Selenium Python - CI/CD Integration

Given the code snippet below, what will be the output?

from concurrent.futures import ThreadPoolExecutor
import time

def test_func(name):
    time.sleep(1)
    return f"Test {name} done"

with ThreadPoolExecutor(max_workers=3) as executor:
    results = list(executor.map(test_func, ['A', 'B', 'C', 'D']))
print(results)

AError due to max_workers less than tasks

B['Test A done', 'Test B done', 'Test C done']

C['Test A done', 'Test B done', 'Test C done', 'Test D done']

D['Test D done']

Step-by-Step Solution

Solution:

Step 1: Understand ThreadPoolExecutor with max_workers=3
It runs up to 3 threads at once, but can handle more tasks by queuing them.
Step 2: Analyze executor.map behavior
executor.map runs test_func on all 4 inputs and returns results in order after all finish.
Final Answer:
['Test A done', 'Test B done', 'Test C done', 'Test D done'] -> Option C
Quick Check:
All tasks run, results list includes all [OK]

Quick Trick: ThreadPoolExecutor queues extra tasks beyond max_workers [OK]

Common Mistakes:

Assuming only 3 results because max_workers=3
Expecting error due to more tasks than workers
Thinking results order changes
