The testing framework supports using your own GCS-compliant endpoint, by
setting the “STORAGE_EMULATOR_HOST” environment variable. If this is
not set, then an emulator will be spun up using
fake-gcs-server. This emulator has almost all the functionality of
real GCS. A small number of tests run differently or are skipped.
If you want to actually test against real GCS, then you should set STORAGE_EMULATOR_HOST to “https://storage.googleapis.com” and also provide appropriate GCSFS_TEST_BUCKET and GCSFS_TEST_PROJECT, as well as setting your default google credentials (or providing them via the fsspec config).
