Step-by-Step Solution
Solution:
Step 1: Understand parallel testing on Selenium Grid
To test multiple browsers simultaneously, create separate Remote WebDriver instances with specific capabilities for each browser.Step 2: Evaluate options for correctness
Create two Remote WebDriver instances with different desired_capabilities and run tests in parallel threads correctly describes creating two instances and running them in parallel threads. Use webdriver.Chrome() and webdriver.Firefox() locally without Remote runs locally, not on Grid. Set desired_capabilities to {'browserName': 'chrome,firefox'} in one Remote call incorrectly tries to combine browsers in one call. Run tests sequentially on one Remote WebDriver instance switching browsers runs sequentially, not simultaneously.Final Answer:
Create two Remote WebDriver instances with different desired_capabilities and run tests in parallel threads -> Option CQuick Check:
Parallel tests need separate Remote drivers per browser [OK]
Quick Trick: Use separate Remote drivers and threads for parallel browsers [OK]
Common Mistakes:
- Trying to specify multiple browsers in one desired_capabilities dict
- Running tests locally instead of on Grid
- Running tests sequentially instead of parallel
