Ansible role for tests using fontconfig

Put this role in your tests.yml playbook. The playbook will first install package dependencies listed on playbook on your localhost, then it will proceed to run testing. You can redefine the following variables:

• artifacts: An artifacts directory on localhost to store logs
• remote_artifacts: The directory on the system under test where the logs are stored. Note: if this variable is left undefined, it will default to /tmp/artifacts
• required_packages: A list of prerequisite packages required by tests. Please note that for Atomic Host, additional packages will be installed using the rpm-ostree command which is affecting the test subject (it's similar as rebuilding an rpm package to be tested) so this should be used with caution on only when necessary.
• path_prefix: The directory on the system where fonts are installed. please use one in coverage sub-parameter if having different path_prefix per sub-packages.
• package: The package name to test. this is used to find out fontconfig config file. please use one in families sub-parameter if having different config files per sub-packages.
• coverage: A list of languages for language coverage tests.
• families: A list of family test cases.

Language coverage test parameters

Supporting two types of formats. one is a simple list of languages:

coverage:
  - en
  - fr

Another one is a dictionary that has a language as a key and values as parameters:

coverage:
  en:
    ...
  fr:
    ...

You can redefine the following variables for dictionary format:

• exclude: A list of font file names to exclude on this testing. this is useful to avoid unexpected failures on iterating tests when a package has multiple font files and has different coverages but you need to prevent testing for few fonts which has different coverages to them. Please note that the file name is relative to path_prefix parameter. also good to consider using include if non-targeted files is more than targeted.
• include: A list of font file names to include on this testing. this is useful to avoid unexpected failures on iterating tests when a pcakge has multiple font files and has different coverages but you need to prevent testing for few fonts which has different coverages to them. Please note that the file name is relative to path_prefix parameter. also good to consider using exclude if targeted files is more than non-targeted.
• name: The name to store logs. the test script is trying to make an unique file names to store logs but not perfectly working in some cases. this is optional parameter to make it unique by yourself.
• path_prefix: A list of directory names where fonts are installed on system. this is optional parameter and tries to obtain the font paths from installed packages by required_packages if not available.

Family test parameters

• lang: A language to test family name for.
• alias: An alias name to test.
• family: A family name to test, which is supposed to be assinged to the alias.
• package: The package name to test. this is used to find out fontconfig config file. this is optional. if not specified here, global package parameter will be used.
