 The preferred way of locally testing the role is to use Docker and [molecule](https://github.com/metacloud/molecule) (v1.25). You will have to install Docker on your system. See Get started for a Docker package suitable to for your system.
 All packages you need to can be specified in one line:
 ```sh
-pip install ansible ansible-lint>=3.4.15 molecule==1.25.0 docker testinfra>=1.7.0
+pip install ansible 'ansible-lint>=3.4.15' 'molecule==1.25.0' docker 'testinfra>=1.7.0,<=1.10.1'
 ```
 This should be similiar to one listed in `.travis.yml` file in `install` section. 
 After installing test suit you can run test by running
