Usage

On Python => 2.7 run python -m bats

On Python <2.7 (POD it is 2.6) run python -m bats.__main__

There are four actions supported:

Metadata : Reads a metadata.json file that contains the configuration of tests to execute
Compare : Compares two files that are provided as command-line arguments
Extract : Extracts a property from a file

Params:#

Pass metadata.json

$ python -m bats metadata metadata.json

Pass dynamic values - Pass dynamic values that will be replaced in the metadata.json. For example if I execute below command,

$ python -m bats metadata metadata.json -D key=value

Then, it will replace ${key} with 'value' in below metadata.json

{
    "name": "Demonstrate dynamic value"
    "tests": [
        {
            "name": "Sample test",
            "checks": [
                {
                    "name": "Sample check",
                    "source": {
                        "property": "${key}"
                        "type": "..."
                        "file": "..."
                    }
                    "target": {
                        "property": "${key}"
                        "type": "..."
                        "file": "..."
                    }
                }
            ]
        }
    ]
}
