You want to organize a large number of tests into suites that share setup and teardown steps. Which approach best supports this in Python unittest?
AWrite all tests in one TestCase class without setup methods
BUse print statements to separate tests visually
CCreate multiple TestCase classes with setUp and tearDown methods, then group their instances in TestSuites
DRun each test individually without grouping
Step-by-Step Solution
Solution:

  1. Step 1: Understand setup/teardown in unittest

    setUp and tearDown methods in TestCase classes run before and after each test, helping prepare and clean up.

  2. Step 2: Organize tests for sharing setup

    Grouping related TestCase instances in TestSuites allows running tests that share setup/teardown logically.

  3. Final Answer:

    Create multiple TestCase classes with setUp and tearDown methods, then group their instances in TestSuites -> Option C

  4. Quick Check:

    Use TestCase setup + TestSuite grouping = B [OK]
Quick Trick: Use TestCase setup with TestSuite grouping for shared steps [OK]
Common Mistakes:
MISTAKES
  • Putting all tests in one class without setup
  • Using print instead of setup methods
  • Running tests one by one without suites
