Finding and interacting with elements

Appium supports a subset of the WebDriver locator strategies:

• find by "tag name" (i.e., ui component type)
• find by "name" (i.e., the text, label, or developer-generated ID a.k.a 'accessibilityIdentifier' of an element) NOTE: the "name" locator strategy will be deprecated on mobile devices, and will not be a part of Appium v1.0
• find by "xpath" (i.e., an abstract representation of a path to an element, with certain constraints)

Appium additionally supports some of the Mobile JSON Wire Protocol locator strategies

• -ios uiautomation: a string corresponding to a recursive element search using the UIAutomation library (iOS-only)
• accessibility id: a string corresponding to a recursive element search using the Id/Name that the native Accessibility options utilize.

###Tag name mapping

You can use the direct UIAutomation component type name for the tag name, or use the simplified mapping (used in some examples below) found here:

Issues

There's a known issue with table cell elements becoming invalidated before there's time to interact with them. We're working on a fix

Examples

Find all the UIAButtons on the screen

WD.js:

driver.elementsByTagName('button', function(err, buttons) {
  // tap all the buttons
  var tapNextButton = function() {
    var button = buttons.shift();
    if (typeof button !== "undefined") {
      button.click(function(err) {
        tapNextButton();
      })
    } else {
      driver.quit();
    }
  }
  tapNextButton();
});

Ruby:

buttons = @driver.find_elements :tag_name, :button
buttons.each { |b| b.click }

Python:

[button.click() for button in driver.find_elements_by_tag_name('button')]

Find the element with the text (or accessibilityIdentifier) "Go"

WD.js:

driver.elementByName('Go', function(err, el) {
  el.tap(function(err) {
    driver.quit();
  });
});

Ruby:

@driver.find_element(:name, 'Go').click

Python:

driver.find_element_by_name('Go').click()

Find the nav bar text element where the text begins with "Hi, "

WD.js:

driver.elementByXpath('//navigationBar/text[contains(@value, "Hi, ")]', function(err, el) {
  el.text(function(err, text) {
    console.log(text);
    driver.quit();
  });
});

Ruby:

@driver.find_element :xpath, '//navigationBar/text[contains(@value, "Hi, ")]'

Find an element by tagName

Java:

driver.findElement(By.tagName("button")).sendKeys("Hi");

WebELement element = findElement(By.tagName("button"));
element.sendKeys("Hi");

List<WebElement> elems = findElements(By.tagName("button"));
elems.get(0).sendKeys("Hi");

Python:

driver.find_elements_by_tag_name('tableCell')[5].click()

Using the "-ios uiautomation" locator strategy

WD.js:

driver.element('-ios uiautomation', '.elements()[1].cells()[2]').getAttribute('name');

FindAndAct

If you want, you can find and act on an element in a single command (iOS-only). For example, you can find and click on an element in one call to Appium, using a special mobile: findAndAct command.

Python:

args = {'strategy': 'tag_name', 'selector': 'button', 'action': 'tap'}
driver.execute_script("mobile: findAndAct", args)

Pull to refresh using a swipe gesture

Python:

js_snippet = "mobile: swipe"
args = {'startX':0.5, 'startY':0.2, 'startX':0.5, 'startY':0.95, 'tapCount':1, 'duration':10}
driver.execute_script(js_snippet, args)

Note: driver.execute_script() is explained in Automating Mobile Gestures: Alternative access method)

Using The Appium Inspector To Locate Elements

Appium provides you with a neat tool that allows you to find the the elements you're looking for without leaving the Appium app. With the Appium Inspector (the i symbol next to the start test button) you can find any element and it's name by either clicking the element on the preview page provided, or locating it in the UI navigator.

Overview

The Appium inspector has a simple layout, complete with a UI navigator, a preview, and record and refresh buttons, and interaction tools.

Example

After launching the Appium Inspector (you can do this by clicking the small "i" button in the top right of the app) you can locate any element in the preview. In this test, I'm looking for the id of the "show alert" button.

To find the id of this button, I click the "show alert" button in the inspector preview. The Appium inspector then highlights the element in the UI navigator, showing me both the id and element type of the button I clicked.
