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!
