Install and run

Install the app with npm (it's work well with yarn but we using npm in here):

Step 1: Install packages Open terminal and run commad: npm install

Step 2: Create .env file from .env.example In the terminal run command: cp .env.example .env

Step 3 Update env variables:

• Update port for application.

  Example: PORT=3000

• Update API URL for explorer service.

  Example: REACT_APP_API_URL=http://localhost:8080

• Update WebSocket URL for real-time expolorer service.

  Example: REACT_APP_WS_URL=ws://localhost:8080/ws

• Update API URL for authentication service.

  Example: REACT_APP_AUTH_API_URL=http://localhost:8081

• Update APP URL for other network. Example:

  REACT_APP_TESTNET_APP_URL=http://localhost:3000
  REACT_APP_PREVIEW_APP_URL=http://localhost:3001
  REACT_APP_PREPROD_APP_URL=http://localhost:3002
  REACT_APP_MAINNET_APP_URL=http://localhost:3003
  

• Update Jira Embedded Key to Add Jira Support Widget to explorer

  Example: REACT_APP_JSD_WIDGET_KEY=xxx

• Update link to the cardano price

  Example: REACT_APP_EXT_ADA_PRICE_URL=https://www.coingecko.com/en/coins/cardano

• Update link to the cardano news

  Example: REACT_APP_CARDANO_NEWS_URL=https://cardanofoundation.org/en/news

• Update application network (mainnet, preprod or preview)

  Example: REACT_APP_NETWORK=mainnet

• Configure supported network names (mainnet, preprod or preview)

  Example: REACT_APP_NETWORK_NAMES="{"mainnet":"Mainnet","preprod":"Preprod", ...}"

• Update link takes the name of Bolnisi wine

  Example: REACT_APP_BOLNISI_NAME_API="https://minio.pro.cf-bolnisi-mainnet.eu-west-1.bnwa.metadata.dev.cf-deployments.org/georgian-wine/public/winerymapping.json"

Step 4 Run on localhost

Runs the app in the development mode. Open terminal and run command: npm start

The application will run by default on port 3000. If you want to run the application on another port, please change the PORT in the .env file.

Open http://localhost:3000 to view it in the browser.

Testing with Jest

This app uses Jest for Unit test.

To run your tests, execute the following command:

• npm run jest-test to test all file *.test.ts.

• npm run jest-test-one [file_relative_path] to test a file with [file_relative_path] being relative path of file. Ex: npm run jest-test-one src\commons\utils\helper.test.ts

E2e test with Cypress

This app we use Cypress for e2e testing.

You can run it with following commands:

Open Launchpad: Run npm run cypress:open to open Cypress launchpad.

On opening Cypress, your testing journey begins with the Launchpad. Its job is to guide you through the decisions and configuration tasks you need to complete before you start writing your first test.

To run e2e test with all specs, try this command: npm run cypress:run

Web automation test with Playwright

Pre-installed on local:

• allure commandline
• npm and node js
• add .env to root folder with APPLICATION_URL property pointing to chosen environment e.g.

APPLICATION_URL=<Explorer env url>
API_URL=<Explorer api url>
BLOCKFROST_API_URL=<BlockFrost api url>
BLOCKFROST_API_TOKEN=<BlockFrost api token>
KOIOS_API_URL=<Koios api url>
KOIOS_API_TOKEN=<Koios api token>
USERNAME=<Explorer user>
PASSWORD=<Explorer user password>

Test run in local:

1. Install all packages locally

npm install

2. Install browsers

npx playwright install

3. Run tests for chosen project e.g.

npm run chrome

or

npm run firefox

---

Test run with allure report

1. Run tests in root folder

ALLURE_RESULTS_DIR=.reports/chrome/allure-results npx playwright test --project='chrome'

• there is also shorter command from package.json scripts to run all tests

npm run chrome

• to run specific feature test indicate full path to feature file

npm run chrome playwright/tests/features/sing-up.feature

• to run specific scenario for a feature add tag @only to the scenario and generate test changes:

npx bddgen
npm run chrome playwright/tests/features/sing-up.feature

• more examples and documentation here

2. Generate report

allure generate .reports/chrome/allure-results -o .reports/chrome/allure-report --clean

3. Open report

allure open .reports/chrome/allure-report

Build into production

Execute npm run build

Builds the app for production to the build folder. 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. Your app is ready to be deployed!
