Testing guide

Testing changes to models

To run unit tests for your models, run the sqlmesh test command as follows:

$ sqlmesh test
Ran 1 test in 0.042s

As the unit tests run, SQLMesh will identify any that fail.

For more information about tests, refer to testing.

Test changes to a specific model

To run a specific model test, pass in the suite file name followed by :: and the name of the test; for example: sqlmesh test tests/test_suite.yaml::test_example_full_model.

Run a subset of tests

To run a test that matches a pattern or substring, use the following syntax: sqlmesh test tests/test_example*.

Running the above command will run our test_example_full_model test that we ran earlier using sqlmesh test:

$ sqlmesh test tests/test_example*
Ran 1 test in 0.042s


As another example, running the sqlmesh test tests/test_order* command would run the following tests:

  • test_orders
  • test_orders_takeout
  • test_order_items
  • test_order_type

Auditing changes to models

To audit your models, run the sqlmesh audit command as follows:

$ sqlmesh audit
Found 1 audit(s).
assert_positive_order_ids PASS.

Finished with 0 audit error(s).
Note: Ensure that you have already planned and applied your changes before running an audit.

By default, SQLMesh will halt the pipeline when an audit fails in order to prevent potentially invalid data from propagating further downstream. This behavior can be changed for individual audits by defining them as non-blocking.

For more information about audits, refer to auditing.
