Welcome to the "test-with-jest" project! This is a simple project that demonstrates the basics of unit testing with Jest. If you're new to unit testing or just getting started with Jest, this project serves as an excellent introduction.
To run the tests for this project, you'll need to have Node.js and npm (Node Package Manager) installed. If you haven't already installed them, you can download and install them from nodejs.org.
Once you have Node.js and npm set up, follow these steps:
-
Clone this repository to your local machine:
git clone https://github.com/your-username/test-with-jest.git
-
Change to the project directory:
cd test-with-jest -
Install the project dependencies using npm:
npm install
-
Run the tests with the following command:
npm test
The project structure is quite simple. Here's a quick overview:
-
add-five.js: This file contains a simple function,addFive, which takes a number and returns that number plus 5. -
index.test.js: This is the test file for theaddFivefunction. It includes a single test case that ensures the function behaves as expected. -
package.json: The project's package file lists the dependencies and scripts. In this case, it includes Jest as a development dependency and a "test" script that runs Jest.
Here's an example of the test in index.test.js:
const addFive = require('./add-five');
test('returns the number plus 5', () => {
expect(addFive(1)).toBe(6);
});This test checks if the addFive function correctly adds 5 to the input value and returns the expected result.
This project is based on the course "Advanced React," which covers various advanced React concepts and features. While this project is relatively simple, it serves as a starting point for understanding unit testing with Jest and can be a helpful companion to the course.
