vault88 0.3.3

Python automated test framework

vault88

vault88 is a Python automated test framework designed for structured hardware and software validation in CI/CD pipelines. Tests are written as Python classes, organised into stages, and results can be published through configurable reporters.

Architecture

Component	Role
Loader	Discovers test classes from files or directories; supports tag-based include/exclude filtering
Logger	Centralised logging with rotating file handler and optional verbose (debug) output
Runner	Instantiates and executes a test class through its full lifecycle: selfCheck → setup → run → teardown
Reporter	Pluggable reporters loaded from the config file; built-in reporters include JUnit XML and log archive

Test results are grouped into named stages within each test, and each result records an action, expected value, actual value, outcome, timestamp, and optional requirement references.

Installation

pip install vault88

Or with uv:

uv add vault88

Writing a test

Subclass Test and implement the four lifecycle methods:

from vault88 import Test

class MyTest(Test):
    name = "My Test"
    tags = ["smoke"]

    def selfCheck(self) -> bool:
        # Return False to skip the test entirely
        return True

    def setup(self) -> bool:
        # Prepare resources; return False to abort
        return True

    def run(self) -> None:
        self.newStage("Basic checks")
        self.assertEqual("Verify result", expected=42, actual=compute())

    def teardown(self) -> None:
        pass

Available assertion helpers: assertEqual, assertNotEqual, assertTrue, assertFalse, assertGreaterThan, assertLessThan, assertGreaterThanOrEqual, assertLessThanOrEqual, assertIn, assertNotIn, assertIsNone, assertIsNotNone.

Running tests

vault88 <testpath> [options]

Option	Description
testpath	Path to a test file or directory
-t TAG [TAG ...]	Only run tests that have at least one of these tags
-nt TAG [TAG ...]	Exclude tests that have any of these tags
-r	Recursively search directories for tests
-l FILE	Log file path (default: ./test_execution.log)
-v	Verbose / debug logging
--env PATH_OR_URL	Load an environment from a JSON file or HTTP(S) URL
--junit	Generate a testresults.xml JUnit report in the current directory

Environments

An environment passes host addresses, service details, and credentials into tests at runtime so the same test class can run against different targets without code changes.

Environment file format

Environments are defined as JSON. The top-level hosts list is the main entry point; each host can carry services and credentials:

{
  "name": "staging",
  "hosts": [
    {
      "name": "app-server",
      "address": "10.0.1.10",
      "credential": {
        "username": "deploy",
        "key_path": "/home/ci/.ssh/id_rsa"
      },
      "services": [
        {
          "name": "api",
          "port": 8080,
          "url": "http://10.0.1.10:8080"
        }
      ]
    }
  ]
}

All fields other than name and address (on a host) are optional.

Loading an environment

Pass the file path or an HTTP(S) URL to --env:

# from a local file
vault88 tests/ --env ./staging.json

# from an API endpoint
vault88 tests/ --env https://inventory.example.com/envs/staging

The API loader expects the endpoint to return the same JSON structure.

Using the environment in a test

The loaded Environment object is available as self.environment. Walk the hosts list or look up a host by name:

from vault88 import Test

class DeploymentTest(Test):
    name = "Deployment smoke test"
    tags = ["smoke"]

    def selfCheck(self) -> bool:
        return self.environment is not None

    def setup(self) -> bool:
        return True

    def run(self) -> None:
        self.newStage("Connectivity")

        host = next(h for h in self.environment.hosts if h.name == "app-server")
        api = next(s for s in host.services if s.name == "api")

        response = requests.get(f"{api.url}/health")
        self.assertEqual("Health endpoint returns 200", expected=200, actual=response.status_code)

    def teardown(self) -> None:
        pass

Attribute	Type	Description
environment.name	str	Environment name from the JSON
environment.hosts	List[Host]	All hosts in the environment
host.name	str	Host label
host.address	str	IP address or hostname
host.credential	Credential | None	SSH or login credential for the host
host.services	List[Service]	Services running on the host
service.name	str	Service label
service.port	int | None	Port number
service.url	str | None	Full URL
service.credential	Credential | None	Service-specific credential
credential.username	str	Username
credential.password	str | None	Password
credential.key_path	str | None	Path to a private key file

Configuration

The config file is read from the first location found: --config PATH (CLI flag) → ~/.vault88.conf → /etc/vault88.conf. It uses INI format.

Console output

All terminal output is rendered through a console template. Configure it in the [CONSOLE] section of the config file.

Selecting a template

[CONSOLE]
template = default

Value	Effect
default (or omitted)	Use the built-in DefaultTemplate
mypackage.console.MyTemplate	Load a custom template class by its full dotted Python path

If the custom class cannot be imported, vault88 logs a warning and falls back to DefaultTemplate.

DefaultTemplate options

Key	Default	Description
width	auto-detected	Output width in characters (falls back to 80 if terminal detection fails)
stage_color	(none)	ANSI color applied to stage header lines
step_color	(none)	ANSI color applied to the Step N-N: prefix
timestamp_format	%H:%M:%S	strftime format string for step timestamps
timestamp_position	field	Where timestamps appear: field (own line) or inline (after step number)

Available color names: black, red, green, yellow, blue, magenta, cyan, white, bright_black, bright_red, bright_green, bright_yellow, bright_blue, bright_magenta, bright_cyan, bright_white.

[CONSOLE]
width = 120
stage_color = cyan
step_color = bright_blue
timestamp_format = %Y-%m-%d %H:%M:%S
timestamp_position = inline

See docs/console-templates.md for the full template API and a custom template example.

Reporters

Each [REPORTER<n>] section loads one reporter:

[REPORTER1]
module = vault88.core.reporters.junit_reporter
class = JUnitReporter
enabled = true
suite_name = My Project Tests

[REPORTER2]
module = vault88.core.reporters.log_archive_reporter
class = LogArchiveReporter
enabled = true
output_dir = ./logs
