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.

Instructions

• 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 yarn test in your terminal.

  • Inside package.json, we have defined yarn test to execute the jest command, which will run all the tests in the project.

  • We have also defined 2 additional commands:

    • yarn test:watch, which is executing the jest --watch command. The --watch option will rerun the tests everytime you save a file.

    • yarn 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
  • leapYear.js
  • sumWithoutHighestAndLowest.js
  • firstNonConsecutiveNumber.js
  • findMultiples.js

• Once you've passed the first test, change the next test from xit(...) to it(...).

• Have fun! And enjoy the dopamines that come with seeing green!
