FAQPage Schema

How do I migrate Angular tests from Karma and Jasmine to Vitest?▼

To migrate Angular tests from Karma and Jasmine to Vitest, the Skill performs preflight checks, updates the test builder target in angular.json, swaps dependencies using npm, and refactors spec files to remove outdated Jasmine-specific APIs.

Why should I switch my Angular testing framework to Vitest?▼

Switching your Angular testing framework to Vitest significantly improves test execution speed and developer experience, providing a faster development feedback loop for Angular 20 projects compared to the outdated Karma test runner.

Does the Angular Vitest migration work with Angular 20 projects?▼

Yes, the Vitest migration is explicitly applicable for Angular 20 projects. It requires npm for dependency management and Angular CLI for workspace configuration to ensure a smooth transition.

What is the best way to update Jasmine-specific APIs in Angular spec files?▼

The best way to update Jasmine-specific APIs in Angular spec files is through automated refactoring during the Vitest migration, which replaces outdated Jasmine syntax to ensure compatibility with the new test runner.

How do preflight checks work when migrating Angular workspaces to Vitest?▼

Preflight checks verify workspace readiness before making any changes to ensure a deterministic migration. They validate the environment before updating angular.json and managing the Vitest and Karma dependencies.

What are the limitations of migrating Angular tests to Vitest?▼

Limitations include requiring npm for dependency management and Angular CLI for workspace configuration. The migration targets Angular 20 projects and may require manual intervention if spec files contain complex Jasmine-specific APIs that cannot be automatically refactored.
