CI Automation Framework

[vitiral]

The test harness/framework in artifact-data is going quite well and I would like to do something similar for the CLI tools.

Basic design:

• An artifact project would be created normally. It can have assert_*.yaml files from the artifact-data test harness (which will be used and asserted)
• There will be an assert_cli.yaml file with the following structure:

-
    cmd: "<command to run>
    expect: "string to expect"
    expect_html: "alternatively, you can specify the string to expect in 'html->ansi format' and it will render it"
``

The harness will copy the folder to a temporary directory, run the commands and expect the results.
