Test Wikidata on tarkoitettu kehittäjille, jotta he voivat testata koodejaan ilman, että he rikkovat koko Wikimediaa, ja huuhtovat maailman mukanaan.
The Test Wikidata may also be used in a classroom environment for teaching basic Wikidata editing to avoid the great confusion resulting from creating pages and breaking a regular project, although this may not always be desirable because of the occasional difference between the test interface and a typical Wikimedia project interface.
