Appium
AppiumLibrary is a Mobile App testing library for Robot Framework.
Locating or specifying elements
All keywords in AppiumLibrary that need to find an element on the page take an argument, either a locator or a webelement. locator is a string that describes how to locate an element using a syntax specifying different location strategies. webelement is a variable that holds a WebElement instance, which is a representation of the element.
Using locators
By default, when a locator is provided, it is matched against the key attributes of the particular element type. For iOS and Android, key attribute is id for all elements and locating elements is easy using just the id. For example:
New in AppiumLibrary 1.4, id and xpath are not required to be specified, however xpath should start with // else just use xpath locator as explained below.
For example:
Appium additionally supports some of the Mobile JSON Wire Protocol locator strategies. It is also possible to specify the approach AppiumLibrary should take to find an element by specifying a lookup strategy with a locator prefix. Supported strategies are:
| Strategy | Example | Description | Note |
| identifier | Click Element | identifier=my_element | Matches by @id attribute | |
| id | Click Element | id=my_element | Matches by @resource-id attribute | |
| accessibility_id | Click Element | accessibility_id=button3 | Accessibility options utilize. | |
| xpath | Click Element | xpath=//UIATableView/UIATableCell/UIAButton | Matches with arbitrary XPath | |
| class | Click Element | class=UIAPickerWheel | Matches by class | |
| android | Click Element | android=UiSelector().description('Apps') | Matches by Android UI Automator | |
| ios | Click Element | ios=.buttons().withName('Apps') | Matches by iOS UI Automation | |
| nsp | Click Element | nsp=name=="login" | Matches by iOSNsPredicate | Check PR: #196 |
| chain | Click Element | chain=XCUIElementTypeWindow[1]/* | Matches by iOS Class Chain | |
| css | Click Element | css=.green_button | Matches by css in webview | |
| name | Click Element | name=my_element | Matches by @name attribute | Only valid for Selendroid |
Using webelements
Starting with version 1.4 of the AppiumLibrary, one can pass an argument that contains a WebElement instead of a string locator. To get a WebElement, use the new Get WebElements or Get WebElement keyword.
For example:
Importing
AppiumLibrary can be imported with optional arguments.
timeout is the default timeout used to wait for all waiting actions. It can be later set with Set Appium Timeout.
run_on_failure specifies the name of a keyword (from any available libraries) to execute when a AppiumLibrary keyword fails.
By default Capture Page Screenshot will be used to take a screenshot of the current page. Using the value No Operation will disable this feature altogether. See Register Keyword To Run On Failure keyword for more information about this functionality.
Examples:
| Library | AppiumLibrary | 10 | # Sets default timeout to 10 seconds | |
| Library | AppiumLibrary | timeout=10 | run_on_failure=No Operation | # Sets default timeout to 10 seconds and does nothing on failure |
