SMOKE_BLACK

SMOKE_BLACK load steps can be used to execute data smoke tests as part of load workflows. A SMOKE_BLACK test result will be logged, and a failure will also fail the workflow and stop any subsequent, dependent loads from executing to prevent errors from spreading.

Usage

SMOKE_BLACK: sql_code

Notes

A SMOKE_BLACK test fails if the test SQL returns any rows.

SMOKE_BLACK steps can be used alone or together with other load steps. They can also be used with automatically generated loads.

SMOKE_BLACK steps can be saved as part of a load template.

SMOKE_BLACK steps can use variables inside the SQL code.

Examples

Test to check whether duplicates exist target table

The following SQL uses variables, so the test can also be templated and used in similar tables without further modification. The SQL clause checks whether there are duplicates in the target table and stops the data load in case rows are found.

SMOKE_BLACK:

-- Duplicates Smoke Test
SELECT 
           COUNT(*) AS has_duplicates
FROM (
           SELECT
                       DV_ID, 
                       COUNT(1) AS cnt_rows
           FROM
                       <target_schema>.<target_entity_name>
           GROUP BY
                       DV_ID
           HAVING
                       COUNT(1) > 1
) t1
HAVING
           COUNT(*) > 0

Agile Data Engine executing the test for S_RATECODE entity in DV schema:

-- Duplicates Smoke Test
SELECT 
           COUNT(*) AS has_duplicates
FROM (
           SELECT
                       DV_ID, 
                       COUNT(1) AS cnt_rows
           FROM
                       DV.S_RATECODE
           GROUP BY
                       DV_ID
           HAVING
                       COUNT(1) > 1
) t1
HAVING
           COUNT(*) > 0
