Prometheus: Add README for prometheus-test #9
Conversation
WalkthroughThis update introduces a comprehensive Prometheus Test Framework, including core classes, utilities, documentation, and configuration for automated testing of Prometheus tasks. It features multi-worker orchestration, MongoDB integration, cryptographic signing, and stateful test execution. Additionally, a new security and quality assessment report for the framework's worker management module is added. Changes

44-49: Whitelist insanitize_envmay be too restrictive
The example only allowsPYTHONUNBUFFERED,PORT, andDATABASE_PATH, but real worker processes often rely on additional environment variables (e.g.,WORKER_ID, DB credentials). Either make the allowed‐keys list configurable or explicitly document and expand it to cover all required variables.
136-145: Consider dependency and thread‐safety for readiness checks
Thewait_for_serversnippet uses blockingrequests.getandtime.sleep. If your framework spawns threads or async I/O, ensure this check runs before thread creation or refactor it to use non‐blocking/asynchronous calls (e.g.,aiohttp). Adding structured logging on each attempt will aid debugging.

🛠️ Refactor suggestion
Avoid fixed time.sleep for readiness checks
A hardcoded sleep(3) may cause race conditions or unnecessary delays. Replace it with the dynamic wait_for_server pattern (lines 136–145) which polls the endpoint, uses exponential backoff, and fails fast if the server never becomes ready.

Incorrect fallback in os.getenv for keypair paths
Using os.getenv(keypairs.get("staking"), f"{name.upper()}_STAKING_KEYPAIR") will return the literal string "<NAME>_STAKING_KEYPAIR" when the variable is unset, not a valid file path. This can lead to confusing errors or silent failures. Instead, derive the env‐var name first, then require it or raise if missing, for example:
env_var = keypairs.get("staking") or f"{name.upper()}_STAKING_KEYPAIR"
staking_keypair_path = os.getenv(env_var)
if not staking_keypair_path:
raise EnvironmentError(f"Missing staking key env var: {env_var}")| self.process = subprocess.Popen( | ||
| [sys.executable, str(self.server_entrypoint)], | ||

| ) | ||

🛠️ Refactor suggestion
Subprocess invocation requires tighter sanitization
The current use of subprocess.Popen opens the server with env=self.env, which may include unvalidated user‐controlled data. While passing args as a list avoids shell interpolation, environment values can still introduce risks. Implement strict validation or sanitization of both keys and values before assigning to self.env, and consider quoting any paths using shlex.quote if you ever pass strings to a shell.

🛠️ Refactor suggestion
Adopt graceful shutdown for worker processes
Relying on os.kill with a fixed sleep interval can orphan processes or leak resources. Prefer using process.terminate() followed by process.wait(timeout), then process.kill() on timeout, as shown in the terminate_process helper below. This approach is more robust and configurable.
