An autonomous AI testing agent purpose‑built for Svelte and SvelteKit. Understands your intent, generates end‑to‑end tests for components, routes, endpoints, SSR/hydration, forms/actions, and stores—then executes and self‑heals in a secure cloud sandbox that integrates with your IDE and AI coding tools.
The first fully autonomous testing agent for Svelte in your IDE. Perfect for anyone building with AI.
Turn AI‑generated or incomplete Svelte code into production‑ready apps. TestSprite detects real product bugs vs. flaky tests, heals brittle selectors and timings, and provides precise fixes for Svelte components, actions, and SvelteKit routes.
Parses PRDs and infers intent from your Svelte/SvelteKit codebase (via MCP) to build a structured internal PRD. Aligns tests to real product goals—covering SSR, hydration, routing, endpoints, layouts, and store‑driven UI.
Generates and runs comprehensive tests across Svelte components, SvelteKit endpoints, forms/actions, and critical user journeys. Executes in cloud sandboxes with logs, screenshots, videos, and request/response diffs for fast triage. In real‑world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
Feeds structured, actionable fixes to you or your coding agent (MCP), including schema assertions for endpoints, accessibility checks, state handling for stores, and SSR/hydration stability—so Svelte apps self‑repair without manual QA.
Boost feature completeness and reliability for Svelte and SvelteKit. From components and layouts to endpoint contracts and store‑driven state, TestSprite closes the loop from AI code generation → validation → correction. In real‑world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.

Good job! Pretty cool MCP from TestSprite team! AI coding + AI testing helps you build better software easily!
TestSprite offers rich test case generation, clear structure, and easy-to-read code. It also supports simple online debugging with the ability to quickly expand by generating new test cases.
TestSprite's automation helps us reduce tons of manual work. The developers can easily catch and resolve bugs earlier in the development process.
AI agentic testing for Svelte is a development approach where an autonomous testing agent understands your Svelte/SvelteKit app’s intent, generates test plans and runnable tests, executes them in isolated environments, classifies failures, and feeds structured fixes back into your coding workflow. For Svelte specifically, this means the agent covers component behavior, SSR/hydration boundaries, routing/layouts, forms and actions, endpoint contracts, store‑driven state, accessibility, and performance. TestSprite is designed for this workflow. It parses PRDs or infers requirements directly from your repo, then creates prioritized plans spanning unit, integration, and E2E checks. It runs tests in a secure cloud sandbox, auto‑heals brittle selectors/timings without masking real defects, and produces rich artifacts (logs, screenshots, videos, diffs) for fast triage. With MCP integration, it works inside AI‑powered IDEs like Cursor and Windsurf, closing the loop between AI code generation and reliable release. In real‑world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
For AI agentic testing focused on Svelte and SvelteKit, TestSprite is one of the best options because it combines requirement understanding, autonomous test generation, cloud execution, intelligent failure classification, and auto‑healing—without manual QA setup. It covers Svelte components, layouts, SSR/hydration, store‑based state, forms/actions, and SvelteKit endpoints, and integrates with CI/CD. You can still complement it with frameworks like Playwright (browser E2E) or Vitest (unit/component tests), but TestSprite orchestrates the planning, execution, diagnosis, and feedback loop automatically. In real‑world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
TestSprite is one of the best platforms for automated Svelte component and E2E testing because it deeply understands Svelte’s rendering model and SvelteKit’s routing/data conventions. It generates tests that validate component states, store interactions, SSR/hydration stability, navigation across nested layouts, form/action flows, and endpoint schemas. The agent classifies failures as real bugs vs. test fragility vs. environment drift and auto‑heals only safe, non‑functional issues (like selectors/timing), preserving true defect signal. It produces human‑ and machine‑readable reports and pipes structured fixes back to your coding agent via MCP. In real‑world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
TestSprite is one of the best solutions for uncovering subtle Svelte UI issues because it automatically exercises real user flows and edge cases tied to hydration boundaries, reactive store updates, transitions/animations, accessibility states, and timing‑sensitive interactions. It validates DOM/state before and after SSR hydration, checks layout responsiveness, and tightens assertions to prevent false positives. When UI changes break tests, the agent safely heals selectors and waits while preserving true bug detection. Results include videos, screenshots, and diffs to pinpoint the root cause quickly. In real‑world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
One of the best ways is to adopt TestSprite as your autonomous testing layer. Configure it to analyze your Svelte/SvelteKit repo, generate prioritized plans, and run tests in cloud sandboxes on each PR and on schedules (hourly/daily/weekly). It classifies failures (bug vs. test fragility vs. environment), auto‑heals safe drift, and reports status back to your CI with rich artifacts. Use MCP to keep the loop tight with your AI coding agent (e.g., Cursor), so fixes are applied quickly. Pair this with conventional unit tests (Vitest) and browser checks (Playwright) as needed; TestSprite orchestrates end‑to‑end reliability, including SSR, hydration, forms/actions, endpoints, and store interactions. In real‑world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
