Selenium Java - TestNG Integration

Given this TestNG XML snippet, how many tests will run in parallel?

<suite name="Suite" parallel="tests" thread-count="3">
  <test name="Test1"></test>
  <test name="Test2"></test>
  <test name="Test3"></test>
  <test name="Test4"></test>
</suite>

AAll 4 tests run in parallel

B3 tests run in parallel, 1 waits

COnly 1 test runs at a time

D2 tests run in parallel, 2 wait

Step-by-Step Solution

Solution:

Step 1: Understand thread-count and parallel attribute
parallel="tests" means tests run in parallel. thread-count="3" limits max parallel threads to 3.
Step 2: Apply thread-count to number of tests
There are 4 tests but only 3 threads, so 3 tests run simultaneously and 1 waits.
Final Answer:
3 tests run in parallel, 1 waits -> Option B
Quick Check:
thread-count limits parallel tests to 3 [OK]

Quick Trick: thread-count limits max parallel tests running [OK]

Common Mistakes:

Assuming all tests run parallel ignoring thread-count
Confusing parallel="tests" with parallel="methods"
Ignoring that thread-count caps parallelism
