End to end testing that validates your backend, not just the UI

Stop shipping broken logic behind pretty screens. Quash combines api testing and UI checks in one execution flow, so every release is validated end to end.

What Quash does

End to end testing, with backend validation in the same run

Quash combines UI execution with api testing in one flow. Teams get end to end software testing coverage that verifies user actions and backend responses together, with no test handoff to separate tools.

01 / API

API testing built into every mobile test run

Trigger endpoint checks at the exact step where the UI action happens. Quash validates status codes, response payloads, and key fields in context, so API test automation lives inside real release validation, not in a separate tool.

02 / Coverage

End to end testing automation across UI and backend

Replace disconnected checks with one execution loop that confirms frontend behavior, API contracts, and backend side effects together. Your team gets faster debugging context and stronger confidence in production releases.

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

End to end testing across dev, staging, and production-like stacks

Run the same backend validation rules across dev, staging, and production-like environments. Environment-specific connections let teams switch targets without rewriting tests.

Reusability

Reuse api testing checks across every critical flow

Define api testing checks once and reuse them everywhere. Centralized updates mean endpoint changes do not force test-by-test rewrites.

Control

Control end to end testing automation at each step

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

Test sync

API test automation triggered inside user flows

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

Visibility

Test API endpoints with precise assertions

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