为pyqt

Question

我已经搜索了很多关于这个但没有找到任何东西......

我有一个自定义异常类，它调用了一个QDialog来显示警告消息。现在我正在为我的应用程序编写测试，在测试中，我发送的数据将使应用程序引发该异常并因此对话会出现。

但是当我使用pt.test运行测试时，对话框出现了，当我关闭它时，它会打印在我的控制台上。

E           Failed: DID NOT RAISE
apptest.py:31: Failed
----------------------------- Captured stderr call -----------------------------
Traceback (most recent call last):

  File "/home/kapil/mp3wav/mp3wav/application.py", line 105, in checkFile
    raise FileTypeException(fileType, self)
mp3wav.exceptions.fileexception.FileTypeException

这是我的测试文件..

import pytest
import os
from PyQt4.QtGui import *
from PyQt4.QtCore import *
from mp3wav.application import Mp3WavApp
from mp3wav.exceptions.fileexception import FileTypeException
from mp3wav.exceptions.libraryexception import LibraryException
from mp3wav.exceptions.filenotexistexception import FileNotExistException
from mp3wav.exceptions.samefileexception import SameFileException
from mp3wav.exceptions.overwriteexception import OverWriteException


def windowTest(qtbot):
    testapp = Mp3WavApp()
    testapp.show()
    qtbot.addWidget(testapp)
    assert testapp.isVisible()
    assert testapp.close()

@pytest.mark.qt_no_exception_capture
def fileTypeTest(qtbot, tmpdir):
    testapp = Mp3WavApp()
    qtbot.addWidget(testapp)
    infile = tmpdir.mkdir("files").join("demo.mp3")
    infile.write("something")
    testapp.inputFileLine.setText(str(tmpdir.join("files", "demo.mp3")))
    testapp.outputFileLine.setText(str(tmpdir.join('files')))
    testapp.outputFileLineName.setText('demo.wave')
    with pytest.raises(FileTypeException) :
        qtbot.mouseClick(testapp.conversionButton, Qt.LeftButton)

这是自定义异常

import os
import sys
from mp3wav.exceptions.errordialog import ErrorDialog

class FileTypeException(Exception):
    def __init__(self, sid, parent=None):
        super(FileTypeException, self).__init__()
        filetype = "mp3"
        if sid==2:
            filetype = "wav"
        errorMessage = "The Selected file is not "+filetype+\
        "\nSelect the appropriate file"
        if parent:
            dialog = ErrorDialog(parent, errorMessage)
            dialog.show()
            dialog.exec_()
        else:
            print(errorMessage)

我认为它失败了，因为对话框在测试运行期间出现，我需要手动关闭它。但我不知道测试失败的确切原因..

任何人都可以引导我走上正确的道路..非常感谢..
