Thanks for posting about this TDante.

In certain applications, test cases are created where it is important to check if the image that is delivered by the server and rendered on a page is the image that should be available in a web page.

This can be done using eValid's "CompareImages" command.

eValid can save an image locally as a baseline image file from a webpage and then compare it with the retrieved image (the response image file).

The response image is saved locally using the "Save Selected Image" command.

To compare images in this way, follow the simple step outline below:

(1) Start recording.

(2) Navigate to the desired website starting page.

(3) Select the image you want to compare and save a copy locally.

This can be done by highlighting the image, and then using the "Save Selected Image" command and using a filename that indicates you are using this file as your response image.

(4) Stop recording.

(5) Copy the saved image as your baseline image file.

(5) Edit the script and insert the "CompareImages" command after the "Save Selected Image" command with the filenames of the two images as the arguments to the "CompareImages" command.

On playback, eValid will save a copy of the selected image and execute the CompareImages command.

This command will compare the response image to the baseline image.

An error message is reported in the event log if the two images are unequal.
