# Quality and performance

> Review the testing, performance, and resilience standards every plugin must meet to be approved for the Lerian Marketplace — coverage, load, and SLO targets.

Plugins in the Lerian ecosystem must demonstrate high standards of quality and resilience. Testing and performance are non-negotiable requirements to ensure reliability for shared clients in production.

This section defines the minimum expectations every partner solution must meet before being approved for the Lerian Marketplace.

### Related practices

For faster client adoption, we strongly recommend providing SDKs in popular languages. While not required, SDKs help reduce integration errors and improve developer experience.

<Tip>
  Refer to the [SDK Guidelines](/en/partners-hub/sdk-guideline) for best practices.

## Testing standards

***

Your plugin must demonstrate:

* **≥ 90% unit test coverage**
* Integration and contract tests for external systems
* A visible test coverage report

<Tip>
  We also recommend automated CI/CD checks, linting, and peer reviews.
</Tip>

## Performance testing

***

Performance testing is **mandatory**. Your plugin must be:

* Stateless and horizontally scalable
* Resource-efficient (CPU, memory, connections)
* Fault-tolerant and high availability ready

<Warning>
  A stress test report must be included in the repository.
