The point: The datasette-fixtures plugin uses the populate_fixture_database() API to quickly generate test environments for plugin tests.
The datasette-fixtures 0.1a0 plugin provides a documented API to create test databases in Datasette and its plugin suites. The new component enables simple testing without prior Datasette installation.
With Datasette 0.0414, the helper function populate_fixture_database(conn) was newly documented. This creates the fixture database tables that Datasette’s own test suites use. The new plugin datasette-fixtures makes this API accessible to plugin developers.
The application is straightforward: With uvx, the plugin can be loaded directly without separate Datasette installation. The command uvx –prerelease=allow –with datasette-fixtures datasette –get /fixtures/roadside_attractions.json loads a sample database with entries about roadside attractions (such as “The Mystery Spot” in Santa Cruz and the “Winchester Mystery House” in San Jose with geographic coordinates).
For plugin developers, datasette-fixtures simplifies writing test suites, since the fixture database is provided via the standardized API and does not need to be maintained manually.
