Display image filename/filepath in exceptions

[sergiu-mezei-aera]

Hi guys,

We're using shutterbug to do multiple image comparisons inside a test method and we're using Allure reports for the reporting part. I would like to suggest an improvement: displaying the image filename/filepath inside the exceptions thrown rather than just the "image1"/"image2" hardcoded strings or at least any image path information (like the resulting diff image path). This would help us to easily debug and fix tests because we know which images are affected.

For example: We get an exception like this: Images dimensions mismatch: image1 - 300x753; image2 - 300x754 com.assertthat.selenium_shutterbug.utils.image.UnableToCompareImagesException: Images dimensions mismatch: image1 - 300x753; image2 - 300x754 at com.assertthat.selenium_shutterbug.utils.image.ImageProcessor.imagesAreEqualsWithDiff(ImageProcessor.java:140) at com.assertthat.selenium_shutterbug.core.Snapshot.equalsWithDiff(Snapshot.java:325) at utils.ImageCompare.compareWebElement(ImageCompare.java:133) at ui_tests.ui_builder_tests.TableComponentTest6.goToNextNodeRowSelectionTrueTest(TableComponentTest6.java:102) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

Thanks in advance!

Hi @sergiu-mezei-aera ,

Could you please share the snippet of code which you use to do the comparison? Do you read both images from the disk first?

Hi @glibas,

I read the expected image (BufferedImage) from the disk and the image we compare with is a UI capture (snapshot).

saveSnapshot(actual, imageName + "-actual", actualScreenShotFolder);

boolean result = actual.equalsWithDiff(expected, diffFolder + imageName, deviation);

The exception comes from the equalsWithDiff() method, but we need more info of the image1/2 names to be clearer for debugging.
