export SNOWFLAKE_TEST_USER=<your_user>
export SNOWFLAKE_TEST_PASSWORD=<your_password>
export SNOWFLAKE_TEST_ACCOUNT=<your_account>
export SNOWFLAKE_TEST_WAREHOUSE=<your_warehouse>
export SNOWFLAKE_TEST_DATABASE=<your_database>
export SNOWFLAKE_TEST_SCHEMA=<your_schema>
export SNOWFLAKE_TEST_PROTOCOL=<your_snowflake_protocol>

Note it is not required to build a package to run tests blow.

Development

Reformat source code

Check formatting on all files:

npm run lint:check:all

Check formatting of single file or directory e.g. test/unit/snowflake_test.js:

npm run lint:check -- test/unit/snowflake_test.js

Fix potentially fixable formatting errors and warnings of single file or directory e.g. test/unit/logger:

npm run lint:fix -- test/unit/logger
