medium📝 Predict Output Q4 of 15

Selenium Python - Selenium Grid

ABoth tests run in parallel on the same node

BOne test runs; the other waits until the node is free

CBoth tests fail because only one node supports Chrome

DTests run on different nodes regardless of browser support

Step-by-Step Solution

Solution:

Step 1: Understand node browser support and test allocation
Only one node supports Chrome, so it can run one test at a time per browser instance.
Step 2: Analyze simultaneous test requests
The first test runs immediately; the second waits until the node is free.
Final Answer:
One test runs; the other waits until the node is free -> Option B
Quick Check:
Single node, multiple tests = queued execution [OK]

Quick Trick: One node runs one browser test at a time [OK]

Common Mistakes:

Assuming parallel runs on single node for same browser
Thinking tests fail automatically
Ignoring browser support on nodes
