Image found failed after moving Junit test case to another same PC

Asked by jerry

I wrote a JUnit test case using sikulixapi.jar(get from sikulixsetup 1.1), however, when I let the case running on another same windows 7 client all the images cannot be found.

Below is the log:

The two windows clients has the same monitor and the same resolution ratio.

Dose anyone else has encountered the issue?
Any help is appreciated.

Thx.

but there must be differences on the pixel level, that one might not realise when looking at the monitor:
anti-aliasing, shadows, theme differences, ....

compare an image and a shot on the other machine in an image viewer with some magnification, so you can see the pixels.

Thanks RaiMan!

I compared the image and the shot, there are some pixels differences.

Is there any way I can do to resolve this issue or else I have to re-capture all the images ---- a lot of work :-(

Sorry, but currently no other way, than to make another set of images.

This problem will only be addressed later this year with version 2.

Try to understand why your images are different. Maybe there are some settings that you can change that will make the required difference. For example:

Clear type
Smooth Edges

Clear type setting will change text appearance.
To disable/enable clear type, go to Control Panel -> Display ->Adjust ClearType text.

Smooth edges of screen fonts option must be disabled.
The option can be found at Control Panel -> System -> Advanced System Settings -> Settings (under Performance). Uncheck the “Smooth edges of screen fonts” option.

Thanks Eugene for the detailed instruction.

I guess "Clear type" must be enabled, right?

Will have a try now.

It might be enabled or disabled. What's important is that it will be the same on both systems!
What kind of differences in your images are you experiencing?
Can you provide a pair of patterns that look different?

Can you help with this problem?

Provide an answer of your own, or ask jerry for more information if necessary.
