Indirect selection

Use the --indirect_selection flag to dbt test or dbt build to configure which tests to run for the nodes you specify. You can set this as a CLI flag or an environment variable. In dbt Core, you can also configure user configurations in YAML selectors or in the flags: block of dbt_project.yml, which sets project-level flags.

When all flags are set, the order of precedence is as follows. Refer to About global configs for more details:

1. CLI configurations
2. Environment variables
3. User configurations

You can set the flag to: empty, buildable, cautious, or eager (default). By default, dbt indirectly selects all tests if they touch any resource you select. Learn more about these options in Indirect selection in Test selection examples.

You can use the following modes to configure the behavior when performing indirect selection (with eager mode as the default). Test exclusion is always greedy: if ANY parent is explicitly excluded, the test will be excluded as well.

Building subsets of a DAG

The buildable and cautious modes can be useful when you're only building a subset of your DAG, and you want to avoid test failures in eager mode caused by unbuilt resources. You can also achieve this with deferral.

Eager mode

By default, runs tests if any of the parent nodes are selected, regardless of whether all dependencies are met. This includes ANY tests that reference the selected nodes. Models will be built if they depend on the selected model. In this mode, any tests depending on unbuilt resources will raise an error.

Buildable mode

Only runs tests that refer to selected nodes (or their ancestors). This mode is slightly more inclusive than cautious by including tests whose references are each within the selected nodes (or their ancestors). This mode is useful when a test depends on a model and a direct ancestor of that model, like confirming an aggregation has the same totals as its input.

Cautious mode

Ensures that tests are executed and models are built only when all necessary dependencies of the selected models are met. Restricts tests to only those that exclusively reference selected nodes. Tests will only be executed if all the nodes they depend on are selected, which prevents tests from running if one or more of its parent nodes are unselected and, consequently, unbuilt.

Empty mode

Restricts the build to only the selected node and ignores any indirect dependencies, including tests. It doesn't execute any tests, whether they are directly attached to the selected node or not. The empty mode does not include any tests and is automatically used for interactive compilation.

The following is a visualization of the impact --indirect-selection and the various flags have using three models, three tests, and dbt build as an example:

dbt build

Eager (default)

Buildable

Cautious

Empty

For example, you can run tests that only refer to selected nodes using a CLI configuration:

Usage

dbt test --indirect-selection cautious

Or you can run tests that only refer to selected nodes using an environment variable:

Env var

$ export DBT_INDIRECT_SELECTION=cautious
dbt run

You can also run tests that only refer to selected nodes using dbt_project.yml project-level flags:

dbt_project.yml

flags:
  indirect_selection: cautious
