我正在尝试在pytest
上运行PyCharm project
次测试。测试代码如下:
def test_window_created(self, create_xld_main_window):
"""This test tests, whether or not the Gtk.Window has been created.
"""
screen = Wnck.Screen.get_default()
screen.force_update() # recommended per Wnck documentation
window_list = screen.get_windows()
for window in window_list:
print(window.get_name())
if window.has_name():
if window.get_name() == self.xld_main_window.get_title():
window_found = True
break
assert window_found, 'The Gtk.Window named {window_name} has not been found.'\
.format(window_name=self.xld_main_window.get_title())
# clean up Wnck (saves resources, check documentation)
del window
del screen
Wnck.shutdown()
上述夹具如下所示:
@pytest.fixture()
def create_xld_main_window(self):
AppSettings.load_settings()
VocableManager.load_vocables()
self.xld_main_window = XLDMainWindow()
self.xld_main_window.show_all()
GTKGUITestHelper.refresh_gui()
refresh_gui
方法如下:
@classmethod
def refresh_gui(cls, delay=0):
# print('delay', delay)
while Gtk.events_pending():
Gtk.main_iteration_do(blocking=False)
time.sleep(float(delay))
当我按如下方式运行此测试时:
~/development/pycharm-workspace/gtkplus-tool/gtkplustool$ PYTHONPATH=~/development/pycharm-workspace/gtkplus-tool/ python -m pytest -v ~/development/pycharm-workspace/gtkplus-tool/test/
(我将项目根目录添加到python路径,以模拟在PyCharm中使用测试运行器时存在的相同条件。我读到PyCharm总是将项目根添加到python路径。)
...我的测试得到以下输出:
================================================= test session starts ==================================================
platform linux -- Python 3.4.3 -- py-1.4.30 -- pytest-2.7.2 -- /home/xiaolong/development/anaconda3/envs/gtkplus-tool/bin/python

../test/gui/test_XLDMainWindow.py::TestXLDMainWindow::test_window_created Segmentation fault (core dumped)
这种分段错误的原因是什么?
当我使用PyCharm测试运行器运行此测试时,我得到以下结果:
Test: test_XLDMainWindow.py Time elapsed: <TERMINATED>
更重要的是,由于该分段错误,pytest停止运行任何进一步的测试,因此我无法以舒适的方式运行其他测试。
答案 0 :(得分:0)
我现在已经弄明白了,但我对seg故障的原因很不满意。
我评论了这一行:
Wnck.shutdown()
seg故障消失了。但是,我现在不确定,如果有任何泄漏或其他什么,当我没有正确关闭Wnck时。此外,此关闭之前已经有效。我几天前运行的代码相同。也许一些Ubuntu更新破坏了Wnck或其他东西。
欢迎任何进一步解答导致seg故障的原因。
