The liquibase-snowflake extension now comes with integration test support via the liquibase-test-harness. This Liquibase test framework is designed to also make it easy for you to test your extensions.
We have provided a harness-config.yml file in src/test/resources directory.
This file should contain the connection information for all the databases you want the snowflake extension to be tested against.
Use harness.initScript.sql file to create and populate test database for harness integration tests
From your IDE, right click on the liquibase.ext.snowflake.SnowflakeChangeObjectIT test class present in src/test/groovy directory.
Doing so, will allow you to execute all the standard change object tests in the liquibase-test-harness as well as the
snowflake specific change objects tests created exclusively to test this extension (You can find this in the
src/test/resources/liquibase/harness/changelogs/snowflake directory).
