Question #280712 on Sikuli changed:
https://answers.launchpad.net/sikuli/+question/280712

Description changed to:
Sikuli doesn't find the exact Image match on the screen (i.e) Test
passes even if some part of the text Image changes.

For example,

Expected Image(captured Image for validation)
----------------------

Img3=>XYZOne


I performed three different test by passing different input values to the text field in the screen as shown below

Test 1 :field with the text as =>    XYZOne
Test 2 :field with the text as=>     XYZOn
Test 3 :field with the text as=>     XYXOne

My script is for Image validation:
------------------------------------------------

 try {
			 Thread.sleep(2);

                        Match image=s.find("Img3.png");
			System.out.println("Image matched");
		} catch (Exception e) {

                        System.out.println ("Image not matched");

			e.printStackTrace();
		}


Test Output:
------------------

Test 1:
---------
Test passes as it find the right image on the screen.

Test 2:
---------
Actual text on the screen differs from the expected one on the Img3 but test passes.
Actual one is => XYZOn  
Expected Image => XYZOne
(i.e) 'e' missing in the actual text on the screen.

In this test a portion of the text matched hence the test passes which
is not the expected behaviour. The test should fail even if there is
minor change either at the begging or at the end or at the middle of the
text(anywhere)

Test 3:
----------
This test fails as it doesn't find the some part of the test is not matched(may be the first portion of the text). But the same test passes when I used 'exists' command instead of 'find' command in the script.


Therefore there is no reliability with sikuli when it comes to Image
comparison. Tool is not finding the exact match(i.e)  test should fail
even if a single character changes from the expected Image. This behaves
very badly when it comes to date field image validation(i.e) test keeps
passing even if more than one number changes in the dates.

Could someone advice me on this as how to check the exact Image match
with sikuli or Is there is any better way to find the exact Image match.

We need to sort this urgently.

Quick help is appreciated.
