+For Databricks integration tests, you need to set:
+
+```bash
+export DATABRICKS_JDBC_URL="jdbc:databricks://<workspace-url>:443/default;transportMode=http;ssl=1;httpPath=sql/protocolv1/o/<org-id>/<workspace-id>"
+export DATABRICKS_TOKEN="<your-databricks-token>"
+```
+
+You can get these values from your Databricks workspace:
+1. The JDBC URL can be found in the Databricks SQL endpoint connection details
+2. The token can be generated from your Databricks user settings
+
+After setting up the required environment variables, you can run the integration tests using:
+
+```bash
+./gradlew test
+```
+
+<!-- Note: Integration tests are skipped by default when running in smoke test mode (when `NXF_SMOKE` environment variable is set). -->
