Do Google Analytics or Comscore Tags Cause Issues in Testing ? Selenium Interview Questions

Описание: Yes, Google Analytics (GA) and Comscore tags can cause issues in testing, but not always. It depends on the test environment, network setup, and test goals.
1. Slow Test Execution
Tags make external calls (e.g., google-analytics.com, scorecardresearch.com)
On slow or blocked networks, these calls can delay page load or cause timeouts
2. Flaky Selenium Tests
GA or Comscore tags might delay rendering of interactive elements
If tests use waitForPageToLoad or document.readyState, these tags may affect when the DOM is considered "ready"
