limit

Limit the number of failures that will be returned by a test query. We recommend using this config when working with large datasets and storing failures in the database.

Specific test

Configure a specific instance of a generic (schema) test:

models/<filename>.yml

version: 2

models:
  - name: large_table
    columns:
      - name: very_unreliable_column
        tests:
          - accepted_values:
              values: ["a", "b", "c"]
              config:
                limit: 1000  # will only include the first 1000 failures

One-off test

Configure a one-off (data) test:

tests/<filename>.sql

{{ config(limit = 1000) }}

select ...

Generic test block

Set the default for all instances of a generic (schema) test, by setting the config inside its test block (definition):

macros/<filename>.sql

{% test <testname>(model, column_name) %}

{{ config(limit = 500) }}

select ...

{% endtest %}

Project level

Set the default for all tests in a package or project:

dbt_project.yml

tests:
  +limit: 1000  # all tests
  
  <package_name>:
    +limit: 50 # tests in <package_name>
