Stop shipping broken logic behind pretty screens

Connection

Simple steps, confident tests

Setup validations with few simple steps, and become confident with releases

Connect your backend - API connections

Connect your backend

Enter base URL and auth (e.g. add your API token), then choose an authentication method. Quash supports No Auth, Bearer Token, API Key or any Custom Header needed for your API.

Add validations - API endpoint

Add validations

Pick an endpoint (GET, POST, etc.), set the expected response and define what success looks like. You can add JSONPath or Regex checks and mark important ones as "Required" to fail the test if they break.

Run your tests - test report

Run your tests

Quash runs backend checks right after the related UI actions — automatically or via @in prompts. Results show up with full request/response logs in the test report, so you know what passed or failed instantly.

Capabilities

Backend checks that run when the UI does — not after.

Plan, track, and run tests with full visibility while staying aligned with product and tools.

Environment

Multi-environment coverage

Run the same backend validations across dev, staging, or production. Environment-specific connections let you switch targets without rewriting tests.

Multi-environment coverage
Reusability

Reuse validations everywhere

Define a backend validation once and reuse it everywhere. Central management means API changes don't force test-by-test updates.

Reuse validations everywhere
Control

Full execution control

Control when and how validations run. Set required vs optional checks, timeouts, retries, and execution timing within a test.

Full execution control
Test sync

Backend checks in flow

Trigger backend validations directly inside natural-language test prompts, exactly when a UI action happens.

Visibility

Flexible response checks

Validate status codes, assert JSON fields with paths, match patterns using regex, or partially compare responses—only what matters.
