|
|
In the window called "Text After XOR Test" there should be two
|
|
composite components, at the bottom of each component the green text
|
|
"Test passes if this is green!" should be visible.
|
|
|
|
On the top component this text should be green on all platforms.
|
|
On the bottom component it is possible that on non-Windows
|
|
platforms text can be of other color or not visible at all.
|
|
That does not constitute a problem.
|
|
|
|
So if platform is Windows and green text appears twice or on any
|
|
other platform green text appears at least once press "Pass",
|
|
otherwise press "Fail".
