Workflow

Run integration tests with realistic data

Flexible Data Types

Freely define fields with data type, required status and uniqueness – output in XML, JSON or SQL.

Targeted Error Cases

Generate proportional error cases to test interfaces and imports under realistic conditions.

Webhook Control

Send generated data directly to a webhook and inspect headers and payload in real time.

In practice

Missing a required field? Test it deliberately.

A new import must detect incomplete records. One valid example is not enough to test it.

Define the fields in the test data generator and generate a selected proportion of invalid records.

Send the sample data to the webhook and inspect the headers and content that arrive.

See exactly what was transmitted. Test data and webhook features depend on your plan and add-ons.
