Which Python syntax correctly starts parallel execution of Selenium tests using pytest-xdist?
Apytest -p 4
Bpytest --parallel=4
Cpytest -n 4
Dpytest --threads=4
Step-by-Step Solution
Solution:
  1. Step 1: Recall pytest-xdist command for parallel tests

    The correct flag to run tests in parallel with pytest-xdist is '-n' followed by number of workers.
  2. Step 2: Check other options for correctness

    Options with '--parallel', '-p', or '--threads' are incorrect for pytest-xdist.
  3. Final Answer:

    pytest -n 4 -> Option C
  4. Quick Check:

    pytest-xdist parallel flag = -n [OK]
Quick Trick: Use 'pytest -n ' to run tests in parallel [OK]
Common Mistakes:
  • Using incorrect flags like --parallel or --threads
  • Confusing '-p' with parallel execution
  • Not installing pytest-xdist before using -n
