Large (Size >= 992px) and Extra Large (Size >= 1200px)

Project Set Up Instructions

• Download dependencies by running npm install
• Start up the app using npm start

Project Completion Instructions

Add Functionality

The app must have the following functionalities

• When the Start button is clicked the Stopwatch should start running.

• When the Stop button is clicked the Stopwatch should stop running.

• When the Reset button is clicked the Stopwatch should be reset to zero.

• Your task is to complete the implementation of

  • src/components/Stopwatch/index.js.
  • src/components/Stopwatch/index.css.

Important Note

The following HTML attributes are required for the HTML button and image elements for the tests to pass

• The HTML main heading element to display the time should have the testid attribute and its value as timer

Quick Tips

Things to Keep in Mind

• All components you implement should go in the src/components directory.
• Don't change the component folder names as those are the files being imported into the tests.
• Do not remove the pre-filled code
