Design reliable tests for modern React and Vue applications

Training program

Module 1Vitest Fundamentals: Installation and First Unit Tests (Vite, Jest-like API, Configuration)

Discover Vitest by installing the environment with Vite, create your first test project, master the syntax for basic tests like expect and matchers, perform practical exercises on simple JavaScript functions, generate initial reports and integrate snapshots to validate expected outputs, all while benefiting from immediate feedback from the trainer for rapid and confident progression.

Module 2Advanced Vitest Tests: Mocks, Spies, and State Management (Vi.mock, jest.fn, Hooks Testing)

Dive into mocks to isolate external dependencies, configure spies to monitor function calls, test React components with hooks like useState and useEffect, apply these techniques to real business cases such as user authentication, produce maintainable test suites with automatic cleanup, and optimize execution speed for smooth and productive development cycles.

Module 3Vitest Coverage and Integration: Reports, Parallelism, and Integration Tests (Coverage, --threads, DOM Testing)

Measure code coverage with Vitest's built-in tools, enable parallel mode to speed up large executions, integrate DOM tests via jsdom to simulate a browser, analyze real projects with minimum coverage thresholds, generate detailed HTML reports and GitHub badges, apply all this to your red thread project by identifying critical weaknesses for immediate professional software quality.

Module 4Vitest Deployment: CI/CD, Best Practices, and Certifying Project (GitHub Actions, Advanced Vitest Config, Refactoring)

Integrate Vitest into CI/CD pipelines like GitHub Actions or GitLab, adopt best practices for resilient and scalable tests, refactor your red thread project with lightweight end-to-end tests, customize Vitest configuration for enterprise environments, produce a complete deliverable with documentation and automated deployment, and validate your skills through a practical assessment for recognized certification in professional training.
