# Validation and Testing

> Validate governance config and evaluate guardrail behavior.

Use these commands before promoting governance changes.

## 1) Validate configuration

```bash theme={null}
dazense validate
```

Checks consistency across:

* dataset bundles
* policy configuration
* semantic model references

## 2) Run governance evaluation

```bash theme={null}
dazense eval
```

Runs governance test cases from bundle `eval_test_cases`.

## 3) Run engine-based evaluation

```bash theme={null}
dazense eval --engine
```

Runs Python-native policy checks (stronger than structural heuristics):

* PII checks (including `SELECT *`)
* table scope detection
* time filter checks
* business-rule matching

## 4) Run scorecard only

```bash theme={null}
dazense eval --scorecard
```

Shows governance completeness checks (for example `require_contract`, bundle requirements, PII declarations).

## 5) Mode-based manual checks

For end-to-end UX validation, test each mode:

1. **none** — no governance
2. **semantic** — semantic model + business rules
3. **full** — policy + contracts + bundle constraints

Use your mode switch script and start a new chat after each switch.

## Minimum production bar

* `dazense validate` passes
* `dazense eval` passes
* `dazense eval --engine` passes
* PII prompts are blocked in full mode
* Critical metrics (for example revenue) are consistent across supported LLMs
