TDD with Jest

Let's get good at TDD! Work through the katas in this repo and practice your TDD chops.

For this assignemnt, we will be using Jest, which is a popular javascript testing framework created and used by Facebook.

Fork and clone the repo
cd into the repo
Run npm install
- this will install the dependencies listed in package.json (for this assignment, it's only jest)
The description for each kata is described in the respective files in src/. The corresponding tests are in test/filename.test.js.
To run the tests, run npm test in your terminal.
- Inside package.json, we have defined npm test to execute the jest command, which will run all the tests in the project.
- We have also defined 2 additional commands:
  - npm run test:watch, which is executing the jest --watch command. The --watch option will rerun the tests everytime you save a file.
  - npm run test:coverage, which is executing the jest --coverage command. The --coverage option produces a test coverage report after running the tests
To quit the test runner, hit q in the terminal where jest is running.
Do the assignments in this order:
- fizzbuzz.js
- sumWithoutHighestAndLowest.js
- firstNonConsecutiveNumber.js
- findMultiples.js
Once you've passed the first test, change the next test from test.skip(...) to test(...).
Have fun! And enjoy the dopamines that come with seeing green!

Part 2: Testing state

Add tests for the methods in account.js
Update the deposit() method so that it does nothing when the account balance before depositing is 5000 or more
Update the withdraw() method so that it does nothing when the account balance before withdrawing is 0 or less
