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 onlyjest
)
- this will install the dependencies listed in
-
The description for each kata is described in the respective files in
src/
. The corresponding tests are intest/filename.test.js
. -
To run the tests, run
npm test
in your terminal.-
Inside
package.json
, we have definednpm test
to execute thejest
command, which will run all the tests in the project. -
We have also defined 2 additional commands:
-
npm run test:watch
, which is executing thejest --watch
command. The--watch
option will rerun the tests everytime you save a file. -
npm run test:coverage
, which is executing thejest --coverage
command. The--coverage
option produces a test coverage report after running the tests
-
-
-
To quit the test runner, hit
q
in the terminal wherejest
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(...)
totest(...)
. -
Have fun! And enjoy the dopamines that come with seeing green!
