Java-client: IOSDriver cannot be created from AppiumDriverLocalService, because of Problem getting session data for driver type IosDriver

[truebit]

Description

org.openqa.selenium.SessionNotCreatedException: A new session could not be created. Details: Problem getting session data for driver type IosDriver; does it implement 'get driverData'? (WARNING: The server did not provide any stacktrace information)

Environment

• java client build version or git revision if you use some shapshot: 3.4.0
• Appium server version or git revision you is use some shapshot:1.5.0
• Desktop OS/version used to run Appium if necessary:Mac OS X 10.11
• Node.js version (unless using Appium.app|exe) or Appium CLI or Appium.app|exe: 5.6.0
• Mobile platform/version under test: 8.1.1
• Real device or emulator/simulator: iphone 5s
  

  Details

I run my test in testng
I created AppiumDriverLocalService and started() it in @BeforeSuite
then in @BeforeTest I created IOSDriver as follow:

IOSDriver<MobileElement> iosDriver = new IOSDriver<>(getLocalService().getUrl(), desiredCapabilities);

But this statement got stacks

org.openqa.selenium.SessionNotCreatedException: A new session could not be created. Details: Problem getting session data for driver type IosDriver; does it implement 'get driverData'? (WARNING: The server did not provide any stacktrace information)

It seems that something is wrong on the server side. This exception was thrown here: https://github.com/appium/appium/blob/5d324178c8246c0122f5dbc6302fcf24c0322d6a/lib/appium.js#L137

I have no device ti reproduce this problem. @imurchie Any idea?

[TikhomirovSergey]

@truebit
Which capabilities have been provided here (I need Java code)?

IOSDriver<MobileElement> iosDriver = new IOSDriver<>(getLocalService().getUrl(), desiredCapabilities);

[imurchie]

This looks like two sessions happening at once? There is a second session starting here: https://gist.github.com/truebit/f017d57fc887ec0e3be6#file-gistfile1-txt-L139

The error is... odd.

[truebit]

@imurchie yes, It seems that the AppiumDriverLocalService have already created an session. and then IOSDriver tried to create another and failed.

@TikhomirovSergey I wrote a class to read desiredCapabilities from a properties file. The desiredCapabilities could be seen in the log gist actually.

@truebit @imurchie
As I know appium doesn't support the multisession mode yet, am I right?

@truebit
Do these sessions use the same port?

[imurchie]

The infrastructure is there for multisession mode, but it hasn't been ironed out. Also, for iOS it is unlikely to happen until we support something other than Instruments.

[TikhomirovSergey]

@truebit I think the it could work out your problem:

it is possible to create two instance of AppiumDriverLocalServices which can use same binaries and work on different ports.

 new AppiumServiceBuilder().
                    usingAnyFreePort().build().start();

@imurchie @truebit What do you think about this?

[truebit]

Sorry, I have found the root cause.
The server was only launched once, but I created IOSDriver twice. It failed when trying to create another IOSDriver instance

appium 1.5.2

使用 appium --session-override 启动。

第一个session启动正常，在第二个session请求后，并没有覆盖第一个session，直接报错了。
错误信息：
{
"status": 33,
"value": {
"message": "A new session could not be created. Details: Problem getting session data for driver type IosDriver; does it implement 'get driverData'?"
},
"sessionId": null
}

I just restarted appium and it worked for me

hi @imurchie , could you help me how to update Automaion name from "UIAutomation" to "XCUITest" ?

bellow are the appium logs

[ochubey]

Have you tried to define it in Capabilities?
For Java client it's something like capabilities.setCapability("automationName", "XCUITest");

[babusurendra]

Hi @ochubey , I have scripts in ruby and tried the same :automationName => config['XCUITest'] still i am seeing the same

[babusurendra]

can any one help me on this?

[babusurendra]

I have updated the script as :automationName => 'XCUITest' , since dont have the value in config file and now it is working fine
thanks @ochubey !

[ochubey]

@babusurendra U welcome ;)

[babusurendra]

Hi @ochubey , i have xpath like "//UIAApplication[1]/UIAWindow/UIAAlert[contains(@label,'Notifications')] " but this is not working in 1.6 appium when i use "//*[contains(@label,'Notifications')]" it is working fine do we have any solution for this?

[babusurendra]

also below xpath working fine "//XCUIElementTypeApplication[1]/XCUIElementTypeWindow/XCUIElementTypeAlert[contains(@label,'Notifications')]

[shahulprofile]

Run Appium.
It will create new session, Find the port number. (always it will be like - address "127.0.0.1" --robot-
port 4)
Port number should match with the capability.

Example: If my port number is 4, then

    AndroidDriver driver = new AndroidDriver(new URL("http://127.0.0.1:4/wd/hub"),cap);

Thanks,
Shameed.
