Appium Find element issues, work sometimes and fails again

Lalit_Garg 2017-10-24 18:33:32 UTC #1

Hi All,

I am facing issue while trying to locate an element in a list view.
Sometime it works and it fails in the next iteration.
I have used “id” as a locator and as well as xpath in next iteration. But it fails intermittently in both cases.
Much appreciate help.

Share your desired capabilities here and is the element viewable on screen or is it visible after a scroll?

Lalit_Garg 2017-10-25 15:17:50 UTC #3

{
“platformName”: “Android”,
“deviceName”: “Samsung S6”,
“app”: “/Users/LKG0716/LALIT/Projects/ToolConnect/Automation/Apps/app-debug_124.apk”,
“platformVersion”: “8.0”,
“noReset”: true,
“udid”: “FA71A0303273”
}

Yes, the element is viewable on screen. I do not need to do any scroll.

Venkatesh_Akula 2017-10-25 15:41:35 UTC #4

Can you add this to your desired capabilities since your device os is higher than 7.0

automationName: UiAutomator2

Lalit_Garg 2017-10-25 16:13:50 UTC #5

I have added the “automationName: UiAutomator2” now, but started getting another error.

Initializing the driver
Exception in initializing Android Driver : An unknown server-side error occurred while processing the command. Original error: JAVA_HOME is not set currently. Please set JAVA_HOME. (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 7.88 seconds

I have set the java_home environment variable in eclipse and also in bash_profile file.

Lalit_Garg 2017-10-25 16:14:37 UTC #6

Venkatesh_Akula 2017-10-25 16:29:24 UTC #7

just to confirm this should be

"automationName": "UiAutomator2",

For JAVA_HOME I have this in my .bash_profile

export JAVA_HOME=$(/usr/libexec/java_home)
export PATH=${PATH}$JAVA_HOME/bin

Lalit_Garg 2017-10-25 17:16:11 UTC #8

I have the same capabilities as you mentioned.

caps.setCapability(“automationName”, “UiAutomator2”);

LKG0716@Lalits-MacBook-Pro:~$ cat .bash_profile
export ANDROID_HOME=/Users/LKG0716/Library/Android/sdk
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$JAVA_HOME/bin

Venkatesh_Akula 2017-10-25 17:20:10 UTC #9

npm install -g appium-doctor

then run the below command in terminal. It will list out all the errors, fix them all.

appium-doctor

Lalit_Garg 2017-10-25 18:56:46 UTC #10

Lalit_Garg 2017-10-25 18:57:09 UTC #11

appium-doctor does not have java_home problem. But eclipse still shows the same issue

Lalit_Garg 2017-10-25 19:57:52 UTC #12

Thanks much Venkatesh, It works now. Not sure the reason, but I had to close my android studio which was running.
Restarting eclipse didn’t help.

vasu 2017-11-01 13:41:07 UTC #13

Hi lalit same switch problem is there i am add the dc.setCapability(“automationName”, “UiAutomator2”);

i run the script appum logs error will comeing on below

vasu 2017-11-01 13:41:55 UTC #14

Venkatesh_Akula 2017-11-02 06:45:01 UTC #15

The log shows that you should include platformName capability, attached your screenshot with error highlighted.

vasu 2017-11-02 06:47:58 UTC #16

i am mention platform name capability in below
dc = new DesiredCapabilities();;
//dc.setCapability(“deviceName”, “F9AZCY17X014”);
//dc.setCapability(“platformVersion”, “5.0.2”);
dc.setCapability(“deviceName”, “emulator-5554”);
dc.setCapability(“platformVersion”, “7.0”);
dc.setCapability(“platformName”, “Android”);
dc.setCapability(“automationName”, “UiAutomator2”);
dc.setCapability(“noReset”, “True”);
dc.setCapability(“fullReset”, “False”);
dc.setCapability(“appPackage”, “com.livenation.mobile.android.na”);
dc.setCapability(“appActivity”, “com.livenation.mobile.android.na.MainActivity”);

vasu 2017-11-02 06:48:57 UTC #17

it will be comeing on error in venkatesh

I am getting issues on finding elements in iOS 11.
For example, in the attached screenshot, I want to find element for the tool name, which is ‘BAT’ now. This may change and so will be the xpath. The accessibility id added by the developer does not work as well.

Venkatesh_Akula 2017-11-16 18:50:47 UTC #19

Hi Lalit, I too faced a similar problem. The best solution here is to ask your development team to implement generic accessibility id’s for these kind of fields.

For example in your case, they can name it tool_name. Once its implemented you can do

self.driver.find_element_by_id('tool_name')

Fo now you can select it using xpath
Sample:

//*/XCUIElementTypeTable/XCUIElementTypeCell[2]/XCUIElementTypeStaticText[2]

Lalit_Garg 2017-11-16 20:01:57 UTC #20

The development team had added accessibility id for some elements. But I could see that id in appium gui.

And the xpath, I am seeing from appium gui is like below:
//XCUIElementTypeStaticText[@name=“BAT”]
I do not see a tree like structured xpath.
