Assignment-3

Pre Steps:

• Clone this repository into your local machine
• Run 'npm install'
• Run 'npm test -- --coverage'
• Open /coverage/lcov-report/index.html
• Click on calculator.js
• At the top observe the % of Lines covered
• In the main branch create a github workflow for automated testing (For example: https://lannonbr.com/blog/2020-03-30-github-actions-ci-tests)
• Create another branch from main
• Open /coverage/lcov-report/index.html and observe the % of lines covered
• Write more unit tests to bring the Line coverage % above 80%
• Push the changes to the branch on Github
• Then create a pull request to the main branch
• Observe the 'Actions' tab of the respository
• The workflow that you created earlier should start running and it should pass (Its called Continuous Integration)
• If its not passing, fix the code / unit tests and push the code again to your branch (the pull request is already created so no need to create a new one)
• If its passing then merge the Pull Request with main (Its called Continuous Deployment)
• Create a docker hub free account for the purpose of this assignment and create your first free repository (remember this name)

Assignment Deliverables:

• On your local machine, create a Dockerfile for the project with appropriate configuration
• Build the docker file and let it succeed
• Once its built, tag the docker file with the tag name "release"
• Push the docker image to your docker hub repository that you created earlier after creating docker hub account.
• Additionally, write a github actions script for deploying building, tagging and deploying the docker image to your docker hub account
• Run the newly created github action if its not already running and wait for it to succeed.
• Then check your docker hub repository, you should see a build image there with a tag name "release".
• Create a new text file in this repo, include your docker hub repository url in it. This will be your final submission.
