Image Comparison in the Playback Log

Last modified on September 06, 2021


LoadNinja takes screenshots of your tested application’s pages when certain events occur during script recording and playback. You can then compare the images if, for example, your test failed and you want to see whether the UI of your application has changed since you recorded the script.

Compare images

To compare images:

  1. Click Playback Log at the bottom of the recorder screen:

    Open the playback log

    Click the image to enlarge it.

  2. Click an image icon in the Image column:

    Click an image icon

    Click the image to enlarge it.

  3. In the resulting window, you can view the images captured during script recording and playback, and check for differences on the Comparison tab:

    Compare images

    Click the image to enlarge it.

    Note: The date and time the image was captured are below the image.
