ResultManager

ResultManager()

Helper to manage Test Results and generate reports.

Examples

Create Inventory:

    inventory_anta = AntaInventory.parse(
        filename='examples/inventory.yml',
        username='ansible',
        password='ansible',
    )

Create Result Manager:

    manager = ResultManager()

Run tests for all connected devices:

    for device in inventory_anta.get_inventory().devices:
        manager.add(
            VerifyNTP(device=device).test()
        )
        manager.add(
            VerifyEOSVersion(device=device).test(version='4.28.3M')
        )

Print result in native format:

    manager.results
    [
        TestResult(
            host=IPv4Address('192.168.0.10'),
            test='VerifyNTP',
            result='failure',
            message="device is not running NTP correctly"
        ),
        TestResult(
            host=IPv4Address('192.168.0.10'),
            test='VerifyEOSVersion',
            result='success',
            message=None
        ),
    ]

The status of the class is initialized to “unset”

Then when adding a test with a status that is NOT ‘error’ the following table shows the updated status:

Current Status	Added test Status	Updated Status
unset	Any	Any
skipped	unset, skipped	skipped
skipped	success	success
skipped	failure	failure
success	unset, skipped, success	success
success	failure	failure
failure	unset, skipped success, failure	failure

If the status of the added test is error, the status is untouched and the error_status is set to True.
