You want to test a form that requires a CSRF token. Which approach correctly handles this in Flask testing?
AUse GET requests instead of POST to avoid CSRF checks
BManually add a fake CSRF token in the form data without disabling protection
CDisable CSRF protection in the test config before posting form data
DIgnore CSRF tokens as they are not checked during testing
Step-by-Step Solution
Solution:

  1. Step 1: Understand CSRF protection in Flask forms

    CSRF tokens prevent unauthorized form submissions. During testing, you can disable CSRF to simplify tests.

  2. Step 2: Evaluate options for handling CSRF in tests

    Disabling CSRF in test config is the correct way. Adding fake tokens or ignoring tokens won't work reliably. GET requests do not submit forms.

  3. Final Answer:

    Disable CSRF protection in the test config before posting form data -> Option C

  4. Quick Check:

    Disable CSRF in tests to avoid token errors [OK]
Quick Trick: Turn off CSRF in tests to simplify form POSTs [OK]
Common Mistakes:
MISTAKES
  • Trying to fake CSRF tokens manually
