Raise a custom exception with visual diff assertion failures #1577
Description
Raise a custom exception with visual diff assertion failures
For visual testing, instead of raising a general Exception when a visual difference failure is detected, SeleniumBase should raise a custom VisualException to differentiate that failure apart from others. The failure output of the completed update should look something like this:
E seleniumbase.common.exceptions.VisualException:
E AssertionError:
E First differing element 39:
E ['div', [['class', ['section', 'hidden-section', 'image-section']]]]
E ['div', [['class', ['section', 'image-section']]]]
E
E - ['div', [['class', ['section', 'hidden-section', 'image-section']]]],
E ? ------------------
E + ['div', [['class', ['section', 'image-section']]]],
E *
E *** Exception: <Level 3> Visual Diff Failure:
E * HTML tag attribute values don't match the baseline!
