对于我们的BDD测试,我们使用与selenium 2 webdriver(本例中为Chrome驱动程序)对话的Specflow。
在本地主机上运行时(是的,“它在我的机器上工作”已经在对话中出现了几次)测试工作正常。他们设置数据和新的webdriver,进行测试,然后拆除webdriver和数据。即使测试出现严重错误,因为我使用了正确的属性,但总是会被击倒,因此driver.Quit()
会破坏浏览器和驱动程序。
当我使用我们的持续集成[TeamCity]在我们的服务器[Windows Server 2008 r2]上运行它时,会出现问题。由于某种原因,它将开始运行多个驱动程序实例,导致测试失败。
之前是否有人遇到此问题并找到修复程序?我们需要一个使用不 HtmlUnitDriver
的驱动程序的解决方案。
额外信息:
编辑:
Webdriver的设置是通过确保它尚未创建,然后创建ChromeDriver
的新实例。伪/真实代码示例下面显示了它的设置,抱歉我不能显示完整的代码,因为我们使用其他选项,我们坚持使用(例如zap或fiddler集成/语言更改等)。
设置
[SetUp]
[BeforeScenario()]
public static void BeforeWebScenario()
{
if driver == null
driver = new ChromeDriver();
// Code to start page
}
撕下
[TearDown]
[AfterScenario()]
public static void AfterWebScenario()
{
try
{
driver.Quit();
} catch (Exception)
{
throw Exception
}
driver = null;
}

我也有这个问题。我通过在testSetup()方法中杀死任何正在运行的chromedriver.exe实例来修复它。我使用VBScript和一些Groovy代码来运行脚本。对不起,这个答案有点长。
我在我的setUp中有这个:
if (wshsc.isRunningByCommandLineContents("chromedriver.exe"))
wshsc.killProcessByCommandLineContents("chromedriver.exe")
isRunningByCommandLineContents:
If WScript.Arguments.Count = 1 Then
strCmdLine = WScript.Arguments.Item(0)
On Error Resume Next
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set objShell = CreateObject("WScript.Shell")
Set colProcessList = objWMIService.ExecQuery _
("Select * from Win32_Process")
If colProcessList.Count > 0 Then
For Each objItem in colProcessList
If (InStr(objItem.CommandLine, strCmdLine)) Then
If (InStr(objItem.CommandLine, "cscript")) Then
Else
WScript.StdOut.Write "A process is running with " + strCmdLine + " in its command line = " + objItem.Name
End If
End If
Next
End If
End If
killProcessByCommandLineContents:
If WScript.Arguments.Count = 1 Then
strProcess = WScript.Arguments.Item(0)
On Error Resume Next
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set objShell = CreateObject("WScript.Shell")
Set colProcessList = objWMIService.ExecQuery _
("Select * from Win32_Process")
If colProcessList.Count > 0 Then
For Each objItem in colProcessList
If InStr(objItem.CommandLine, strProcess) Then
If (InStr(objItem.CommandLine, "cscript")) Then
Else
WScript.StdOut.Write objItem.Name + " "
objItem.Terminate()
End If
End If
Next
Else
WScript.StdOut.Write "No instances found running"
End If
Else
WScript.StdOut.Write "Bad Arguments"
End If
"运行脚本部分":
public void killProcessByCommandLineContents(String contents) {
List<String> arg = new ArrayList<String>()
arg.add(contents)
String [] args = arg.toArray()
runScript("killByCmdLineContents.vbs", args, true)
}
public boolean isRunningByCommandLineContents(String contents) {
List<String> arg = new ArrayList<String>()
arg.add(contents)
String [] args = arg.toArray()
String returnData = runScript("IsRunningByCmdLineContents.vbs", args, true)
if (returnData.contains(contents)) {
return true
} else {
return false
}
}

cmdLine.add("C://Windows//System32//cscript.exe")
cmdLine.add(dir + "dir//src//com//misc//wshScripts//" + name)
int index = 0
args.each() {
cmdLine.add(args[index])
index++
}
try {
String [] cmdLineArray = cmdLine.toArray()
Process p = Runtime.getRuntime().exec(cmdLineArray, null);
if (returnOutput) {
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String dataToReturn
Log.logger.info("Standard output: ");
while ((s = stdInput.readLine()) != null) {
Log.logger.info(s)
dataToReturn = s // should get last line
}
Log.logger.info("Standard error: ");
while ((s = stdError.readLine()) != null) {Log.logger.info(s);}
return dataToReturn
} else {
return ""
}
}
catch (IOException e) {
Log.logger.info(e.message, e);
}
}

如果您使用DriverService接口,请保留该服务,直到您完成驱动程序,并调用DriverService.stop()。对我来说,driver.quit()还不够,因为我也在使用DriverService。
driver.close();
driver.quit();
driverService.stop();
