+
+This test emulates situation when xhr.upload object is not present, so upload progress cannot be monitored.
+
+ * Drop an image.
+ * Check if `upload widget` is displayed.
+ * Upload progress will not be reported - it will jump from 0% to upload success.
+ * Check if upload is complete and test image is visible.
+
+**Note:** This test use upload mock which will show you *Lena* instead of the real uploaded image.
