+### Skip Failure
+You can avoid the test fails for a given threshold but yet generates the difference image.
+Just declare an object and pass it in options as `skipFailure`:
+```
+I.seeVisualDiff("image.png", {prepareBaseImage: true, tolerance: 1, skipFailure: true});
+```
+After this, the system generates the difference image but does not fail the test.
+This works for `seeVisualDiff` and `seeVisualDiffForElement`.
