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.
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.
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.
Your end-to-end QA journey
Validate your backend with test-grade intelligence
API test automation, inside your end to end tests
End to end software testing from UI action to API response
Simple steps, confident tests
Setup validations with few simple steps, and become confident with releases
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
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.
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.
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.
Don't just take our word for it
Here's what people are saying about Quash
Shree Narayan Jha
Quash is a one of a kind innovation in the QA space - beneficial for individuals, organisations and learners alike. The app exploration is top notch. I'm impressed by how it bypasses obstacles and makes it easier to test specific features.
Rahul Suthar
I work with similar products and out of all of them, Quash is a really good tool. You can get a lot of testing covered with minimal effort.
Jwala Agrawal
Using Quash was like speaking to the tool. I said 'Download Amazon' and it went to the Play Store, downloaded it, launched the app and handled all the pop ups automatically. The best part is its intelligence.
