Python Screen.cursor_back Examples

Example #1

def test_cursor_back():
    screen = Screen(10, 10)

    # Moving the cursor left at the margin doesn't do anything
    screen.cursor.x = 0
    screen.cursor_back(1)
    assert screen.cursor.x == 0

    screen.cursor.x = 3

    # Moving the cursor past the left margin moves it to the left margin
    screen.cursor_back(10)
    assert screen.cursor.x == 0

    screen.cursor.x = 5
    # Can move the cursor more than one back.
    screen.cursor_back(3)
    assert screen.cursor.x == 2
