The text pane contains the phrase "the quick brown fox jumps over the lazy dog",
|
|
all the words are separated by tabs. When the test starts, the whole phrase should
|
|
appear on one line. If it is wrapped along two or more lines, the test FAILS.
|
|
|
|
Otherwise, place the text caret in the very end of the line (e.g. by clicking
|
|
in the line and hitting End). Press Enter twice. The text should appear as one
|
|
line at all times. If the text wraps when you press Enter, the test FAILS.
