Molecule complaining about "[703] Should change default metadata: description" while running the basic test

Question

I couldn't run the molecule test command as it throws below error, while I can run individual commands without any errors ( Also provided --debug o/p below)

[701] Role info should contain platforms
/root/.config/pip/molecule-testing/meta/main.yml:1
{'meta/main.yml': {'__file__': u'/root/.config/pip/molecule-testing/meta/main.yml', u'dependencies': [], u'galaxy_info': {u'description': u'your description', u'license': u'license (GPLv2, CC-BY, etc)', u'author': u'your name', u'company': u'your company (optional)', u'galaxy_tags': [], '__line__': 2, '__file__': u'/root/.config/pip/molecule-testing/meta/main.yml', u'min_ansible_version': 1.2}, '__line__': 1}}

however if I run below commands it works perfectly. So, can anyone points out why whole test is failing, what should I do?

An error occurred during the test sequence action: 'lint'. Cleaning up.

TLDR;

These are errors/good practices reported by ansible-lint that you should fix. You can run the lint stage by its own by simply launching molecule lint.

From your current output, you only need to add some info in meta/main.yml in your role.

What is happening exactly

Each molecule command (e.g. converge, create, destroy, test...) launches a series of steps (a sequence) on your role. You can see the list of steps in the output of the command as in the following example taken from your question when you ran converge:

└── default
    ├── dependency
    ├── create
    ├── prepare
    └── converge

Those sequences are configured by default but can be customized in molecule.yml in your scenario directory. You can have a look at a customization on an open source role I maintain if you are interested in the subject.

By default, a converge sequence does not contain a lint stage. So you can run your test playbook without having to verify everything.

On the other hand, the test sequence includes all of the following steps:

└── default
    ├── lint
    ├── dependency
    ├── cleanup
    ├── destroy
    ├── syntax
    ├── create
    ├── prepare
    ├── converge
    ├── idempotence
    ├── side_effect
    ├── verify
    ├── cleanup
    └── destroy

As you can see, the first is lint, which (by default again) should run yamllint on all your yml files, followed by ansible-lint on your role and test playbook and finally flake8 on your python files (testinfra tests, custom modules, custom plugin filters...).

Your full test fails because the best practice checker ansible-lint is reporting problems that you should fix. From what I can see they are quite trivial and should go away with a couple lines in your meta/main.yml
