pyqt5不显示设计好的界面

Question

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.horizontalLayoutWidget = QtWidgets.QWidget(self.centralwidget)
        self.horizontalLayoutWidget.setGeometry(QtCore.QRect(70, 50, 451, 181))
        self.horizontalLayoutWidget.setObjectName("horizontalLayoutWidget")
        self.horizontalLayout = QtWidgets.QHBoxLayout(self.horizontalLayoutWidget)
        self.horizontalLayout.setContentsMargins(0, 0, 0, 0)
        self.horizontalLayout.setObjectName("horizontalLayout")
        self.listView = QtWidgets.QListView(self.horizontalLayoutWidget)
        self.listView.setObjectName("listView")
        self.horizontalLayout.addWidget(self.listView)
        self.pushButton = QtWidgets.QPushButton(self.horizontalLayoutWidget)
        self.pushButton.setObjectName("pushButton")
        self.horizontalLayout.addWidget(self.pushButton)
        self.horizontalLayoutWidget_2 = QtWidgets.QWidget(self.centralwidget)
        self.horizontalLayoutWidget_2.setGeometry(QtCore.QRect(70, 270, 451, 80))
        self.horizontalLayoutWidget_2.setObjectName("horizontalLayoutWidget_2")
        self.horizontalLayout_2 = QtWidgets.QHBoxLayout(self.horizontalLayoutWidget_2)
        self.horizontalLayout_2.setContentsMargins(0, 0, 0, 0)
        self.horizontalLayout_2.setObjectName("horizontalLayout_2")
        self.pushButton_2 = QtWidgets.QPushButton(self.horizontalLayoutWidget_2)
        self.pushButton_2.setObjectName("pushButton_2")
        self.horizontalLayout_2.addWidget(self.pushButton_2)
        self.radioButton = QtWidgets.QRadioButton(self.horizontalLayoutWidget_2)
        self.radioButton.setObjectName("radioButton")
        self.horizontalLayout_2.addWidget(self.radioButton)
        self.checkBox = QtWidgets.QCheckBox(self.horizontalLayoutWidget_2)
        self.checkBox.setObjectName("checkBox")
        self.horizontalLayout_2.addWidget(self.checkBox)
        self.verticalLayoutWidget = QtWidgets.QWidget(self.centralwidget)
        self.verticalLayoutWidget.setGeometry(QtCore.QRect(70, 390, 451, 80))
        self.verticalLayoutWidget.setObjectName("verticalLayoutWidget")
        self.verticalLayout = QtWidgets.QVBoxLayout(self.verticalLayoutWidget)
        self.verticalLayout.setContentsMargins(0, 0, 0, 0)
        self.verticalLayout.setObjectName("verticalLayout")
        self.horizontalSlider = QtWidgets.QSlider(self.verticalLayoutWidget)
        self.horizontalSlider.setOrientation(QtCore.Qt.Horizontal)
        self.horizontalSlider.setObjectName("horizontalSlider")
        self.verticalLayout.addWidget(self.horizontalSlider)
        self.buttonBox = QtWidgets.QDialogButtonBox(self.verticalLayoutWidget)
        self.buttonBox.setStandardButtons(QtWidgets.QDialogButtonBox.Cancel|QtWidgets.QDialogButtonBox.Ok)
        self.buttonBox.setObjectName("buttonBox")
        self.verticalLayout.addWidget(self.buttonBox)
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 23))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.pushButton.setText(_translate("MainWindow", "PushButton"))
        self.pushButton_2.setText(_translate("MainWindow", "PushButton"))
        self.radioButton.setText(_translate("MainWindow", "RadioButton"))
        self.checkBox.setText(_translate("MainWindow", "CheckBox"))

import sys
import test
from PyQt5.QtWidgets import QApplication, QMainWindow

if __name__ == '__name__':
    app = QApplication(sys.argv)
    mainWindow = QMainWindow()
    ui = test.Ui_MainWindow()
    ui.setupUi(mainWindow)
    mainWindow.show()
    sys.exit(app.exec_())

两段代码在同一路径下，运行第二段代码，不报错，但是不显示pyDesigner里设计好的窗口，就直接显示Process finished with exit code 0，就没了，请问怎么能看到窗口？（已经试过不是解释器的问题，其他代码可以正常显示图窗等页面）
