我想在我的项目中测试一个模块，但我遇到了一些问题。我不知道如何在单击按钮后检查窗口的正确打开。

我有 Windows SelectAddingBookTypeWindow 和 AddSchoolBookWindow。我想检查在单击名为 selectBtn 的按钮后是否会打开 AddSchoolBookWindow。

我当前的测试（我对最后一个字符串有问题，因为我不知道我必须使用哪种方法）：

@pytest.fixture
def open_window(qtbot):
    def _press_button(window):
        widget = window()
        qtbot.addWidget(widget)
        widget.show()
        qtbot.wait_for_window_shown(widget)
        sleep(3)
        return widget
    return _press_button


class TestSelectAddingBookTypeWindow:
    def test_select_schoolbook(self, open_window, qtbot):
        widget = open_window(SelectAddingBookTypeWindow)
        qtbot.mouseClick(widget.schoolbookSelector, QtCore.Qt.LeftButton)
        qtbot.mouseClick(widget.selectBtn, QtCore.Qt.LeftButton)
        assert widget.close()
        assert AddSchoolBookWindow.isActiveWindow()

我的课程： A. SelectAddingBookTypeWindow

class SelectBookTypeWindow(QDialog, Ui_selectBookTypeWindow):
    @logger.catch
    def __init__(self, widget1, widget2):
        super().__init__()
        self.setupUi(self)
        self.selectBtn.clicked.connect(lambda x: self.open_new_window(widget1, widget2))

    @logger.catch
    def open_new_window(self, schoolbook_widget, fictionbook_widget):
        if self.schoolbookSelector.isChecked():
            widget = schoolbook_widget()
        elif self.fictionbookSelector.isChecked():
            widget = fictionbook_widget()
        widget.show()
        self.close()


class SelectAddingBookTypeWindow(SelectBookTypeWindow):
    @logger.catch
    def __init__(self):
        super().__init__(AddSchoolBookWindow, AddFictionBookWindow)

B. AddSchoolBookWindow

class AddSchoolBookWindow(QDialog, Ui_AddSchoolbookWindow):
    @logger.catch
    def __init__(self):
        super().__init__()
        self.setupUi(self)
        self.widgets = [
            self.schoolbookAuthor, self.schoolbookTitle, self.schoolbookPublishHouse,
            self.schoolbookPublishYear, self.schoolbookInvoiceNum, self.schoolbookInvoiceDate, self.schoolbookClass,
            self.schoolbookCount, self.schoolbookPrice
        ]
        self.schoolbookSaveBtn.clicked.connect(lambda _: self.save_book())
        self.schoolbookClearBtn.clicked.connect(lambda _: Utils.clear_fields(self.widgets, self.schoolbookInvoiceDate))
        self.schoolbookCancelBtn.clicked.connect(lambda _: self.close())

    @logger.catch
    def save_book(self):
        field_names = Config.COLUMNS['SchoolBook']
        user_data = list(map(lambda x: x.text(), self.widgets))
        book_sum = Utils.calculate_book_sum(user_data)
        user_data.append(str(book_sum))
        book = dict(zip(field_names[1:], user_data))
        db = DatabaseManager(Config.PATHES['TO_DATABASE']['PROD'])
        model = Schoolbook('SchoolBook', db.connection)
        model.insert_book(book)
        logger.success(f'The {book} success add in the database')
        model.model.select()

这是完整代码的一小部分，但完整代码并不能解决这个问题。

您的问题是小部件不可访问，因为它是一个局部变量，我也怀疑窗口是否会显示，因为它应该稍后被删除，所以要访问它，我将创建一个属性：

class SelectBookTypeWindow(QtWidgets.QDialog, Ui_selectBookTypeWindow):
    def __init__(self, widget1, widget2):
        super().__init__()
        self.setupUi(self)
        self.selectBtn.clicked.connect(lambda x: self.open_new_window(widget1, widget2))

        self._selected_window = None

    @property
    def selected_window(self):
        return self._selected_window

    def open_new_window(self, schoolbook_widget, fictionbook_widget):
        if self.schoolbookSelector.isChecked():
            self._selected_window = schoolbook_widget()
        elif self.fictionbookSelector.isChecked():
            self._selected_window = fictionbook_widget()
        if self.selected_window is not None:
            self.selected_window.show()
            self.close()

然后在测试中你应该验证 selected_window 不是 None 并且它的基类是 AddSchoolBookWindow，也避免使用 time.sleep()，在测试的情况下使用QTest.qWait()

import pytest
from PyQt5 import QtCore, QtTest

from your_package import AddSchoolBookWindow, SelectAddingBookTypeWindow


@pytest.fixture
def open_window(qtbot):
    def callback(window):
        widget = window()
        qtbot.addWidget(widget)
        widget.show()
        qtbot.wait_for_window_shown(widget)
        QtTest.QTest.qWait(3 * 1000)
        return widget

    return callback


class TestSelectAddingBookTypeWindow:
    def test_select_schoolbook(self, open_window, qtbot):
        widget = open_window(SelectAddingBookTypeWindow)
        assert widget.isVisible()
        qtbot.mouseClick(widget.schoolbookSelector, QtCore.Qt.LeftButton)
        qtbot.mouseClick(widget.selectBtn, QtCore.Qt.LeftButton)
        assert widget.isHidden()
        assert widget.selected_window is not None
        assert isinstance(widget.selected_window, AddSchoolBookWindow)
        assert widget.selected_window.isVisible()
