PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 1 🔵⚪⚪⚪⚪

🧪 No relevant tests

🔒 Security concerns Command Injection: The code executes shell commands using subprocess.run() with shell=True, which could be vulnerable to command injection if the namespace or name parameters are user-controlled input. Although this is a test script, it's still a security best practice to avoid shell=True when possible.

⚡ Recommended focus areas for review Error Handling The stdout join operation is performed without checking if result.stdout exists or is not None. This could raise an AttributeError if the command fails. result = " ".join(result.stdout.splitlines())

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Security	Avoid shell injection vulnerabilities by not using shell=True in subprocess calls Using shell=True with subprocess.run can be a security risk as it processes the command through a shell - consider using a list of arguments instead. tests_scripts/kubernetes/base_k8s.py [770] -result = subprocess.run("kubectl get pods -A", timeout=300, shell=True, text=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) +result = subprocess.run(["kubectl", "get", "pods", "-A"], timeout=300, shell=False, text=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) Apply this suggestion Suggestion importance[1-10]: 9 Why: Using shell=True in subprocess calls is a significant security vulnerability that could allow command injection attacks. The suggestion properly addresses this by using a list of arguments instead, which is the secure way to execute commands.	9
Possible issue	Add error handling for subprocess command execution to prevent silent failures Add error handling for the subprocess.run command to handle potential command execution failures and check result.stderr for error messages. tests_scripts/kubernetes/base_k8s.py [770-771] result = subprocess.run("kubectl get pods -A", timeout=300, shell=True, text=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) +if result.returncode != 0: + Logger.logger.error(f"Failed to get cluster state: {result.stderr}") + raise Exception(f"kubectl command failed with error: {result.stderr}") result = " ".join(result.stdout.splitlines()) Apply this suggestion Suggestion importance[1-10]: 8 Why: The suggestion adds crucial error handling for the subprocess command, preventing silent failures and providing clear error messages when kubectl commands fail. This is important for debugging and system reliability.	8
