In a CI pipeline, why is it advantageous to execute Selenium tests concurrently rather than sequentially?
ATo reduce total test execution time and provide faster feedback
BTo increase the number of test failures reported
CTo avoid using multiple browser instances
DTo simplify test script maintenance
Step-by-Step Solution
Solution:
  1. Step 1: Understand test execution time

    Sequential execution runs tests one after another, increasing total time.
  2. Step 2: Benefit of parallel execution

    Running tests concurrently reduces overall time, speeding up feedback in CI.
  3. Final Answer:

    To reduce total test execution time and provide faster feedback -> Option A
  4. Quick Check:

    Faster feedback is key in CI [OK]
Quick Trick: Parallel tests cut down runtime significantly [OK]
Common Mistakes:
  • Thinking parallel execution increases failures
  • Assuming parallel tests use fewer browser instances
  • Believing parallel execution simplifies maintenance
