Training program

Module 1Day 1: Vitest Installation and Configuration (Vite, setup, base tools)

Dive into Vitest by installing the tool in your Vite project, configure vite.config.js and vitest.config.ts for lightning-fast launches, explore advanced matchers through practical exercises on simple JS modules, create your first test suite with coverage enabled, leave with a configured project ready to scale.

Module 2Day 2: Advanced Unit Tests (assertions, hooks, patterns)

Master in-depth expect assertions and test/beforeEach hooks on concrete cases like utility functions, implement parameterized tests to cover multiple scenarios, integrate TypeScript for type-safe tests, generate detailed reports, experience the acceleration thanks to Vitest's native parallelization.

Module 3Day 3: Vitest Mocking and Spies (dependencies, simulated APIs)

Simulate external modules and APIs with vi.mock and vi.spy, test async/await functions without real calls, apply to real e-commerce examples, debug complex interactions, generate automated mocks to speed up development, leave as an expert in test isolation for maximum reliability.

Module 4Day 4: Component Tests (React/Vue, virtual DOM, user events)

Test React components with @testing-library and Vitest, simulate clicks and inputs via userEvent, integrate Vue Testing Library for hybrid apps, analyze intelligent snapshots, optimize for mobile/desktop, build a portfolio of simplified end-to-end tests, feel the power through collaborative live coding.

Module 5Day 5: Optimization, CI/CD, and Vitest Best Practices (performance, deployment)

Accelerate your suites with watch mode and pool workers, integrate Vitest with GitHub Actions for smooth CI/CD, apply TDD refactoring on a capstone project, measure coverage >90%, secure with secrets management, conclude with a personal audit of your tested code, ready to boost your production deployments.
