A failed data-quality test should trigger investigation, not an automatic release decision. Block promotion when a failure breaks an important invariant or makes published data materially unsafe or misleading; let lower-risk failures proceed only as visible, owned warnings with a documented follow-up. In dbt, severity settings and isolated CI runs can support this policy, but your team must decide which checks are release-critical.
Decide what a failure means before it happens
For each test, record the invariant it protects, the models or tables and consumers affected, the expected response, and an owner. Reserve a blocking gate for failures that make a release unsafe or materially misleading—for example, a broken key or relationship assumption on which a published model depends. A low-impact anomaly may be allowed to proceed with visibility and follow-up, but it is still a failure, not a pass.
Common dbt built-in tests check uniqueness, non-nullness, accepted values, and relationships. Their importance depends on how the data is used: a missing value in a required customer identifier may be release-critical, while an out-of-range value in a nonessential reporting field may warrant investigation without stopping promotion. These are policy examples, not universal thresholds; dbt documents configuration options, not one cutoff that fits every system. See dbt’s severity configuration.
Choose blocking errors and advisory warnings
In dbt, a test’s severity can be set to error or warn; error and warning thresholds can further shape when a test is reported as an error or warning. dbt Labs describes warnings as allowing a run to continue and errors as stopping it. Those outcomes are tool behavior; they do not determine whether your organization should permit a production release. Define that separately in your release policy. The dbt configuration reference explains the options.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Severity can also vary by environment when the consequences justify it. The dbt-project-evaluator guide shows a pattern that warns by default and overrides severity to error in CI using an environment variable. Treat this as an example, not a default to copy blindly: decide whether CI and production need the same thresholds, and ensure that an advisory result remains visible to the people responsible for it.
Run pull-request checks in an isolated scope
Use CI to validate the changed work without confusing a pull-request check with a full production run. dbt’s CI guidance describes building and testing changed assets and relevant downstream dependencies in a temporary schema, then reporting results on the pull request. This helps isolate proposed changes from shared production objects. Repository merge protections can require the checks designated as mandatory while leaving advisory checks visible but non-blocking. See dbt’s continuous integration guidance.

Keep development and production targets separate, review changes before promotion, and test assumptions about both transformations and source data. Use broader full-project validation when the assurance you need extends beyond the modified graph. Snowflake’s guidance for dbt CI/CD on Snowflake also distinguishes full-project validation from selected modified-graph CI. This workflow advice is specific to the documented dbt patterns; other databases, orchestrators, and test frameworks need equivalent controls verified in their own documentation.
Triage the failure before deciding whether to release
- Inspect the test and its evidence. Review the compiled test query and the rows it returns. dbt data tests produce failure rows; stored failures can make inspection easier, and custom tests can return identifying columns when the default output lacks context. Stored results for a test replace that test’s previous stored results, so copy or retain evidence elsewhere if an incident record must persist. See dbt’s data test documentation.
- Check whether the failure is new and reproducible. Establish whether it appeared with the proposed code, reflects existing data behavior, or comes from an execution or configuration problem. Compare the failure with the invariant and the affected consumers rather than treating every failing row as equivalent.
- Check upstream data and scope. A failed check can be unrelated to the changed code. dbt’s workflow guidance describes failures unrelated to modified or error nodes, including a source test that may need a refreshed load. Diagnose and document that case; refresh or correct the upstream input and rerun the relevant check rather than silently waiving it. See dbt’s CI workflow guidance.
- Assign a disposition. For a failure allowed to proceed, record the test, affected model or table, failing-row count or sample when available, likely cause, severity, owner, release decision, exception rationale if applicable, and remediation due date. This record is an operational recommendation, not a vendor-prescribed schema; its purpose is to keep a warning from becoming an unowned permanent exception.
Make the release decision explicit
- Block promotion when a high-impact invariant fails and the release would be unsafe or materially misleading. Fix the issue, or use only an authorized, documented exception under your team’s policy.
- Proceed with visibility when the risk is acceptable under policy. Show the warning in the pull request or release record and create a tracked follow-up with an owner and due date.
- Do not hide the result. Avoid broadly disabling tests or excluding failures without a named reason and review. dbt’s workflow examples include selecting failed tests and excluding a known example; such mechanics should be paired with explicit exception ownership.
When comparing possible dispositions, ask whether the failed invariant could harm downstream use, whether the failure is in changed code or unrelated source data, whether CI isolated the check in a temporary schema, whether any warning remains visible and owned, and whether the returned evidence is sufficient to diagnose the problem.

Apply the policy beyond dbt carefully
The severity settings, failure-result behavior, and temporary-schema CI pattern described here are dbt-specific. The available documentation supports these dbt workflows and Snowflake’s dbt guidance; it does not establish portable syntax, rollback behavior, or release-gating rules for every database, orchestration system, or testing framework. For other tools, verify their own documentation for equivalent severity controls, isolated validation, failure evidence, and merge or deployment gates before adopting the same process.
