Training program

Module 1Introduction to Vitest: installation and first tests (Vite tools, assertions, basic exercises)

Dive into Vitest from the morning by installing the tool on a real Vite project, configure vite.config.js for seamless integration, write your first unit tests on simple functions with expect and matchers, follow up with practical exercises on React components, generate an initial coverage report, experience the stunning speed of tests running in milliseconds, and leave with a ready-to-use setup.

Module 2Advanced Vitest Tests: mocks, spies, and hooks (vi.mock methods, beforeEach, real-world async cases)

Move to complex tests by mocking external modules with vi.mock to isolate dependencies, implement spies to verify function calls, test promises and custom hooks through exercises on simulated API fetch, debug common failures with Vitest UI, build a test suite on a real e-commerce project, measure 90% code coverage, experience the thrill of green tests that boost your development confidence.

Module 3Vitest Optimization and Integration: CI/CD, coverage, and best practices (GitHub Actions, reports, final deliverables)

Finalize by optimizing speed with parallelization and snapshot testing on large projects, integrate Vitest into GitHub Actions for automated CI tests, generate detailed HTML reports with coverage thresholds, apply best practices via a complete capstone project, export production-ready deliverables, master advanced debugging, and leave as an expert ready to scale tests in any agile team.
