How to Intentionally Keep an AWS EC2 Instance in the Pending State?

Hello =>You can follow this process if it suits to you: To keep the instance in pending state for Testing the application. =>By Creating a directory under you project code: my_project/ ├── my_app.py # Your application code └── tests/ └── test_my_app.py # Your test file (where the mocking code goes).

test_my_app.py **

from unittest.mock import patch
import boto3
from my_app import get_instance_status  # Your application code

@patch('boto3.client')  # Mock boto3.client
def test_pending_instance(mock_client):
    # 1. Get the mock EC2 client
    mock_ec2 = mock_client.return_value

    # 2. Create the mock response
    mock_response = {
        'Reservations': [{
            'Instances': [{
                'InstanceId': 'i-1234567890abcdef0',
                'State': {'Name': 'pending'},
                'Placement': {'AvailabilityZone': 'us-east-1a'}, # Add more attributes as needed
                'InstanceType': 't2.micro'
            }]
        }]
    }

    # 3. Set the mock response as the return value of describe_instances
    mock_ec2.describe_instances.return_value = mock_response

    # 4. Call your application function (which will now use the mock)
    status = get_instance_status('i-1234567890abcdef0')

    # 5. Assert that your application behaves correctly
    assert status == 'pending'

    # Example with multiple instances
    mock_response_multiple = {
        'Reservations': [{
            'Instances': [
                {'InstanceId': 'i-1', 'State': {'Name': 'pending'}}
            ]
        }]
    }
    mock_ec2.describe_instances.return_value = mock_response_multiple
    # ... your test logic to handle multiple instances
