| content.faq | `[{"answer":"BrowserStack offers a grid of 3000+ real browsers and mobile devices for testing, along with test management, accessibility testing, load testing, and automation capabilities. Users can run tests in parallel across multiple device and browser combinations. It is indexed under Testing Tools.","source":"https://www.browserstack.com/support/plans-pricing","question":"What is BrowserStack?","confidence":0.6},{"answer":"BrowserStack offers a free tier, so you can start without paying. Paid plans start at $1099 per month. Pricing changes often, so verify at source before relying on it.","source":"https://www.browserstack.com","question":"Is BrowserStack free?","confidence":0.6},{"answer":"BrowserStack supports the web, Windows, iOS, Android and a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.","source":"https://www.browserstack.com/support/plans-pricing","question":"What platforms does BrowserStack support?","confidence":0.6},{"answer":"We have only confirmed a cloud / SaaS deployment for BrowserStack, so it appears to be vendor-hosted. If a self-hosted option exists we have not found it documented publicly.","source":"https://www.browserstack.com/support/plans-pricing","question":"Can BrowserStack be self-hosted?","confidence":0.6},{"answer":"We have independently confirmed SOC 2 and GDPR for BrowserStack. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as BrowserStack not holding them. Always confirm compliance directly before you rely on it.","source":"https://www.browserstack.com/security","question":"What security certifications does BrowserStack have?","confidence":0.7}]` | `[{"answer":"Vitest is a testing framework designed specifically for projects built with Vite. It reuses Vite's configuration and build plugins, eliminating duplicate setup when your application and tests share the same build pipeline. Developers using Vite benefit from streamlined testing without configuration overhead, though Vitest also works with projects that don't use Vite.","source":"https://vitest.dev","question":"What is Vitest and who should use it?","confidence":0.95},{"answer":"Yes, Vitest natively supports ESM, TypeScript, and JSX without requiring additional configuration or build steps. The framework automatically recognizes these modern JavaScript features through its integration with Vite's transformation pipeline, reducing setup complexity for developers working with contemporary toolchains.","source":"https://vitest.dev","question":"Does Vitest support TypeScript, JSX, and modern JavaScript out of the box?","confidence":0.95},{"answer":"Vitest's watch mode intelligently reruns only the tests affected by changes in your code, similar to how Vite's Hot Module Reload works for development. This approach is faster than manually filtering tests or waiting for full test suite reruns after each edit, improving developer experience during development cycles.","source":"https://vitest.dev","question":"How does Vitest's watch mode differ from other test runners?","confidence":0.92},{"answer":"Yes, Vitest includes a browser mode that executes tests in real browsers using Playwright (supporting Chromium, Firefox, and WebKit) or WebdriverIO (supporting Chrome, Firefox, Edge, and Safari). This enables genuine DOM interaction testing, component testing, and visual regression detection rather than relying on DOM simulation.","source":"https://vitest.dev/guide/browser.html","question":"Can I run tests in actual browsers with Vitest?","confidence":0.93},{"answer":"Vitest provides API compatibility with Jest, including support for `expect()` assertions, snapshot testing, and mocking. This makes it a potential drop-in replacement for Jest projects, though Vitest is optimized for Vite-based applications and may require configuration adjustments if your project uses other build systems.","source":"https://vitest.dev/guide/comparisons.html","question":"Is Vitest compatible with Jest, and can I migrate from Jest?","confidence":0.91},{"answer":"Vitest supports two coverage providers: V8 (native, faster, lower memory usage) and Istanbul (works with any JavaScript runtime but slower). Both providers generate multiple report formats including HTML, text summaries, and LCOV, and allow filtering which files to include or exclude from coverage calculations.","source":"https://vitest.dev/guide/coverage.html","question":"What code coverage options does Vitest provide?","confidence":0.93},{"answer":"Vitest requires Node.js version 20 or later and Vite version 6 or later. It can be installed and run through common package managers including npm, yarn, pnpm, and bun, making it accessible to most JavaScript development environments.","source":"https://vitest.dev/guide/","question":"What are Vitest's system requirements and minimum dependencies?","confidence":0.94},{"answer":"Yes, Vitest is completely free and open-source, maintained by a community of contributors with support from corporate sponsors. There is no licensing cost, commercial licensing model, or requirement to pay for core features or basic usage.","source":"https://vitest.dev","question":"Is Vitest free and open-source?","confidence":0.94}]` |
