## Appendix II: Runtime Features
By default, the test validator runs with all [runtime features](programming-model/runtime#features) activated.
You can verify this using the [Solana command-line tools](cli/install-solana-cli-tools.md):
```bash
solana feature status -ul
```
Since this may not always be desired, especially when testing programs meant for deployment to mainnet, the CLI provides an option to deactivate specific features:
```bash
solana-test-validator --deactivate-feature <FEATURE_PUBKEY_1> --deactivate-feature <FEATURE_PUBKEY_2>
```
