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.""";
