I guess, below row
driver = new IOSDriver(new URL(“http://127.0.0.1:4327/wd/hub”), capabilities);
is missing in @BeforeClass

3

tried with this…still no improvments .Pls help

4

@neha can you provide your whole @beforeClass method?

I launch the appium server ,click on inspector and then run the below java code

Can you just start the appium server and run the java code (without launching the inspector) ?

P.S: It’s not related to your problem (for now), but it seems to me that the path you specified in your appDir variable is missing a “/” in first ( “/Users/Vikas/Downloads/Quotiful.app”)

P.S 2: why do you have your @AfterClass method inside the @BeforeClass one?

i have literally tried everything… my automation was running seamlessly before and literally it stopped working suddenly…

on my IDE … it shows…
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

below are the appium logs…

i am not able to debug

Here is the command that is failing:

What happens if you run that (without quotes) from the terminal? Also, is ‘com.examsoft.SofTestMV12’ the correct bundle id? Instruments doesn’t seem to like it.

9

Yes i tried… that did not work , and the Bundle id is correct !!
in the end i set up my machine again …

Sometimes that’s the best way. Glad it’s working for you.
