Docsify Testing

Environment

• Jest: A test framework used for assertions, mocks, spies, etc.
• Playwright: A test automation tool for launching browsers and manipulating the DOM.
• Jest-Playwright: A Jest preset that simplifies using Jest and Playwright together

Test files

• E2E tests are located in /test/e2e/ and use Jest + Playwright.
• Integration tests are located in /test/integration/ and use Jest.
• Unit tests located in /test/unit/ and use Jest.

Global Variables

• process.env.TEST_HOST: Test server ip:port
