qtchecker 0.3.0

简介

这是一个简单的助手模块，用于执行PyQt GUI测试。在

使用qtchecker模块作为其用户

1. 使用全局QApplication对象和给定的测试过的QWidget对话框参数创建QtChecker对象
2. 使用setChecks()方法和以下帮助程序类定义检查序列：

• AttrCheck-读取测试的对话框属性值
• CmdCheck-执行一个经过测试的对话框命令并读取其结果值
• WrapAttrCheck-对测试的对话框属性执行包装器命令
• WrapCmdCheck-对测试的对话框命令的结果值执行包装命令
• ExtAttrCheck-读取在对话框外部定义的外部属性值
• ExtCmdCheck-执行在对话框外部定义的外部命令并读取其结果值

1. 启动事件循环并使用executeChecks()或executeChecksAndClose()方法执行检查
2. 通过读取执行的results属性来比较结果

例如

importunittestfromPyQt5importQtGuifromPyQt5importQtCorefromPyQt5importQtTestfromqtchecker.qtCheckerimportQtChecker,CmdCheck,WrapAttrCheck,ExtCmdCheck# import my dialog modulefromlavuelibimportliveViewer# QApplication object should be one for all tessapp=QtGui.QApplication([])classGuiTest(unittest.TestCase):def__init__(self,methodName):unittest.TestCase.__init__(self,methodName)deftest_run(self):# my tested MainWindow dialogdialog=liveViewer.MainWindow()dialog.show()# create QtChecker objectqtck=QtChecker(app,dialog)# define a sequence of action of the dialogqtck.setChecks([# read return value of execute isConnected commandCmdCheck(# a python path to a method executed in the first action"_MainWindow__lavue._LiveViewer__sourcewg.isConnected"),# click pushButton with the left-mouse-clickWrapAttrCheck(# a python path to an pushButton object"_MainWindow__lavue._LiveViewer__sourcewg._SourceTabWidget__sourcetabs[],0._ui.pushButton",# Wrapper command to be executed on the action objectQtTest.QTest.mouseClick,# additional parameters of the wrapper command[QtCore.Qt.LeftButton]),# read a result of external "getLAvueState" commandExtCmdCheck(# parent object of the external commandself,# external command name"getLavueState"),])# execute the check actions and close the dialogstatus=qtck.executeChecksAndClose()self.assertEqual(status,0)# compare results returned by each actionqtck.compareResults(self,[# a result of isConnected() commandTrue,# a result of the mouseClick on the pushButtonNone,# a result of getLavueState() command'{"connected": false}'])defgetLavueState(self):""" an external command """importtangoreturntango.DeviceProxy("po/lavuecontroller/1").LavueState
