protected function KernelTestBaseDatabaseDriverModuleTest::getDatabaseConnectionInfo in Drupal 9

Returns the Database connection info to be used for this test.

This method only exists for tests of the Database component itself, because they require multiple database connections. Each SQLite :memory: connection creates a new/separate database in memory. A shared-memory SQLite file URI triggers PHP open_basedir/allow_url_fopen/allow_url_include restrictions. Due to that, Database tests are running against a SQLite database that is located in an actual file in the system's temporary directory.

Other tests should not override this method.

@internal

Return value

array A Database connection info array.
