This test has two steps:
1. you need to place some text onto the system clipboard,
for example,
on Windows, you could highlight some text in notepad, and do a Ctrl-C
or select menu Edit->Copy;
on Linux or Mac, you can do the same with any Terminal or Console or
Text application.
2. After you copy to system clipboard, press "Click Me" button.
Test will fail if any exception is thrown.
Press Pass if you see "Test Passed" in log area.""";
