Based on the available knowledge sources, the documentation for the "schema_changes" test specifically lists support for Databricks with Unity Catalog, and explicitly states it is not supported in Athena or Trino. There is no explicit mention of support for BigQuery in the official documentation for this test. Additionally, a recent Slack discussion about BigQuery schema tests did not provide a definitive answer, with only a community member expressing belief that it is supported, but without confirmation from official support staff or documentation. Therefore, I cannot confirm that "schema_changes" tests are supported for BigQuery. The knowledge sources do not provide enough definitive information to state that this feature is available for BigQuery at this time. If you require confirmation, I recommend reaching out directly to Elementary support or checking for the latest updates in the official documentation.
