Mobile device allocation plugin is not working as expected when running test in parallel

TC1 : Login with Native customer TC2 : Login with Hybrid customer (password field is part of webview) TC3 : Login and validate place order

If i run above 3 test cases in parallel on 2 device and lets say TC1 and TC2 have started execution on 2 devices, TC1 has finished execution and waiting on TC3 to start, before TC3 start TC2 on other device which is still executing will immediately failed with error “org.openqa.selenium.WebDriverException: Connection refused (Connection refused)”

Note : Running above all 3 test cases on 1 device using same runner class works fine.

What i noticed is when running more than 3 test cases on 2 devices and 1 device has finished execution on 1 device and 2nd device still running test case will immediately failed waiting on 3rd test case to start execution on any 1 of this device.

Solution : When 2 test cases running in parallel on 2 devices, 1 has finished execution and another one still running should not affect waiting on 3rd test case to start execution on available device 1

====== If not Connection Refused this error will throw ======

[LearningPur]

Thank you so much @prashant-ramcharan for giving your golden time to look into it and help me identify the silly mistake i made which took me few days though couldn’t resolved it.

I made the changes what you mentioned in your comment above and it has resolved an issue.

Thanks a ton, you don’t know how much you helped me and saved me in this project.

In future if i will be given a chance i would love to meet you in person and touch your feet.

[prashant-ramcharan]

@LearningPur I had a quick look and this is not an issue with Courgette.

The issue is you killing all Appium servers before each test so this will conflict when you have an active server running a test.

Remove the before all method killRunningAppiumServer as this is where the issue is.

If you want to kill all appium servers after all tests are complete then you should move this code to a @CourgetteAfterAll hook.

Some additional tips:

Remove these caps

chromedriverUseSystemExecutable
chromedriverExecutable
chromeDriverPort

Update the service builder

        serviceBuilder
                .usingAnyFreePort()
                .withArgument(() -> "--allow-insecure","chromedriver_autodownload");
