Manufacturer / project: DTM soft

When does it fit?

Best for database QA teams needing configurable, schema-aware generation, repeatable runs, scrambling, and multiple outputs, provided the required runtime and edition fit their environment. 1 · 2 · 3

Fit still depends on your mandatory requirements.

What should you check before choosing?

Scrambling and bundled masking are Enterprise-only. Latest located release 3.02 dates to 2021; broad database access may use ODBC/OLE DB. Virtualization is undocumented. 1 · 2 · 3 · 4

What must your PoC prove?

Use a parent/child fixture, one invalid row and a fixed expected result. Check cleanup after failure, restore the configuration and repeat with pinned inputs. Unresolved requirements need a demonstration.

Acceptance plan, not a product test result. Execution scope and limits.

Deployment and license

Windows desktop application; the vendor also documents runtime and multiplatform-runtime licenses for executing projects on Unix/Linux and Mac OS. Standard, Professional, Enterprise, and runtime options have different features; CLI is Professional/Enterprise. 1 · 2 · 3 · 4

How you work with it
