Are you ready to supercharge your QA and automation testing workflow?

How to use it:

  1. Open the Elements tab.
  2. Right-click on the desired element.
  3. Select "Capture Node Screenshot."

?? QA Example: Use this feature to capture screenshots of a specific error message or a misaligned UI component and attach it to your bug report for better clarity.

2?? Simulate Network Throttling

Testing performance on different network speeds is crucial for delivering a seamless user experience. DevTools allows you to emulate slow network conditions without external tools.

How to use it:

  1. Navigate to the Network tab.
  2. Open the dropdown labelled "Online" and choose a predefined condition like "Slow 3G."
  3. Alternatively, create a custom profile by selecting "Add..."

?? QA Example: Validate that a video player gracefully switches to a lower resolution or pauses buffering on slow networks.
