* Create database tables that a plugin needs on startup * Create database tables that a plugin needs on startup
* Validate the metadata configuration for a plugin on startup, and raise an error if it is invalid * Validate the metadata configuration for a plugin on startup, and raise an error if it is invalid
.. note::
If you are writing :ref:`unit tests <testing_plugins>` for a plugin that uses this hook you will need to explicitly call ``await ds.invoke_startup()`` in your tests. An example:
.. code-block:: python
@pytest.mark.asyncio
async def test_my_plugin():
ds = Datasette([], metadata={})
await ds.invoke_startup()
# Rest of test goes here
