java-client

This is the Java language bindings for writing Appium Tests that conform to WebDriver Protocol

v8 to v9 Migration

Since v9 the client only supports Java 11 and above. Follow the v8 to v9 Migration Guide to streamline the migration process.

v7 to v8 Migration

Since version 8 Appium Java Client had several major changes, which might require to update your client code. Make sure to follow the v7 to v8 Migration Guide to streamline the migration process.

Why is it so complicated?

Selenium client does not follow Semantic Versioning, so breaking changes might be introduced even in patches, which requires the Appium team to update the Java client in response.

How to pin Selenium dependencies?

Appium Java Client declares Selenium dependencies using an open version range which is handled differently by different build tools. Sometimes users may want to pin used Selenium dependencies for various reasons. Follow the Transitive Dependencies Management article for more information about establishing a fixed Selenium version for your Java test framework.

Drivers Support

Appium java client has dedicated classes to support the following Appium drivers:

To automate other platforms that are not listed above you could use AppiumDriver or its custom derivatives.

Appium java client is built on top of Selenium and implements the same interfaces that the foundation RemoteWebDriver does. However, Selenium lib is mostly focused on web browser automation while Appium is universal and covers a wide range of possible platforms, e.g. mobile and desktop operating systems, IOT devices, etc. Thus, the foundation AppiumDriver class in this package extends RemoteWebDriver with additional features, and makes it more flexible, so it is not so strictly focused on web-browser related operations.

Appium Server Service Wrapper

Appium java client provides a dedicated class to control Appium server execution. The class is AppiumDriverLocalService. It allows to run and verify the Appium server locally from your test framework code and provides several convenient shortcuts. The service could be used as below:

AppiumDriverLocalService service = AppiumDriverLocalService.buildDefaultService();
service.start();
try {
    // do stuff with drivers
} finally {
    service.stop();
}

You could customize the service behavior, for example, provide custom command line arguments or change paths to server executables using AppiumServiceBuilder

Note

AppiumDriverLocalService does not support server management on non-local hosts

Usage Examples

UiAutomator2

UiAutomator2Options options = new UiAutomator2Options()
    .setUdid("123456")
    .setApp("/home/myapp.apk");
AndroidDriver driver = new AndroidDriver(
    // The default URL in Appium 1 is http://127.0.0.1:4723/wd/hub
    new URI("http://127.0.0.1:4723").toURL(), options
);
try {
    WebElement el = driver.findElement(AppiumBy.xpath("//Button"));
    el.click();
    driver.getPageSource();
} finally {
    driver.quit();
}

XCUITest

XCUITestOptions options = new XCUITestOptions()
    .setUdid("123456")
    .setApp("/home/myapp.ipa");
IOSDriver driver = new IOSDriver(
    // The default URL in Appium 1 is http://127.0.0.1:4723/wd/hub
    new URI("http://127.0.0.1:4723").toURL(), options
);
try {
    WebElement el = driver.findElement(AppiumBy.accessibilityId("myId"));
    el.click();
    driver.getPageSource();
} finally {
    driver.quit();
}

Any generic driver that does not have a dedicated class

BaseOptions options = new BaseOptions()
    .setPlatformName("myplatform")
    .setAutomationName("mydriver")
    .amend("mycapability1", "capvalue1")
    .amend("mycapability2", "capvalue2");
AppiumDriver driver = new AppiumDriver(
    // The default URL in Appium 1 is http://127.0.0.1:4723/wd/hub
    new URI("http://127.0.0.1:4723").toURL(), options
);
try {
    WebElement el = driver.findElement(AppiumBy.className("myClass"));
    el.click();
    driver.getPageSource();
} finally {
    driver.quit();
}

Check the corresponding driver's READMEs to know the list of capabilities and features it supports.

You can find many more code examples by checking client's unit and integration tests.

Troubleshooting

InaccessibleObjectException is thrown in runtime if Java 16+ is used

Appium Java client uses reflective access to private members of other modules to ensure proper functionality of several features, like the Page Object model. If you get a runtime exception and InaccessibleObjectException is present in the stack trace and your Java runtime is at version 16 or higher, then consider the following Oracle's tutorial and/or checking existing issues for possible solutions. The idea there would be to explicitly allow access for particular modules using --add-exports/--add-opens command line arguments.

Another possible, but weakly advised solution, would be to downgrade Java to version 15 or lower.

Issues related to environment variables' presence or to their values

Such issues are usually the case when the Appium server is started directly from your framework code rather than run separately by a script or manually. Depending on the way the server process is started it may or may not inherit the currently active shell environment. That is why you may still receive errors about the variables' presence even though these variables are defined for your command line interpreter. Again, there is no universal solution to that, as there are many ways to spin up a new server process. Consider checking the Appium Environment Troubleshooting document for more information on how to debug and fix process environment issues.
