AThe test will fail with an error about missing task
BThe test will pass silently
CThe task will run with default behavior
DThe test will retry the task automatically

  1. Step 1: Understand task lookup

    Cypress looks for the task name in the configuration file. If not found, it cannot execute it.

  2. Step 2: Result of missing task

    Calling a non-existent task causes Cypress to throw an error and fail the test.

  3. Final Answer:

    The test will fail with an error about missing task -> Option A

  4. Quick Check:

    Missing task call = test failure [OK]
Quick Trick: Always define tasks before calling them to avoid errors [OK]
Common Mistakes:
  • Assuming tasks run without definition
  • Expecting silent pass on missing tasks
  • Thinking Cypress retries missing tasks
