Reliable interface work

The other system is not ready? Keep testing.

Mock API endpoints return the responses your test needs.

Set the status code, headers and response body. Simulate delays before the real destination system is available.

Workflow

Run integration tests without a real target system

Fully Configurable

Set response codes, headers, body and authentication individually – for each endpoint.

Sync & Async

Choose response mode: immediate response or simulated delay for realistic scenarios.

Repeatable Test Cases

Save mock URLs and response rules to reproduce test cases at any time.

In practice

Send an order. Control the response.

Your integration sends orders to an API still in development. The expected response is already defined.

Create a mock endpoint and configure the status code and JSON response for your test case.

Test an error status or a delayed response alongside the successful case.

Saved response rules make these situations repeatable. I/O endpoints are available as an add-on.
