Handling webview context switch in parallel

[harigovind]

Hello Masters,

I am trying to run a hybrid app test in parallel involves webview. Problem i am facing whenever i call switchcontext to webview , ChromeDriver is killing existing chromedriver sessions . This will cause other test to fail if they are using chromedriver . All help / hints appreciated

[Chromedriver] Set chromedriver binary as: \AppData\Roaming\npm\node_modules\appium\node_modules\appium-android-driver\node_modules\appium-chromedriver\chromedriver\win\chromedriver.exe
[Chromedriver] Killing any old chromedrivers, running: FOR /F "usebackq tokens=5" %a in (netstat -nao ^| findstr /R /C:"9515 ") do (FOR /F "usebackq" %b in (TASKLIST /FI "PID eq %a" ^| findstr /I chromedriver.exe) do (IF NOT %b=="" TASKKILL /F /PID %a))

it's always starting chromedriver on 9515 port, I wonder if there a way to start in user defined port every time ?

Solved .. Posting it for others if useful

instead of using Switching using driver.context() , used chromedriver explicitly

File chromeDriverLib = new File("../path/to/chromedriver.exe");
String chromeDriverPath = chromeDriverLib.getAbsolutePath();
System.setProperty("webdriver.chrome.driver", chromeDriverPath);

		ChromeDriverService service = new ChromeDriverService.Builder().usingDriverExecutable(chromeDriverLib)
				.usingAnyFreePort().build();
		service.start();

		Proxy proxy = new Proxy();
		proxy.setHttpProxy(driver.getRemoteAddress().toString());
		ChromeOptions chromeOptions = new ChromeOptions();
		chromeOptions.setExperimentalOption("androidPackage", "app.package.name");
		chromeOptions.setExperimentalOption("androidDeviceSerial", deviceID);
		chromeOptions.setExperimentalOption("androidUseRunningApp", true);

		DesiredCapabilities capabilities = new DesiredCapabilities();
		capabilities.setCapability(CapabilityType.PROXY, proxy);
		capabilities.setCapability("chromeOptions", chromeOptions);
		WebDriver chromeDriver = new RemoteWebDriver(service.getUrl(), capabilities);

                    <do webview test steps>
                  service.stop();
                   <continue Native test steps>

This has solved my problems and it's stable as well .
