我正在为PyQt具有pytest-qt. 我想创建打开图形窗口，做一些测试然后关闭窗口，而不是为每个测试打开一个新窗口，即。对窗口本身使用模块夹具。我通过调用本地函数 aQtBot而不是使用默认夹具，并删除了嘲笑者，成功地完成了这部分工作。所以我非常接近我的目标。
但是，但我无法关闭窗口（并测试QMessageBox关闭事件）。
我举了一些例子，比如
如何处理模态对话框及其git讨论，或者qmessage问题；这似乎接近我的问题。建议使用计时器等待QMessageBox出现然后单击按钮选项，但显然我无法正确应用它们。在我的尝试中，pytest获得关闭需求，而不是点击dialog框。所以，我必须点击自己才能完成测试。
这是一个小例子，带有文件GUI.py：
#!/usr/bin/python3
# -*- coding: utf-8 -*-
import sys
from PyQt5 import QtGui, QtCore, QtWidgets
from PyQt5.QtWidgets import *
from PyQt5.QtCore import QCoreApplication, Qt, QObject
from PyQt5.QtGui import QIcon
class Example(QMainWindow):
def __init__(self, parent = None):
super().__init__()
self.initUI(self)
def initUI(self, MainWindow):
# centralwidget
MainWindow.resize(346, 193)
self.centralwidget = QtWidgets.QWidget(MainWindow)
# The Action to quit
self.toolb_action_Exit = QAction(QIcon('exit.png'), 'Exit', self)
self.toolb_action_Exit.setShortcut('Ctrl+Q')
self.toolb_action_Exit.triggered.connect(self.close)
# The Button
self.btn_prt = QtWidgets.QPushButton(self.centralwidget)
self.btn_prt.setGeometry(QtCore.QRect(120, 20, 89, 25))
self.btn_prt.clicked.connect(lambda: self.doPrint() )
self.btn_quit = QtWidgets.QPushButton(self.centralwidget)
self.btn_quit.setGeometry(QtCore.QRect(220, 20, 89, 25))
self.btn_quit.clicked.connect(lambda: self.close() )
# The textEdit
self.textEdit = QtWidgets.QTextEdit(self.centralwidget)
self.textEdit.setGeometry(QtCore.QRect(10, 60, 321, 81))
# Show the frame
MainWindow.setCentralWidget(self.centralwidget)
self.show()
def doPrint(self):
print('TEST doPrint')
def closeEvent(self, event):
# Ask a question before to quit.
self.replyClosing = QMessageBox.question(self, 'Message',
"Are you sure to quit?", QMessageBox.Yes |
QMessageBox.No, QMessageBox.No)
if self.replyClosing == QMessageBox.Yes:
event.accept()
else:
event.ignore()
def main_GUI():
app = QApplication(sys.argv)
imageViewer = Example()
return app, imageViewer
if __name__ == '__main__':
app, imageViewer =main_GUI()
rc= app.exec_()
print('App end is exit code {}'.format(rc))
sys.exit(rc)
和pytest名为的文件test_GUI.py：
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import os, sys
import pytest
from PyQt5 import QtGui, QtCore, QtWidgets, QtTest
from PyQt5.QtWidgets import *
from PyQt5.QtCore import QCoreApplication, Qt, QObject
from pytestqt.plugin import QtBot
GUI = __import__('GUI')
@pytest.yield_fixture(scope="module")
def qtbot_session(qapp, request):
print(" SETUP qtbot")
result = QtBot(qapp)
with capture_exceptions() as exceptions:
yield result
print(" TEARDOWN qtbot")
@pytest.fixture(scope="module")
def Viewer(request):
print(" SETUP GUI")
app, imageViewer = GUI.main_GUI()
qtbotbis = QtBot(app)
# qtbotbis.addWidget(imageViewer)
# qtbotbis.wait_for_window_shown(imageViewer)
QtTest.QTest.qWait(0.5 *1000)
yield app, imageViewer, qtbotbis
# EXIT
# mocker.patch.object(QMessageBox, 'question', return_value=QMessageBox.Yes)
# imageViewer.toolb_action_Exit.trigger()
def handle_dialog():
# while not imageViewer.replyClosing.isVisible():
# app.processEvents()
box = QMessageBox()
box.setStandardButtons(QMessageBox.Yes)
button = box.button(QMessageBox.Yes)
qtbotbis.mouseClick(button, QtCore.Qt.LeftButton)
QtCore.QTimer.singleShot(100, handle_dialog)
qtbotbis.mouseClick(imageViewer.btn_quit, QtCore.Qt.LeftButton, delay=1)
assert imageViewer.close()
print(" TEARDOWN GUI")
class Test_GUI() :
def test_interface(self, Viewer):
print(" beginning ")
app, imageViewer, qtbot = Viewer
qtbot.mouseClick( imageViewer.btn_prt, QtCore.Qt.LeftButton )
QtTest.QTest.qWait(0.5 *1000)
assert True
print(" Test passed")
知道我缺少什么吗？任何其他想法或建议也将不胜感激。
