# 설치 가이드

1. 코드 내려받기

git clone https://github.com/zaqqaz/visual-unit-tests

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd visual-unit-tests

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Node.js

쉬움 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Node.js npm 명령어를 쓰려면 Node.js가 설치되어 있어야 합니다. LTS(장기지원) 버전을 추천합니다.

npm install

package.json에 명시된 라이브러리들을 내려받아 설치합니다.

npm start

개발/실행 서버를 켭니다.

✅ 명령어 실행 후 터미널에 나타나는 주소(보통 http://localhost:3000 형태)를 브라우저에서 열어보세요.

Demo project with Typescript/React/React Testing Library/Jest.

FYI: Latest version of the project makes demo with styled-components, but you can see history (and attached videos) to discover options with css/pcss.

**Features:**
 - Nice reports with [jest-allure](https://github.com/zaqqaz/jest-allure)
 - Screenshots tests with [puppeteer](https://github.com/GoogleChrome/puppeteer) & [jest-allure-image-snapshot](https://github.com/zaqqaz/jest-allure-image-snapshot)
 - CircleCi integration
 
### [Talk](https://denis.by/visual-tests/)

</a>

>During this talk we’ll discuss why we bet on visual unit tests. On a real example we’ll discover how to implement such tests for **React** application with **Jest** and **Puppeteer**, we’ll meet **Allure report** with Jest and in the end set up the full pipeline with **CircleCi** and GitHub to run our own visual tests on each pull request. Also we’ll consider performance and some tricky parts.

**Report example:**

<img width="450" alt="Visual unit tests allure report" src="https://user-images.githubusercontent.com/2823336/52945569-b0fe6700-337a-11e9-95e1-6ac624ef018b.png">

### Available Scripts

In the project directory, you can run:

#### `yarn start`

Runs the app in the development mode.<br>
Open [http://localhost:3000](http://localhost:3000) to view it in the browser.

The page will reload if you make edits.<br>
You will also see any lint errors in the console.

#### `yarn test`

Launches the test runner in the interactive watch mode.<br>
See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.

#### `yarn run build`

Builds the app for production to the `build` folder.<br>
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.<br>
Your app is ready to be deployed!

See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
