You want to organize tests for a large project with multiple features and shared utilities. Which structure best supports scaling?
A<pre>tests/ feature1_test.py feature2_test.py helpers_test.py</pre>
B<pre>tests/ test_all.py test_helpers.py</pre>
C<pre>tests/ feature1/ test_api.py feature2/ test_ui.py utils/ test_helpers.py</pre>
D<pre>tests/ api_tests.py ui_tests.py helpers.py</pre>
Step-by-Step Solution
Solution:
  1. Step 1: Analyze folder structure for clarity

    tests/
      feature1/
        test_api.py
      feature2/
        test_ui.py
      utils/
        test_helpers.py
    separates features and utilities into folders, aiding organization.
  2. Step 2: Compare other options

    Other options mix tests or lack clear separation, making scaling harder.
  3. Final Answer:

    tests/
      feature1/
        test_api.py
      feature2/
        test_ui.py
      utils/
        test_helpers.py
    -> Option C
