Appium Desired Capabilities

General Capabilities

Capability	Description	Values
automationName	Which automation engine to use	Appium (default), or UiAutomator2, Espresso, or UiAutomator1 for Android, or XCUITest or Instruments for iOS, or YouiEngine for application built with You.i Engine
platformName	Which mobile OS platform to use	iOS, Android, or FirefoxOS
platformVersion	Mobile OS version	e.g., 7.1, 4.4
deviceName	The kind of mobile device or emulator to use	iPhone Simulator, iPad Simulator, iPhone Retina 4-inch, Android Emulator, Galaxy S4, etc… On iOS, this should be one of the valid devices returned by instruments with instruments -s devices. On Android this capability is currently ignored, though it remains required.
app	The absolute local path or remote http URL to a .ipa file (IOS), .app folder (IOS Simulator), .apk file (Android) or .apks file (Android App Bundle), or a .zip file containing one of these. Appium will attempt to install this app binary on the appropriate device first. Note that this capability is not required for Android if you specify appPackage and appActivity capabilities (see below). UiAutomator2 and XCUITest allow to start the session without app or appPackage. Incompatible with browserName. See here about .apks file.	/abs/path/to/my.apk or http://myapp.com/app.ipa
otherApps	App or list of apps (as a JSON array) to install prior to running tests. Note that it will not work with automationName of Espresso and iOS real devices	e.g., “/path/to/app.apk”, https://www.example.com/url/to/app.apk, [“http://appium.github.io/appium/assets/TestApp9.4.app.zip”, “/path/to/app-b.app”]
browserName	Name of mobile web browser to automate. Should be an empty string if automating an app instead.	‘Safari’ for iOS and ‘Chrome’, ‘Chromium’, or ‘Browser’ for Android
newCommandTimeout	How long (in seconds) Appium will wait for a new command from the client before assuming the client quit and ending the session	e.g. 60
language	Language to set for iOS (XCUITest driver only) and Android.	e.g. fr
locale	Locale to set for iOS (XCUITest driver only) and Android. fr_CA format for iOS. CA format (country name abbreviation) for Android	e.g. fr_CA, CA

fullReset	Perform a complete reset.	true, false
eventTimings	Enable or disable the reporting of the timings for various Appium-internal events (e.g., the start and end of each command, etc.). Defaults to false. To enable, use true. The timings are then reported as events property on response to querying the current session.	e.g., true
enablePerformanceLogging	(Web and webview only) Enable Chromedriver’s (on Android) or Safari’s (on iOS) performance logging (default false)	true, false
printPageSourceOnFindFailure	When a find operation fails, print the current page source. Defaults to false.	e.g., true
clearSystemFiles	Delete any generated files at the end of a session. Default to false.	true, false
settings[settingsKey]	Update Appium Settings on session creation.	e.g., ‘settings[mjpegScalingFactor]’: 10, ‘settings[shouldUseCompactResponses]’: true

Android Only

These Capabilities are available only on Android-based drivers like UiAutomator2

Capability	Description	Values
appActivity	Activity name for the Android activity you want to launch from your package. This often needs to be preceded by a . (e.g., .MainActivity instead of MainActivity). By default this capability is received from the package manifest (action: android.intent.action.MAIN , category: android.intent.category.LAUNCHER)	MainActivity, .Settings
appPackage	Java package of the Android app you want to run. By default this capability is received from the package manifest (@package attribute value)	com.example.android.myApp, com.android.settings
appWaitActivity	Activity name/names, comma separated, for the Android activity you want to wait for. By default the value of this capability is the same as for appActivity. You must set it to the very first focused application activity name in case it is different from the one which is set as appActivity if your capability has appActivity and appPackage. You can also use wildcards (*).	SplashActivity, SplashActivity,OtherActivity, *, *.SplashActivity
appWaitPackage	Java package of the Android app you want to wait for. By default the value of this capability is the same as for appActivity	com.example.android.myApp, com.android.settings

adbPort	Port used to connect to the ADB server (default 5037)	5037
systemPort	systemPort used to connect to appium-uiautomator2-server or appium-espresso-driver. The default is 8200 in general and selects one port from 8200 to 8299 for appium-uiautomator2-server, it is 8300 from 8300 to 8399 for appium-espresso-driver. When you run tests in parallel, you must adjust the port to avoid conflicts. Read Parallel Testing Setup Guide for more details.	e.g., 8201
remoteAdbHost	Optional remote ADB server host	e.g.: 192.168.0.101
androidDeviceSocket	Devtools socket name. Needed only when tested app is a Chromium embedding browser. The socket is open by the browser and Chromedriver connects to it as a devtools client.	e.g., chrome_devtools_remote

keystorePassword	Password for custom keystore	e.g., foo
keyAlias	Alias for key	e.g., androiddebugkey
keyPassword	Password for key	e.g., foo
chromedriverExecutable	The absolute local path to webdriver executable (if Chromium embedder provides its own webdriver, it should be used instead of original chromedriver bundled with Appium)	/abs/path/to/webdriver
chromedriverArgs	An array of arguments to be passed to the chromedriver binary when it’s run by Appium. By default no CLI args are added beyond what Appium uses internally (such as --url-base, --port, --adb-port, and --log-path.	e.g., ["–disable-gpu", “–disable-web-security”]
chromedriverExecutableDir	The absolute path to a directory to look for Chromedriver executables in, for automatic discovery of compatible Chromedrivers. Ignored if chromedriverUseSystemExecutable is true	/abs/path/to/chromedriver/directory
chromedriverChromeMappingFile	The absolute path to a file which maps Chromedriver versions to the minimum Chrome that it supports. Ignored if chromedriverUseSystemExecutable is true	/abs/path/to/mapping.json
chromedriverUseSystemExecutable	If true, bypasses automatic Chromedriver configuration and uses the version that comes downloaded with Appium. Ignored if chromedriverExecutable is set. Defaults to false	e.g., true
autoWebviewTimeout	Amount of time to wait for Webview context to become active, in ms. Defaults to 2000	e.g. 4
chromedriverPort	Numeric port to start Chromedriver on. Note that use of this capability is discouraged as it will cause undefined behavior in case there are multiple webviews present. By default Appium will find a free port.	e.g. 8000
chromedriverPorts	A list of valid ports for Appium to use for communication with Chromedrivers. This capability supports multiple webview scenarios. The form of this capability is an array of numeric ports, where array items can themselves be arrays of length 2, where the first element is the start of an inclusive range and the second is the end. By default, Appium will use any free port.	e.g. [8000, [9000, 9005]]
ensureWebviewsHavePages	Whether or not Appium should augment its webview detection with page detection, guaranteeing that any webview contexts which show up in the context list have active pages. This can prevent an error if a context is selected where Chromedriver cannot find any pages. Defaults to false	e.g. true
webviewDevtoolsPort	To support the ensureWebviewsHavePages feature, it is necessary to open a TCP port for communication with the webview on the device under test. This capability allows overriding of the default port of 9222, in case multiple sessions are running simultaneously (to avoid port clash), or in case the default port is not appropriate for your system.	e.g. 9543
enableWebviewDetailsCollection	Enables collection of detailed WebView information via /json/version CDP (Chrome Developer Protocol) endpoint since Appium 1.18.0+. This helps to properly match Chromedriver version which supports the given WebView. Without this flag enabled, Appium tries to guess the version of the WebView based on the version of the corresponding installed package (which usually fails for custom web views). Defaults to false	true or false
dontStopAppOnReset	Doesn’t stop the process of the app under test, before starting the app using adb. If the app under test is created by another anchor app, setting this false, allows the process of the anchor app to be still alive, during the start of the test app using adb. In other words, with dontStopAppOnReset set to true, we will not include the -S flag in the adb shell am start call. With this capability omitted or set to false, we include the -S flag. Default false	true or false
unicodeKeyboard	Enable Unicode input, default false	true or false
resetKeyboard	Reset keyboard to its original state, after running Unicode tests with unicodeKeyboard capability. Ignored if used alone. Default false	true or false
noSign	Skip checking and signing of app with debug keys, will work only with UiAutomator, default false	true or false
ignoreUnimportantViews	Calls the setCompressedLayoutHierarchy() uiautomator function. This capability can speed up test execution, since Accessibility commands will run faster ignoring some elements. The ignored elements will not be findable, which is why this capability has also been implemented as a toggle-able setting as well as a capability. Defaults to false	true or false
disableAndroidWatchers	Disables android watchers that watch for application not responding and application crash, this will reduce cpu usage on android device/emulator. This capability will work only with UiAutomator, default false	true or false
chromeOptions	Allows passing chromeOptions capability for ChromeDriver. For more information see chromeOptions	chromeOptions: {args: [’–disable-popup-blocking’]}
recreateChromeDriverSessions	Kill ChromeDriver session when moving to a non-ChromeDriver webview. Defaults to false	true or false
nativeWebScreenshot	In a web context, use native (adb) method for taking a screenshot, rather than proxying to ChromeDriver. Defaults to false	true or false
androidScreenshotPath	The name of the directory on the device in which the screenshot will be put. Defaults to /data/local/tmp	e.g. /sdcard/screenshots/
autoGrantPermissions	Have Appium automatically determine which permissions your app requires and grant them to the app on install. Defaults to false. If noReset is true, this capability doesn’t work.	true or false
networkSpeed	Set the network speed emulation. Specify the maximum network upload and download speeds. Defaults to full	[‘full’,‘gsm’, ‘edge’, ‘hscsd’, ‘gprs’, ‘umts’, ‘hsdpa’, ‘lte’, ‘evdo’] Check -netspeed option more info about speed emulation for avds
gpsEnabled	Toggle gps location provider for emulators before starting the session. By default the emulator will have this option enabled or not according to how it has been provisioned.	true or false
isHeadless	Set this capability to true to run the Emulator headless when device display is not needed to be visible. false is the default value. isHeadless is also support for iOS, check XCUITest-specific capabilities.	e.g., true
adbExecTimeout	Timeout in milliseconds used to wait for adb command execution. Defaults to 20000	e.g., 50000
localeScript	Sets the locale script	e.g., “Cyrl” (Cyrillic)
skipDeviceInitialization	Skip device initialization which includes i.a.: installation and running of Settings app or setting of permissions. Can be used to improve startup performance when the device was already used for automation and it’s prepared for the next automation. Defaults to false	true or false
chromedriverDisableBuildCheck	Sets the chromedriver flag --disable-build-check for Chrome webview tests	true or false
skipUnlock	Skips unlock during session creation. Defaults to false	true or false
unlockType	Unlock the target device with particular lock pattern instead of just waking up the device with a helper app. It works with unlockKey capability. Defaults to undefined. fingerprint is available only for Android 6.0+ and emulators. Read unlock doc in android driver.	[‘pin’, ‘password’, ‘pattern’, ‘fingerprint’]
unlockKey	A key pattern to unlock used by unlockType.	e.g., ‘1111’
autoLaunch	Initializing the app under test automatically. Appium does not install/launch the app under test if this is false. Defaults to true	true or false
skipLogcatCapture	Skips to start capturing logcat. It might improve performance such as network. Log related commands will not work. Defaults to false.	true or false
uninstallOtherPackages	A package, list of packages or * to uninstall package/s before installing apks for test. ‘*’ uninstall all of thrid-party packages except for packages which is necessary for Appium to test such as io.appium.settings or io.appium.uiautomator2.server since Appium already contains the logic to manage them.	e.g. “io.appium.example”, [“io.appium.example1”, “io.appium.example2”], ‘*’
disableWindowAnimation	Set device animation scale zero if the value is true. After session is complete, Appium restores the animation scale to it’s original value. Defaults to false	true, false
remoteAppsCacheLimit	Set the maximum number of remote cached apks (default is 10) which are pushed to the device-under-test’s local storage. Caching apks remotely speeds up the execution of sequential test cases, when using the same set of apks, by avoiding the need to be push an apk to the remote file system every time a reinstall is needed. Set this capability to 0 to disable caching.	e.g. 0, 5, 20
buildToolsVersion	Specify the Android build-tools version to be something different than the default, which is to use the most recent version. It is helpful to use a non-default version if your environment uses alpha/beta build tools.	e.g. ‘28.0.3’
androidNaturalOrientation	Allow for correct handling of orientation on landscape-oriented devices. Set to true to basically flip the meaning of PORTRAIT and LANDSCAPE. Defaults to false	true, false
enforceAppInstall	By default application installation is skipped if newer or the same version of this app is already present on the device under test. Setting this option to true will enforce Appium to always install the current application build independently of the currently installed version of it. Defaults to false.	true , false
ignoreHiddenApiPolicyError	Ignores Security exception: Permission denial alert and allows to continue the session creation process since Appium 1.18.0+. The error happens when Appium tries to relax hidden API policy, although some devices with a customized firmware deny such requests. Defaults to false.	true, false
mockLocationApp	Sets the package identifier of the app, which is used as a system mock location provider since Appium 1.18.0+. This capability has no effect on emulators. If the value is set to null or an empty string, then Appium will skip the mocked location provider setup procedure. Defaults to Appium Setting package identifier (io.appium.settings).	e.g., null, io.appium.settings, example.your.app
logcatFormat	Set the output format for logcat messages since Appium 1.18.0. Supported formats are listed in here. Please read logcat#outputFormat for more details about each format. Defaults to threadtime.	e.g., process
logcatFilterSpecs	Set the output filter rule for logcat messages since Appium 1.18.0. Please read logcat#filteringOutput for more details about the rule. Write and View Logs with Logcat is also helpful.	e.g., [’*:W’, ‘MyActivity:D’] (MyActivity is a tag)
