How to install project

Download this repository and open it main folder, then:

1. Install packages:

   npm i
   

2. Install Playwright browsers:

   npx playwright install
   

3. Configure playwright.config.json

   • Set baseURL to your app main url.
   • Set timeout to desired value (current 6s can be to short)

How to run tests

There are few ways of test running:

1. Navigate to folder with given exercise an simply run test by pressing green arrow
2. Open Testing tab located in left menu (flask icon), unfold all tests and choose one or as many as you want to be run. If test not appears, refresh tab or check playwright.config.ts if you have everything set properly with projects section.
3. Run npm scripts by copy pasting scripts form package.json form scripts section.
4. Use VSC npm script run section:
   • in Explorer tab menu check NPM Scripts
   • in very bottom of Explorer tab you will find section NPM SCRIPTS
   • choose script you want to run

UI Mode

Just run script form package.json:

npm run test:ui

Recommended option is running this script in separate console.

Tips

• there are two main folder for tests and you can compare implementation with or without mocking
• broke test and try to find problem in report
• some tests are designed to fail and those tests contains tag @fail in name
• if tests fail without clear reason:
  • check if tested app is up and running,
  • check timeout in playwright.config.ts (on slow machines it need to be increased)
