/dbt-test - Run dbt Tests

Visual Output

When executing this command, display the plugin header:

┌──────────────────────────────────────────────────────────────────┐
│  📊 DATA-PLATFORM · dbt Tests                                     │
└──────────────────────────────────────────────────────────────────┘

Then proceed with the tests.

Execute dbt tests with formatted pass/fail results.

Usage

/dbt-test [selection] [--warn-only]

Workflow

1. Pre-validation (MANDATORY):

   • Use dbt_parse to validate project first
   • If validation fails, show errors and STOP

2. Execute tests:

   • Use dbt_test with provided selection
   • Capture all test results

3. Format results:

   • Group by test type (schema vs. data)
   • Show pass/fail status with counts
   • Display failure details

Examples

/dbt-test                          # Run all tests
/dbt-test dim_customers            # Tests for specific model
/dbt-test tag:critical             # Run critical tests only
/dbt-test +fct_orders              # Test model and its upstream

Test Types

Schema Tests

Built-in tests defined in schema.yml:

• unique - No duplicate values
• not_null - No null values
• accepted_values - Value in allowed list
• relationships - Foreign key integrity

Data Tests

Custom SQL tests in tests/ directory:

• Return rows that fail the assertion
• Zero rows = pass, any rows = fail

Exit Codes

Code	Meaning
0	All tests passed
1	One or more tests failed
2	dbt error (parse failure, etc.)

Available Tools

Use these MCP tools:

• dbt_parse - Pre-validation (ALWAYS RUN FIRST)
• dbt_test - Execute tests (REQUIRED)
• dbt_build - Alternative: run + test together
