# Repository validation
This is where the validation rules that run against the various repository categories live.
## Structure
- All validation rules are in the directory for their category.
- Validation rules that aplies to all categories are in the `common` directory.
- There is one file pr. rule.
- All rule needs tests to verify every possible outcome for the rule.
- It's better with multiple files than a big rule.
- All rules uses `ValidationBase` or `ActionValidationBase` as the base class.
- The `ActionValidationBase` are for checks that will breaks compatibility with with existing repositories (default), so these are only run in github actions.
- The class name should describe what the check does.
- Only use `validate` or `async_validate` methods to define validation rules.
- If a rule should fail, raise `ValidationException` with the failure message.
## Example
```python
from custom_components.hacs.validate.base import (
ActionValidationBase,
ValidationBase,
ValidationException,
)
class AwesomeRepository(ValidationBase):
def validate(self):
if self.repository != "awesome":
raise ValidationException("The repository is not awesome")
class SuperAwesomeRepository(ActionValidationBase, category="integration"):
async def async_validate(self):
if self.repository != "super-awesome":
raise ValidationException("The repository is not super-awesome")
```
