Appium 1.7.0 crashes Java client 5.0.3 when testing iOS

Question

Appium 1.7.0 crashes Java client 5.0.3 when testing iOS

welnanick opened this issue 7 years ago · 26 comments

Description

When attempting to use java-client 5.0.3 to test an iOS device with Appium 1.7.0, the java-client crashes with java.lang.NullPointerException: null value in entry: browserName=null

Environment

java client build version or git revision if you use some shapshot: 5.0.3
Appium server version or git revision if you use some shapshot: 1.7.0
Desktop OS/version used to run Appium if necessary: macOS Sierra 10.12.6
Node.js version (unless using Appium.app|exe) or Appium CLI or Appium.app|exe: Node.js v8.5.0, Appium 1.7.0
Mobile platform/version under test: iOS
Real device or emulator/simulator: Real Device

Details

Using the same Appium Server, I can use appium-desktop using the custom server option to connect to the iOS device just fine. Android is unaffected. I believe this chunk of the logs are could relevant:

Answer 1 · 2017-09-20T09:37:40.000Z

@welnanick I think that something is wrong on the server side.
@SrinivasanTarget could you check session details on iOS with server 1.7.0

Answer 2 · 2017-09-20T09:42:47.000Z

@welnanick Can you please attach full server log? It seems like you don't provide all the required capabilities.

Answer 3 · 2017-09-20T09:50:33.000Z

@TikhomirovSergey iOS works fine with 1.7.0 and latest java client. @welnanick can you share your sample driver creation code as @mykola-mokhnach suggested along with the pom or gradle file.

Answer 4 · 2017-09-20T16:36:04.000Z

Here is the code I am using to create the driver:

        AppiumDriver<MobileElement> driver = null;

        DesiredCapabilities capabilities = new DesiredCapabilities();
        Assert.assertNotNull("platformName is a required argument", System.getProperty("platformName"));
        capabilities.setCapability("platformName", System.getProperty("platformName"));
        if (System.getProperty("platformName").equals("Android")) {

            capabilities.setCapability("appWaitActivity", System.getProperty("appWaitActivity"));
            capabilities.setCapability("app", System.getProperty("appAndroid"));


        }
        else if (System.getProperty("platformName").equals("iOS")) {

            capabilities.setCapability("app", System.getProperty("appiOS"));
            capabilities.setCapability("automationName", System.getProperty("automationName"));
            capabilities.setCapability("xcodeOrgId", System.getProperty("xcodeOrgId"));
            capabilities.setCapability("xcodeSigningId", System.getProperty("xcodeSigningId"));
            capabilities.setCapability("usePrebuiltWDA", System.getProperty("usePrebuiltWDA"));

        }
        capabilities.setCapability("deviceName", System.getProperty("deviceName"));
        Assert.assertNotNull("udid is a required argument", System.getProperty("udid"));
        capabilities.setCapability("udid", System.getProperty("udid"));

        try {
            if (System.getProperty("platformName").equals("iOS")) {
                driver = new IOSDriver<>(new URL(System.getProperty("appiumLocation")), capabilities);
            }
            else {
                driver = new AndroidDriver<>(new URL(System.getProperty("appiumLocation")), capabilities);
            }

        }
        catch (MalformedURLException e) {

            e.printStackTrace();

        }

        if (driver != null) {

            driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

        }

        return driver;

With all the system properties defined the above code should result in the following capabilities:

{
  "platformName": "iOS",
  "app": "/Users/nwelna/Documents/app-test-automation/appFiles/ios/app.ipa",
  "automationName": "XCUITest",
  "udid": "67e44e99a952683ca27e8beccc50687bf4a71490",
  "deviceName": "iPhone",
  "updatedWDABundleId": "com.WebDriverAgentRunner",
  "xcodeOrgId": "*orgId*",
  "xcodeSigningId": "iPhone Developer",
  "usePrebuiltWDA": true
}

Again this works for Android, and not iOS, and it worked fine with 1.7.0 Beta. It wasn't until I updated appium yesterday morning that I started having issues.

Here is a gist of the full appium logs up to the crash using the java-client: gist

Also, just discovered appium-desktop is not working as I thought it was, as it can't interact with the 1.7.0 server, so I can't send commands.

Answer 5 · 2017-09-20T17:00:19.000Z

Oh, here are my dependencies in gradle:

dependencies {

    testCompile group: 'org.testng', name: 'testng', version: '6.12'
    testCompile group: 'io.appium', name: 'java-client', version: '5.0.3'
    testCompile group: 'com.codepine.api', name: 'testrail-api-java-client', version: '2.0.0'

}

Answer 6 · 2017-09-20T17:01:35.000Z

@welnanick i will check in sometime and update you.

Answer 7 · 2017-09-20T18:13:30.000Z

@TikhomirovSergey the exception is thrown inside:

    default Map<String, Object> getSessionDetails() {
        Response response = execute(GET_SESSION);
        return  ImmutableMap.<String, Object>builder()
                .putAll(Map.class.cast(response.getValue())).build();
    }

We try to create immutable map on response values, but there is a key with null value there and this causes failure. Probably, it is necessary to perform some preliminary filtering before calling putAll

Answer 8 · 2017-09-20T22:09:51.000Z

@mykola-mokhnach Maybe. I will try to improve it soon.

@welnanick said

Again this works for Android, and not iOS, and it worked fine with 1.7.0 Beta. It wasn't until I updated appium yesterday morning that I started having issues.

So this is really intresting deatail

Answer 9 · 2017-09-20T22:16:51.000Z

...maybe some empty string was there

Answer 10 · 2017-09-27T04:49:31.000Z

Fix is going to be published..

Answer 11 · 2017-09-28T16:01:18.000Z

@TikhomirovSergey is there an ETA for when the fix will be published? My iOS testing is currently completely halted due to this bug.

Answer 12 · 2017-09-29T04:31:56.000Z

@welnanick We are planning to release 5.1.0 or 5.0.4 soon though there is no exact ETA. I wanted test everything on Selenium 3.6.0 released yesterday before we make a java-client 5.1.0 or 5.0.4. Will keep you posted.

Answer 13 · 2017-09-29T10:58:44.000Z

@SrinivasanTarget I've encountered same problem with NullPointerException when using sendKeys() method and Selenium 3.6.0. After downgrading Selenium to 3.4.0 it seems to work properly, so it might be worth looking into.

Versions:
Appium: 1.7.1
java-client: 4.1.2
Android: 7.1

Answer 14 · 2017-09-29T11:01:56.000Z

I don't expect any issues as there is not much changes in Selenium 3.6.0. Will check it though. I think you should give a try in latest java client without excluding selenium and adding it again.It should working without any efforts.

Answer 15 · 2018-02-28T09:06:06.000Z

I had recently updated to Xcode 9.2. Appium 1.6.3 was not compatible with this Xcode version.
Finally after trying out adifferent versions of appium and java-client and selenium, I found the versions which are working.
I was getting a browserName=null exception while contacting the appium server from the java code before.

Here are the versions which are working with Xcode 9.2
Appium - 1.7.1
Java-client - 5.0.0-BETA7
selenium-java- 3.4.0

@kumarRaghavendra Unfortunately cant help anything here. Give a try in latest java client and raise us issues if you hit any with detailed server logs.

Answer 20 · 2018-04-11T09:06:25.000Z

Hello I also had some issues, the only way that I make the test cases work is using the following configuration:

Xcode version 9.3
selenium-java 3.4.0
io.appium java-client 5.0.0-BETA7
Appium server 1.7.1

I tried a lots of combinations and this one is more or less working. The test cases fails, seems like some elements are not recognized. I am investigating why. For example, If I change the appium version to 5.0.4 the elements are not recognized:
Message: org.openqa.selenium.WebDriverException: Returned value cannot be converted to WebElement: {ELEMENT=C0929175-9F93-4175-B0F6-F3F597A8BD79} Build info: version: '3.4.0', revision: 'unknown', time: 'unknown' System info: host: os.name: 'Mac OS X', os.arch: 'x86_64', os.version: '10.13.2', java.version: '1.8.0_151' Driver info: driver.version: IOSDriver Stack Trace: org.openqa.selenium.remote.RemoteWebDriver.findElement(RemoteWebDriver.java:417) io.appium.java_client.DefaultGenericMobileDriver.findElement(DefaultGenericMobileDriver.java:62) io.appium.java_client.AppiumDriver.findElement(AppiumDriver.java:1) io.appium.java_client.ios.IOSDriver.findElement(IOSDriver.java:1) org.openqa.selenium.remote.RemoteWebDriver.findElementById(RemoteWebDriver.java:453) io.appium.java_client.DefaultGenericMobileDriver.findElementById(DefaultGenericMobileDriver.java:70) io.appium.java_client.AppiumDriver.findElementById(AppiumDriver.java:1) io.appium.java_client.ios.IOSDriver.findElementById(IOSDriver.java:1) org.openqa.selenium.By$ById.findElement(By.java:218) org.openqa.selenium.remote.RemoteWebDriver.findElement(RemoteWebDriver.java:402) io.appium.java_client.DefaultGenericMobileDriver.findElement(DefaultGenericMobileDriver.java:58) io.appium.java_client.AppiumDriver.findElement(AppiumDriver.java:1) io.appium.java_client.ios.IOSDriver.findElement(IOSDriver.java:1) org.openqa.selenium.support.pagefactory.DefaultElementLocator.findElement(DefaultElementLocator.java:69) org.openqa.selenium.support.pagefactory.internal.LocatingElementHandler.invoke(LocatingElementHandler.java:38)

On the other hand, I couldn't start the selenium-java to an upper version I have this issue:

Answer 23 · 2018-05-16T12:34:44.000Z

Hi,
I haven a problem I think is related to the fix for this issue. Ever since java-client:5.0.4 and upwards getSession() is called between each command to merge in my Desired Capabilities, severely increasing the test time. I have isolated the problem to a change between java-client version 5.0.3 and 5.0.4 and it still persists in the latest BETA version of java-client. It only occurs on iOS devices and only starts occurring when the java-client version is upped (nothing else changed). Is there some way to avoid this behavior?

Xcode version 9.2
iOS 11.2.5
selenium-java 3.11.0
io.appium java-client 6.0.0-BETA5
Appium server 1.7.2
