The Testing Tool Kiro Can Drive Itself
Seamlessly Integrates With Your Favorite AI-Powered Editors
One Command to Onboard
testsprite setup --agent kiro configures your API key, verifies it, and drops a verification skill into your repository. Kiro learns the loop once instead of re-deriving it from documentation every session. Installation is purely local.
Tests Without Browser Code
A test is a plain-language plan file with action and assertion steps — no selectors to maintain, nothing that breaks on the next redesign. testsprite test create --plan-template prints a schema-correct skeleton pinned to your installed version.
One Failure Bundle, Not Five Artifacts
test failure get returns the failing step, its neighbours, screenshots, DOM snapshots, the test source, a root-cause hypothesis, and a recommended fix target — all sharing one snapshot id. The CLI refuses to stitch data from two different runs.
A Suite That Outlives the Context Window
Every passing test is banked. The requirement keeps being checked next session, next refactor, and after Kiro has long forgotten why it mattered — which no context window, however large, can do.
Let Kiro Verify Its Own Work
Generation is fast; review is the bottleneck. Give Kiro a way to prove a change works before it opens a pull request, and the diff stops being something a human has to read line by line.
Built for Teams Shipping Kiro Code
Free to Install, Open Source
The CLI is Apache-2.0 on GitHub and free to install from npm. Requires Node 20.19+, 22.13+, or 24+. Test execution runs in the cloud and consumes workspace credits.
Works Non-Interactively
TESTSPRITE_API_KEY=sk-... testsprite setup --from-env --yes --agent kiro never prompts, which is what an agent loop and a CI job both need.
Safe to Explore
--dry-run exercises the full code path offline with canned data. test scaffold and test lint never touch the network or your credentials at all.
Scriptable by Contract
A stable --output json shape and documented exit codes: 0 passed, 1 failed, 3 auth, 12 out of credits. A broken feature and a broken pipeline are distinguishable.

FAQ
How does TestSprite work with Kiro?
Run testsprite setup --agent kiro once. It installs a verification skill file into your repository describing the commands, the JSON shapes, and the exit codes, so Kiro can create, run, and triage tests on its own. Kiro is one of the harnesses the CLI installs skills for, so no bespoke integration is needed.
Does Kiro have to write browser automation code?
No. Tests are plain-language plan files with action and assertion steps. Run testsprite test create --plan-template for a schema-correct skeleton, or ask TestSprite to propose the first set with testsprite test plan generate — proposals are staged for review and nothing is written to disk until you accept them.
What exactly does TestSprite test?
Web application UI in a real cloud browser, and backend APIs. It does not drive native iOS or Android UI, desktop applications, or emulators. If your product has a web frontend or an HTTP API, that is what we cover.
Is it free, and is it open source?
The open-source CLI is free to install from npm and Apache-2.0 licensed. Running tests executes in TestSprite's cloud and consumes workspace credits — 0.5 per frontend run, 0.2 per backend run. There is a free community tier to start on.
Why not just let Kiro run unit tests?
Unit tests verify the implementation against your intent. An end-to-end run verifies the deployed product against a user's intent. A spec-driven workflow benefits from both, because a spec that passes in isolation can still ship a broken flow.
Can tests be written from a spec document?
Yes. Upload an API spec or PRD as a project source with testsprite project docs upload, then testsprite test plan generate drafts test cases from it and stages them for review. An API spec is free to upload; a PRD bills 0.5 credits for its embedding.
