 In order to run the molecule tests locally with python 3.9 available, after cloning the repository:
-
-```
-pip install yamllint 'molecule[docker]~=3.5.2' ansible-core flake8 ansible-lint voluptuous
-molecule test --all

-## Integration testing

-Demo repositories which depend on the collection, and aggregate functionality with other middleware_automation collections, are automatically rebuilt
-at every collection release to ensure non-breaking changes and consistent behaviour.

-The repository are:
-
- - [Flange demo](https://github.com/ansible-middleware/flange-demo)
-   A deployment of Wildfly cluster integrated with keycloak and infinispan.
- - [CrossDC keycloak demo](https://github.com/ansible-middleware/cross-dc-rhsso-demo)
-   A clustered multi-regional installation of keycloak with infinispan remote caches.
+The test scenarios are available on the source code repository each on his own subdirectory under [molecule/](https://github.com/ansible-middleware/keycloak/molecule).
