Most developers today are required not only to write code, but they also need to write code to test their own code 😱, yes.. really.
Today we are going to be using the jest framework to create our first tests.
This project comes with the necessary files to start working, but you have two options to start:
a) Use gitpod: open this link in your browser to clone it with gitpod: https://gitpod.io#https://github.com/breatheco-de/exercise-unit-test-with-jest.git
b) You can clone this repository on your local computer:
$ git clone https://github.com/breatheco-de/exercise-unit-test-with-jest.git💡 Important: Remember to create a new repository, update the remote (git remote set-url origin <your new url>), and upload the code to your new repository using add, commit and push.
Then follow this instructions:
- Get into the exercise folder:
$ cd exercise-unit-test-with-jest - Download learnpack globally (if you don't have it already):
$ npm i learnpack -g - Start the exercise:
$ learnpack start
We are going to be using the Jest library to build a program capable of converting numeric values from one currency to another:
| Function name | Description |
|---|---|
| fromDollarToYen | Receives a dollar amount and returns equivalent amount in Japan Yen |
| fromEuroToDollar | Receives a Euro amount and returns equivalent amount in US Dollar |
| fromYenToPound | Receives a Yen amount and equivalent amount in England Pound |
